Fetch any URL and return its article content with the clutter stripped — nav, ads, sidebars, footers, scripts, styles, comments removed via heuristic extraction (<article> / <main> / role=main / densest block). Choose the output with `format`: markdown (default), text, both (JSON envelope), html (a self-contained readable reader-view page, raw text/html), or pdf (a clean typeset reading document, raw application/pdf). html/pdf are built from the same cleaned content, so they carry no live page, no third-party assets, no trackers. SSRF-guarded, 512KB body cap, 8s timeout, 5 redirects max. JSON formats return { url, finalUrl, title, markdown?, text?, wordCount, sourceBytes }. This uses a raw HTTP fetch (no JavaScript) — for client-rendered / SPA pages whose content only appears after JS runs, use /api/url/render (same formats, headless-rendered). For a pixel-perfect image of the live page use /api/ai/screenshot; to enumerate a page or sitemap into its links use /api/url/map.

Use for current events, market-moving developments, monitoring, and "what happened with X" questions. For general web results see /api/search/web; for Hacker News specifically see /api/news/hn-top.

Validate a European Union VAT number against the official VIES (VAT Information Exchange System) register in real time. Confirms whether the VAT identifier is currently registered for intra-EU trade and, when the member state discloses them, returns the registered business name and address. Covers the 27 EU member states (Greece as EL) plus Northern Ireland (XI); Great Britain (GB) is not in VIES. Pass either a full identifier (vat=DE811569869) or country + number. Returns {valid, countryCode, vatNumber, name, address, requestDate, reason}. When a member-state register is temporarily down, returns a retryable 503 rather than a false negative. Data from the European Commission VIES service.

/api/crypto/gas-oracle

Live EVM gas oracle. Returns latest block baseFeePerGas + slow/standard/fast tiers derived from priority-fee percentiles (p25/p50/p75) over the trailing 4 blocks, plus a 21,000-gas transfer cost estimate in the chain native unit.

Returns the most recent completed trading session: open, high, low, close, volume, VWAP, and trade count, plus the change and percent change versus the prior session, and company reference data (name, primary exchange, security type, currency, market cap). NOTE: this plan tier serves end-of-day / delayed data (the response flags delayed=true), suitable for daily snapshots, fundamentals context, and post-close analysis rather than real-time trading. Pass ticker as a US symbol (e.g. AAPL, MSFT, BRK.B). Market data by Massive (formerly Polygon.io).

/api/space/exoplanet

Search confirmed exoplanets in the NASA Exoplanet Archive (~6,000, updated weekly — past any LLM training cutoff). Filter by name (planet, partial), hostStar (partial), discoveryYear, or method (e.g. "Transit", "Radial Velocity", "Microlensing"). Each planet: name, host star + how many stars/planets in the system, discovery method/year/facility, orbital period, semi-major axis, radius (Earth radii), mass (Earth masses), equilibrium temperature, insolation; host-star spectral type/temperature/radius/mass; distance in parsecs + light-years; and RA/dec. Astronomy, habitability research, science education. Public-domain NASA data.

/api/flight/status

Live flight status and tracking. Pass ident as an airline flight designator (ICAO "UAL1" or IATA "UA1") or an aircraft tail number; returns recent and upcoming instances of that flight with origin/destination airports (ICAO/IATA/name/city/timezone), status, cancellation/diversion flags, scheduled vs estimated vs actual gate and runway times (out/off/on/in), departure and arrival delays, en-route progress percent, aircraft type and registration, and route distance. limit controls how many instances return (default 5, newest first by scheduled departure). Real-time operational data — answer "where is this flight, is it delayed, when does it land" with live values. For aircraft registry data see /api/aircraft/lookup; for airport metadata see /api/airport/lookup.

/api/crypto/token-price

Current spot price and market data for crypto assets.

Returns per-asset price, market cap, 24h volume, and 24h percent change, plus the data timestamp. Live market data past any training cutoff. Price data by CoinGecko.

/api/climate/station-history

Historical daily weather observations from NOAA GHCN-Daily for one station and date range (up to 366 days per call): max/min/avg temperature (°C), precipitation (mm), snowfall and snow depth (mm), wind (m/s). Coverage reaches back to the 1800s for long-running stations — actual measured values for "what was the weather on this date", not model recall. Pass a GHCN station id (e.g. USW00094728 = NYC Central Park); find the nearest station for any coordinate with /api/climate/station-near first. dataTypes selects elements (default TMAX,TMIN,PRCP). NOAA public-domain data.

Returns the word mark, LIVE/DEAD status with the detailed status description and date, filing and registration dates, current owner (name, entity type, citizenship), mark type (trademark / service mark / certification mark), standard-character flag, abandonment date when applicable, and the international classes covered with their descriptions. Authoritative real-time USPTO data — confirm a mark exists and is active before relying on it for clearance, licensing, or due-diligence work. Lookup is by number only (no text search); siblings: /api/patents/search, /api/law/case-verify.

