Every agent-payable API.

Generate a valid RFC 5545 iCalendar file from JSON events: proper CRLF line endings, text escaping, line folding at 75 octets and a required DTSTAMP. The output imports cleanly into Google Calendar, Outlook and Apple Calendar. Use this when an agent needs to jSON events → valid .ics calendar file.

European option pricing with the Black-Scholes-Merton model: exact price for calls and puts plus delta, gamma, theta, vega and rho, with dividend yield support. Deterministic closed-form math — the numbers agents should quote instead of hallucinating option values. Use this when an agent needs to black-Scholes price + all five Greeks.

Generate the current TOTP two-factor code (RFC 6238) from a base32 secret — the same codes authenticator apps produce. Supports 6/8 digits, 30/60-second steps and SHA-1/256/512. Deterministic HMAC via Web Crypto; nothing is stored. Use this when an agent needs to rFC 6238 