/api/agent/memory/get

Read a memory entry for the calling agent. Namespace = your x402 signing pubkey. Returns 404 if the key doesn't exist in your namespace (or has expired via TTL). Response { key, value, etag, sizeBytes, createdAt, updatedAt, expiresAt }.

/api/medical/rxnorm

Normalize and verify drug names against RxNorm, the canonical US drug vocabulary from the NIH. Two modes: term ("tylenol 500mg", brand or generic, typos tolerated) returns ranked RxCUI candidates with normalized names and match scores; rxcui returns the canonical concept (name, term type like IN=ingredient / SBD=branded drug / SCD=clinical drug, suppression flag) plus related concepts — active ingredients, brand names, and available dose forms. Use before writing prescriptions data, drug interactions queries, or pharmacy integrations: verify the drug exists and get its stable identifier instead of trusting model memory. Sibling: /api/medical/icd10 (diagnosis codes). Public-domain NIH data.

/api/trade/tariff

Look up or search the US Harmonized Tariff Schedule (HTS / HS codes). Pass `code` for an exact HTS number (dots optional) — returns that line plus its 10-digit statistical suffixes with duty rates. Or pass `query` for free-text search (e.g. 'electric toothbrush', 'roasted coffee') → ranked candidate HS codes by hierarchical heading. Each result: htsno, chapter, description, full heading path, units, and duty rates (general/MFN, special/FTA, column-2). ~29.6k lines, public-domain USITC data. The deterministic backbone for tariff classification in import/export and ERP item setup.

/api/validate/cusip

Validate a CUSIP (9-character US/Canada securities identifier) with its mod-10 weighted check digit. Returns {valid, cusip, checkDigit, reason}. Catches transposed characters in security master / holdings data that a length check misses. Structure + checksum only.

/api/validate/sscc

Validate a GS1 SSCC (Serial Shipping Container Code) — 18 digits with the GS1 mod-10 check digit. SSCCs identify individual logistic units (pallets, cases) and are the key field in shipping/ASN (EDI 856) flows. Returns {valid, sscc, extensionDigit, checkDigit, reason}.

/api/convert/unit

Convert a value between units of measure: mass (g, kg, mg, lb, oz, t, st), length (m, km, cm, mm, in, ft, yd, mi), volume (l, ml, m3, gal, gal-imp, qt, pt, cup, floz, tbsp, tsp), area (m2, km2, ft2, acre, ha), and temperature (C, F, K). Units are matched case-insensitively with common aliases (kg/kilogram/kgs). Returns {value, from, to, dimension, result}. Exact factors — the ground-truth answer a CPG/ETL pipeline needs instead of an LLM approximating conversions. Cross-dimension conversions (kg→m) return 400.

/api/validate/gtin

Validate a product barcode — GTIN-8/12/13/14, UPC-A, EAN-13, or ISBN-10/13 — with the GS1 mod-10 check digit (ISBN-10 uses mod-11). Returns {valid, type, gtin14 (canonical 14-digit form, left-padded), checkDigit, reason}. Normalizes every product identifier to one GTIN-14 key so a product-master/ETL pipeline can dedupe and validate SKUs in one deterministic call instead of doing checksum math in an LLM.

/api/validate/gln

Validate a GS1 GLN (Global Location Number) — 13 digits with the GS1 mod-10 check digit. GLNs identify trading parties and physical locations (ship-to, bill-to, warehouse) across CPG supply chains and EDI. Returns {valid, gln, checkDigit, reason}. Catches transposed digits a length check misses.

/api/validate/aba

Validate a US bank ABA routing number with the Federal Reserve weighted mod-10 checksum (3-7-1) — not just a 9-digit regex. Returns {valid, routingNumber, district (routing-symbol class), reason}. Catches transposed digits in ACH/wire setup that a length check misses. Structure + checksum only; not a bank-directory existence lookup.

/api/weather/alerts

Live US severe-weather alerts from the National Weather Service. Pass a point ("lat,lon") to get every active watch, warning, and advisory for that exact location, or an area (2-letter US state or marine zone code) for area-wide alerts. Optionally filter by severity or urgency. Each alert returns the event type, severity, urgency, certainty, headline, affected-area description, issuing office, recommended public response, onset / expiry / end times, and the full hazard description plus protective-action instructions. Results are sorted most-severe first and capped by limit, with the true total reported. Public-domain NOAA / National Weather Service data, refreshed in real time.

Live EVM transaction status and receipt lookup. Give a transaction hash + chain and get back whether it mined successfully, reverted, or is still pending in the mempool, plus block number, confirmations, timestamp, sender and recipient, value transferred (native unit), gas used, effective gas price, total fee paid, any contract created, and event-log count. Chains: base, ethereum, polygon, arbitrum, optimism. Real-time post-training chain state — use it to confirm a payment settled, detect a reverted transaction, or wait for confirmations before acting. Unknown hash returns 404. Sibling of /api/crypto/gas-oracle (fees) and /api/crypto/address-validate (format).

/api/validate/lei

Validate a Legal Entity Identifier (LEI, ISO 17442) with the ISO 7064 mod-97-10 check digits — not just a 20-character regex. Returns {valid, lei (normalized), louPrefix (issuing LOU), checkDigits, reason}. Confirms a counterparty/vendor LEI is well-formed before lookup; pairs with GLEIF data for name + ownership resolution. Structure + checksum only.

/api/validate/iban

Validate an International Bank Account Number (IBAN) with full ISO 13616 checks: country-specific length and the ISO 7064 mod-97 checksum (not just a regex). Returns {valid, iban (normalized), formatted (4-char groups), countryCode, checkDigits, bban, reason}. Catches transposed digits and wrong-length accounts that a format check misses, and returns the canonical form so a glue/ETL pipeline can validate AND normalize bank details in one deterministic call. ~85 countries. No bank directory lookup — structure + checksum only.

/api/search/web

Live web search. Returns ranked results with title, URL, snippet description, site name, and page age — fresh information past any model training cutoff. Supports count (1-20), offset for paging, country (2-letter, e.g. US), freshness (pd=past day, pw=past week, pm=past month, py=past year, or a YYYY-MM-DDtoYYYY-MM-DD range), and safesearch (off/moderate/strict). Use for current events, fact verification, finding documentation, and research. Independent search index. For news-specific results with sources and timestamps see /api/news/search.

/api/space/skywatch

One call → what's notable in YOUR sky right now, for a lat/lon. Synthesizes three sources: (1) the live almanac — sun up/down, moon phase + illumination, and which of the 7 naked-eye planets are currently above your horizon with their altitude/azimuth/magnitude; (2) near-Earth asteroid close approaches over the next 7 days (designation, date, distance in lunar distances); and (3) the ISS — its current sub-point, and whether it is above your horizon right now with look angles. Each section reports found/error independently. The "is it dark, what's up, anything passing" digest for stargazers and astrophotographers. For the raw almanac alone see /api/space/sky-tonight.

/api/law/trademark-search

Search US trademarks by wordmark text, owner name, or goods/services — the text search the USPTO offers no public API for. Pass `query` for full-text search (ranked best-match first), or `serial` / `registrationNumber` for an exact record. Filter with `field` (mark|owner|all), `status` (live=registered+pending only, default; all=includes dead/abandoned), and `intlClass` (Nice class, e.g. 9). Returns each mark's wordmark, serial, registration number, status (+ live flag), filing/registration/abandonment dates, owner, international classes, and goods/services. Corpus: USPTO full trademark register (public domain). Use law.trademark-status for live USPTO prosecution detail on a known serial.

/api/space/observe

Compute where any asteroid or comet is in the sky and whether you can see it. Give a body (designation/number/name, e.g. "433 Eros", "Ceres", "2024 YR4") and optionally your lat/lon and a time (ISO, default now). Returns the body's identity (NEO/PHA flags, orbit class, absolute magnitude H), its geocentric right ascension + declination, the constellation it's in, geocentric + heliocentric distance (AU), solar phase angle, and its apparent visual magnitude (IAU H-G model — how bright it appears now). With lat/lon it adds altitude/azimuth, whether it's above your horizon, a visible-now flag (up AND sky dark), and the best viewing window in the next 24 hours (when it's highest during darkness). Orbital position is computed locally from JPL elements — VALIDATED against JPL Horizons to <0.1 arcminute. Stargazing, astrophotography planning, occultation/observation prep. For the body's static physical + orbital params see /api/space/body.

/api/crypto/ens-resolve

Resolve ENS (Ethereum Name Service) names and addresses live on Ethereum mainnet. Pass query as either an ENS name (e.g. "vitalik.eth") → returns the Ethereum address it points to, or a 0x address → returns its primary ENS name (reverse record). Either way it also returns the profile text records: avatar, email, url, twitter (com.twitter), github (com.github), and description. A live on-chain lookup agents can't do from their sandbox, and ENS records change after training cutoffs. Wallet UX, address-book resolution, on-chain identity. Returns address:null for an unregistered or unset name.

/api/tls/cert-info

Open a live TLS connection to a host and return its certificate. Give a host (and optional port, default 443). Returns the negotiated TLS protocol + cipher, whether the chain validates against system roots, and the leaf certificate's subject + issuer (CN/O/C), validity window (valid-from / valid-to), days until expiry + expired flag, serial number, SHA-256 fingerprint, Subject Alternative Names, and the chain length. A genuine network probe agents can't do from their sandbox — for cert-expiry monitoring, TLS audits, and verifying who issued a site's certificate. SSRF-guarded: the host must resolve to a public address. Self-signed and expired certs are reported (not rejected).

/api/nonprofit/screen

Look up US 501(c) nonprofits and screen each result against the OFAC sanctions list in one call. Pass q (organization name) or ein; each matched organization returns its registry record (EIN, name, location, NTEE code, subsection) plus a sanctions block — flagged status, match count, and the matching SDN entries with confidence scores. Grant-making due diligence, donation compliance, and charity-fraud triage. Components also standalone: /api/nonprofit/search (registry only) and /api/law/sanctions-check (screen any name). Same composition family as /api/business/entity-screen.

/api/space/launches

Upcoming or recent orbital rocket launches from The Space Devs' Launch Library 2 — the live manifest behind most launch-tracking apps. `when`=upcoming (default) or previous. Optional `search` filters by rocket, provider, or mission text (e.g. "Starship", "SpaceX", "Artemis"). Each launch: name, status (Go/TBD/Success/Failure), NET launch time + window (UTC), launch provider, rocket configuration, pad + location, mission name/type/orbit/description, and whether a webcast is live. Real-time data agents can't get from training. Public CC-BY data (attribute The Space Devs).

/api/business/entity-screen

KYC in one call: look up a business in a US state registry (NY, CO, CT) AND screen it against the OFAC sanctions list. Give a state and a name (or exact entityId). Returns the matched registered entities (id, type, status, jurisdiction, address, registered agent) and, for each, a sanctions screen of the entity name AND its registered agent against OFAC SDN — with fuzzy-match confidence and a flagged boolean. Counterparty due-diligence, vendor onboarding, AML. Composition of /api/business/sos-search + /api/law/sanctions-check (each section reports found/error independently). Note: sanctions screening is name-based and probabilistic — review flagged matches manually.

/api/space/body

Look up any asteroid or comet in NASA JPL's Small-Body Database by designation, number, or name (e.g. "433", "Eros", "433 Eros", "1P/Halley", "2024 YR4"). Returns full name + kind + orbit class (e.g. Amor, Apollo, Jupiter-family comet), NEO and potentially-hazardous-asteroid flags, physical params (absolute magnitude H, diameter, extent, rotation period, albedo, density, spectral type), and orbital elements (eccentricity, semi-major axis, perihelion/aphelion, inclination, period, Earth MOID, observation arc). Astronomy, planetary-defense, and mission-planning research. Public-domain NASA/JPL data; for a body's near-Earth close approaches see /api/space/close-approaches.

/api/bio/species

Resolve any organism by scientific or common name to the GBIF taxonomic backbone — the canonical free reference for life on Earth. Returns the accepted scientific name + canonical name, taxonomic rank and status, the match type/confidence, the full classification (kingdom → phylum → class → order → family → genus → species), up to 8 English vernacular (common) names, the count of recorded occurrences worldwide, and the GBIF species URL. Biodiversity, ecology, education, and as a taxonomy normalizer for other pipelines. Fuzzy-matches misspellings. CC-BY GBIF data.

/api/aircraft/profile

Identify a US-registered aircraft by tail (N-number) or icao24 Mode-S hex, AND screen its owner and operator against the OFAC sanctions list — in one call. Returns the full aircraft record (registration, manufacturer, model, type, serial, owner, operator, year built) plus a sanctions screen of the owner and operator names against OFAC SDN, with fuzzy-match confidence and a flagged boolean. OSINT, asset-tracing, sanctions-evasion investigation, due diligence. Composition of /api/aircraft/lookup + /api/law/sanctions-check (the sanctions section reports found/error independently). Note: screening is name-based and probabilistic — review flagged matches manually.

/api/space/satellite

Compute the current position of any cataloged Earth-orbiting satellite by NORAD catalog number (e.g. 25544 = ISS, 20580 = Hubble), using fresh Celestrak orbital elements propagated with SGP4. Returns sub-point latitude/longitude, altitude (km), and speed (km/s) for the requested instant (default: now; pass `at` as an ISO timestamp for any time within a few days of the elements' epoch). Supply observer `lat`/`lon` (and optional altKm) to also get look angles — azimuth, elevation, slant range, and whether the satellite is above your horizon — for visual/antenna pointing. Satellite tracking, pass prediction, ground-station planning. Public-domain orbital data; physical/mission metadata is not included.

/api/gov/fec-expenditures

Search FEC Schedule B — every itemized disbursement (spend, vendor payment, operating expenditure, contribution out, transfer) made by a federal political committee (>157M rows). Filter by committeeId, recipient name / city / state, disbursement purpose category (Administrative / Fundraising / Media / Polling / Salary / Travel / Operating / Contribution / Loan / etc.), description text, amount range, cycle, date range. Sort by date or amount. Every row carries: who got paid, when, how much, for what, with link to underlying PDF.

Common organism taxids: human 9606, mouse 10090, zebrafish 7955, fruit fly 7227, yeast 559292.

Discover the URLs a page or sitemap points at in a single fetch. Point it at an XML sitemap or sitemap-index and it returns the <loc> URLs; point it at an HTML page and it returns the <a href> links — auto-detected. URLs are resolved to absolute, de-duplicated, fragment-stripped, and http(s)-only. `limit` (1-2000, default 200) caps the count; `sameHostOnly` keeps only links on the same host. Single SSRF-guarded fetch, no JavaScript, stateless — NOT a recursive crawler: to go deeper, call map again on a child sitemap or a discovered page. Returns { url, finalUrl, source: "sitemap"|"links", count, capped, urls }.

/api/validate/bic

Validate a SWIFT/BIC code (ISO 9362): 8 or 11 characters = 4-letter institution + 2-letter ISO country + 2-char location + optional 3-char branch, with the country position checked against ISO 3166. Returns {valid, bic, institution, country, location, branch, reason}. Structure validation only — not a SWIFT-directory existence lookup.

/api/agent/memory/put

Write or replace a memory entry for the calling agent. Namespace = your x402 signing pubkey (each unique paying wallet gets its own private KV store). Body { key, value, ttlSeconds? }. Returns { key, etag, sizeBytes, createdAt, updatedAt, expiresAt }. Key 1-200 chars from [A-Za-z0-9._/-]. Value is arbitrary JSON, max 64 KiB serialized.

Fetch the authoritative text of any section of the US Code of Federal Regulations by title and section number — for example title 12, section 1026.43 returns Regulation Z’s ability-to-repay standards. Returns the canonical citation, section heading, full plain text, Federal Register source credit, the as-of date, and a link to the official eCFR page. An optional date parameter (YYYY-MM-DD) retrieves the historical text in force on that date, back to 2017. Data from the Electronic Code of Federal Regulations (US GPO / Office of the Federal Register), public domain, updated daily — verify regulatory citations against the authoritative source instead of relying on model memory.

Verify and search ICD-10-CM diagnosis codes against the official US code set (FY2026, ~98k entries). Pass code (with or without the dot, e.g. E11.9 or E119) to confirm the code exists and list its more-specific child codes, or q to keyword-search code descriptions (e.g. "type 2 diabetes neuropathy"). Optional billable_only=true restricts results to codes valid for claim submission; limit caps results (1-50, default 10). Returns a verified flag, the exact match if any, and matched codes with billable status plus short and long descriptions. Data: CMS/NCHS ICD-10-CM (public domain), refreshed each US fiscal year. Use to confirm diagnosis codes are real and current before placing them in claims, prior authorizations, or clinical documents.

/api/law/usc-section

Fetch the authoritative current text of any United States Code section by title and section number — for example title 17, section 107 returns the fair-use statute. Returns the canonical citation, heading, hierarchy context (title/chapter), full statutory plain text, the Statutes-at-Large source credit, and a link to the official OLRC page; set includeNotes=true to also get editorial notes (amendment history, effective dates). Hyphenated and lettered sections like 1395w-4 or 78j work. Data from the Office of the Law Revision Counsel current ("prelim") edition, public domain — verify statutory citations against the authoritative source instead of relying on model memory.

Defaults: 1280×720 PNG, networkidle2 wait, ad-blocking on. Use cases: visual verification, archival, change detection, OG-card generation, RSS thumbnails.

/api/airport/near

Airports within a radius of a coordinate, sorted by distance. Query: lat (-90..90), lon (-180..180), radius_km (1-2000, default 200), limit (1-100, default 20), type (optional: large_airport|medium_airport|small_airport|heliport|seaplane_base|balloonport|closed), country (optional 2-letter ISO 3166-1), scheduled_service (optional bool, true = commercial-service airports only). Returns { query, count, airports: [{ id, ident, name, iataCode, icaoCode, type, latitude, longitude, distanceKm, ... }] }.

/api/countdown/gif

Animated countdown GIF from the current UTC time to endDate. Always uncached. Supports 5 templates (default, minimal, neon, retro, corporate) and full customization: colors, fonts, dimensions, padding, cell padding, labels, dividers. Animates for `seconds` frames at `fps`.

/api/hash/compute

Compute one or more cryptographic digests (MD5, SHA-1, SHA-2 family, SHA-3 family, BLAKE2) of a string or hex/base64-encoded byte buffer. Returns hex or base64-encoded digests.

/api/dns/lookup

Resolve a hostname over public DNS and return parsed records. Query: host (required FQDN), types (comma-separated: A,AAAA,MX,TXT,NS,CAA,SRV,CNAME,PTR,SOA — default A,AAAA,MX,TXT,NS), resolver (cloudflare|google|quad9|opendns, optional). Returns one normalized JSON shape per record type with per-type error pass-through. Reserved/local TLDs (.local, .internal, .invalid, .test, localhost) are rejected. 4s per-query timeout.

/api/ai/translate

Translate text. POST { text, targetLanguage, sourceLanguage? } — language codes are BCP-47 (e.g. "en", "es-MX", "zh-Hans"). Source auto-detected when omitted. Returns { text, targetLanguage, detectedSourceLanguage, confidence (high|medium|low) }. Best for short-to-medium passages; chunk long documents on your side.

/api/geocode/address

Forward geocoding — free-text address or place name → latitude/longitude plus structured address components (houseNumber, road, suburb, city, county, state, postcode, country, countryCode). Query: q (2-500 chars), limit (1-10, default 5), country (optional 2-letter ISO 3166-1 bias). Underlying data is OpenStreetMap (ODbL). Sister: /api/geocode/reverse.

/api/chem/compound

Look up a chemical compound by CID, common/IUPAC name, SMILES, or InChIKey. Returns CID, preferred name, IUPAC name, molecular formula, molecular weight, exact mass, SMILES, connectivity SMILES, InChI, InChIKey, XLogP, formal charge, the 10 most-common synonyms, a PubChem permalink, and source attribution. Data is sourced from NIH PubChem (public domain). Provide exactly one of cid, name, smiles, or inchikey.

/api/ai/extract

Extract structured data from a webpage. POST { url, schema, instruction? }. The schema is a JSON Schema object (top-level type:"object") describing the shape you want back; output is guaranteed to conform. Returns { url, finalUrl, extracted, meta:{ truncated } }.

/api/agent/marketplace/register

Register or update the calling agent's listing in the agent-to-agent marketplace. Owner = your x402 signing pubkey (one listing per pubkey, re-register to update). Body { name, description, capabilities[], endpointUrl?, priceUsd?, network?, payTo?, status?, metadata? }. Listings appear in agent.marketplace.discover and are scored by agent.marketplace.review outcomes from other agents. Designed as the registrar for the emerging agent-to-agent economy: capable agents publish themselves here, generalist agents find them, x402 settles per call, reviews accrue.

/api/barcode/generate

Generate QR / Aztec / Data Matrix / PDF417 codes from structured payloads (url, wifi, vcard, vevent, email, sms, tel, geo, bitcoin, json, text). QR supports rounded or dotted modules, solid colors or linear/radial gradients, transparent backgrounds, configurable error correction, and a centered logo image (URL or data URI).

/api/agent/marketplace/review

Post a review of another agent in the marketplace. Reviewer = your x402 signing pubkey; reviewed = target agent's namespace. Outcome is one of 'success' | 'failure' | 'partial'. Optional rating (1-5), comment (≤500 chars), txHash (the on-chain settlement of the underlying agent-to-agent transaction) and network. Reviews are insert-only — they form an append-only reputation log. One review per (reviewer, reviewed, txHash) when txHash is set.

/api/law/sanctions-check

Fuzzy-match a name (person, company, vessel, aircraft) against the US Treasury OFAC Specially Designated Nationals list. POST { query, threshold?, limit?, sourceList? }. Returns ranked matches with similarity scores, entity type, sanctions programs, aliases, and remarks. Threshold default 0.4; scores ≥ 0.85 flagged as hasHighConfidenceMatch. List refreshed daily from public US Treasury data.

/api/ipinfo/bulk

Geolocate up to 100 IPv4 or IPv6 addresses in a single call. Pass an array of IPs; results come back in input order. Each successful entry includes country (name + ISO code), region (name + code), city, postal code, lat/lon (city-level precision), timezone, and network info (ISP, organization, AS). Failed entries include an error object instead of geo fields, plus okCount/failedCount totals. Far cheaper than 100 single calls to /api/geo/ip when enriching logs, access lists, or analytics batches.

/api/transcribe/audio

Transcribe an audio file to text. POST { url, language?, diarize? } — the audio is fetched from your URL (wav, mp3, m4a/aac, ogg/opus, flac, webm; up to 15 MB and 15 minutes per call — split longer recordings and call once per segment). Returns the full punctuated transcript, overall confidence, audio duration, detected or specified language (BCP-47, e.g. "en", "es"), word-level timestamps with confidences, and — with diarize=true — speaker-segmented utterances (who said what, when). High-accuracy speech recognition for meeting notes, podcast processing, voicemail handling, and media monitoring.

/api/law/case-verify

Verify US legal case citations in a passage of text. POST { text } where text contains one or more citations (e.g. "Marbury v. Madison, 5 U.S. 137 (1803)"). Returns per-citation results with canonical case name, court, year, docket, citationCount, and a public CourtListener URL — or flags the citation as unverified. Anti-hallucination check for legal LLM output. Underlying opinions are public domain; CourtListener (Free Law Project) is the corpus.

/api/image/compress

Compress an image. POST exactly one of { url } or { imageBase64 }, plus optional { format?: auto|png|jpeg|webp|avif (default auto = keep input format), quality?: 1-100 (default 75), lossy?: bool (default true), effort?: 1-10 (default 6) }. Returns compressed image bytes directly with X-2s-* headers: Original-Bytes, Compressed-Bytes, Saved-Percent, Output-Format, Source-Format, Source-Width, Source-Height, Process-Ms. Limits: 5MB URL fetch, ~3MB inline body, 4096 × 4096 input pixels. Animated GIF input becomes animated WebP when format=webp or auto.

/api/html/to-markdown

Convert raw HTML you already have into clean reading markdown — no URL fetch. POST { html }. Strips scripts, styles, nav, ads, and comments, extracts the main article content, and returns markdown (headings, links, lists, emphasis preserved), plain text, the page title, and a word count. Use when you scraped or generated HTML elsewhere and want clean markdown without a round-trip. For fetching + cleaning a live URL instead, use /api/url/clean (or /api/url/render for JavaScript-rendered pages). Pure conversion, no network.

/api/validate/batch

Validate up to 100 identifiers of mixed kinds in a single deterministic call. Pass items=[{type,value}] where type is one of: iban, gtin, aba, lei, bic, gln, sscc, isin, cusip. Each result (returned in input order, with its index and type) carries {valid, reason} plus the same type-specific fields the single-identifier endpoints return (e.g. gtin14, countryCode, district). One unsupported type or one bad value degrades to that item's valid:false — it never fails the batch. meta carries validCount/invalidCount. This collapses a record's worth of per-field checksum checks (IBAN + BIC + GTIN + LEI + …) into one round-trip instead of one LLM/HTTP hop per field.

/api/law/opinion

Fetch the full text of a US court opinion by CourtListener opinion ID OR by citation. Returns plain text (preferred), HTML fallback, case metadata (case name, court, year, docket, citation), opinion type (lead/concurrence/dissent), author, and a list of alternate opinions in the same cluster. POST { opinionId?: number, citation?: string } — exactly one required. Anti-hallucination follow-up to case-verify: once you confirm the citation exists, fetch the text. Backed by CourtListener (public-domain underlying corpus).

/api/vehicle/decode-wmi

Decode a 3-character World Manufacturer Identifier (the first three characters of a VIN) to the assigning manufacturer. Returns full manufacturer legal name, common short name, make, vehicle type, and the date NHTSA published the assignment. Useful for partial-VIN analysis — crash reports, damaged-vehicle photos, fleet records — where only the WMI is recoverable. Backed by NHTSA.gov vPIC; data is public-domain US government records.

/api/space/weather

Current space weather from NOAA SWPC public feeds. Returns the latest planetary K-index (3-hour geomagnetic activity), solar wind plasma (density / speed / temperature from ACE/DSCOVR at L1), GOES X-ray flux with NOAA flare class (A/B/C/M/X), and the current NOAA R (radio blackout) / S (solar radiation) / G (geomagnetic storm) scales plus a 24-hour forecast in 6-hour windows. All timestamps are ISO 8601 UTC. No parameters. Useful for aurora forecasting, HF-radio propagation, satellite-operations planning, and GPS-degradation alerts. Data is public domain (NOAA / US government work).

/api/timezone/lookup

Resolve a coordinate to its IANA timezone and return the current UTC offset, local wall time, DST status, and short abbreviation. Query: lat (-90..90), lon (-180..180), at (optional ISO 8601 instant; defaults to now). Returns { tz, abbreviation, offsetMinutes, offsetHours, localTime, observesDst, isDst, januaryOffsetMinutes, julyOffsetMinutes, instant, source }. Polygon lookup against a CC0 timezone boundary index; offsets and DST come from the runtime tzdata so transition rules stay current. Use when scheduling for a coordinate, converting timestamps to local wall time, or checking whether a location is currently observing daylight saving.

/api/nutrition/food

USDA FoodData Central nutrition lookup. Two modes: search (query=cheddar cheese) returns matching foods with fdcId, description, data type, category, and brand; detail (fdcId=328637) returns the full analyzed nutrient profile — energy, protein, fats, carbohydrates, vitamins, minerals — with USDA nutrient numbers, amounts, and units (per 100 g/ml unless serving fields indicate otherwise), plus ingredients for branded foods. Filter search by dataType: Foundation and SR Legacy are lab-analyzed generic foods, Branded is the packaged-food label corpus, Survey (FNDDS) is as-consumed dishes. Authoritative USDA data covering ~400k foods — use real analyzed values instead of model-estimated nutrition facts.

/api/gov/usgs-water

Real-time water data from USGS NWIS stream / river / groundwater gauges within a bounding box around lat/lon. Returns each site's latest reading per requested variable: streamflow (00060, ft³/s), gage height (00065, ft), water temperature (00010, °C), precipitation (00045, in), and others. Each reading: site code + name, lat/lon, variable name + description + unit, value (or null if no data / sentinel), qualifier codes (e.g., 'P' = provisional, 'A' = approved), observed timestamp. Free public-domain data from waterservices.usgs.gov.

/api/gov/fec-candidate

Search US federal political candidates via the OpenFEC API. Filter by free-text q (name match), candidate ID (e.g. H0VA01076), state, district, party (DEM, REP, IND, LIB, GRE, etc.), office (P=President | S=Senate | H=House), election cycle (even years), election year, and hasRaised (only candidates with reported receipts). Returns FEC candidate ID, name, party, office, state/district, incumbency status, active-through cycle, first/last file dates, cycles, principal committee linkage. Use the candidate ID returned here to fetch their committees with /api/gov/fec-committee.

/api/validate/isin

Validate an ISIN (International Securities Identification Number, ISO 6166): 2-letter country prefix + 9-char NSIN + Luhn check digit. Returns {valid, isin, country, nsin, embeddedCusip (for US/CA), checkDigit, reason}. Catches transposed characters in security master data that a regex misses. Structure + checksum only.

/api/geo/postal

Resolve a postal/ZIP code to its place name(s), administrative divisions, and coordinates. Pass `postalCode` and a 2-letter `country` (default US). Returns each matching locality: place, admin1 (state/province name + code), admin2 (county/district), and lat/lon. International — covers major markets (US, GB, CA, DE, FR, AU, NL, ES, IT, CH, SE, MX). Use it to normalize and enrich addresses, derive the state/county for a ZIP, or geolocate a postal code in an ETL pipeline.

/api/property/nyc-violations

NYC Housing Preservation & Development (HPD) violations — every notice of violation issued at a multi-family building. Search by `bbl` (10-digit) or `address` (street_name substring). Filter by `classCode` (A=least severe, B=hazardous, C=immediately hazardous) and `currentStatusOnly=true` to limit to open violations. Each row carries violation id, building id, full address + apartment + story, inspection + approved + certify-by + correct-by dates, current status + status date, and the narrative NOV description. Use for landlord-history, code-enforcement, and tenant-rights agents.

/api/space/close-approaches

List near-Earth asteroid/comet close approaches to Earth within a date window and maximum distance, from NASA JPL's Close-Approach Data API. Filter by dateMin / dateMax (YYYY-MM-DD) and distMaxAu (max approach distance in AU; default 0.05 AU ≈ 19.5 lunar distances). Each approach: object designation, close-approach date (UTC), nominal + minimum distance in AU and lunar distances, relative velocity (km/s), and absolute magnitude H (a size proxy). Sorted nearest-first. Planetary-defense, observation planning, and "what's passing by this month" queries. Public-domain NASA/JPL data; for full physical/orbital params of a listed object see /api/space/body.

/api/space/system

Profile a confirmed exoplanetary system by host-star name (e.g. "TRAPPIST-1", "Kepler-90", "TOI-700"). Groups all the star's known planets into one view, summarizes the host star (spectral type, temperature, radius, mass, distance in light-years), and COMPUTES the star's habitable ("Goldilocks") zone — inner and outer boundary in AU, derived from the stellar luminosity (effective temperature + radius vs. the Sun) — then flags which planets orbit within it. Each planet: radius/mass (Earth units), orbital period, semi-major axis, equilibrium temperature, and in-habitable-zone flag. Astronomy, habitability research, education. Built from the NASA Exoplanet Archive (the same data as /api/space/exoplanet) plus the computed HZ. Public-domain NASA data.

/api/space/sky-tonight

Observer-local sky almanac for any lat/lon and time (default now). Returns the Sun's next rise/set + current altitude/azimuth; the Moon's rise/set, current alt/az, phase angle, phase name (New → Full → Waning Crescent), illuminated fraction, and next moon quarter; and for all seven non-Earth planets (Mercury→Neptune): altitude, azimuth, RA/dec, distance (AU), apparent magnitude, and whether each is currently above the horizon. Computed from first principles (astronomy-engine, sub-arcminute) — no external service, no key. Stargazing, astrophotography planning, 'what's up right now', is-it-dark-yet. `at` accepts any ISO timestamp.
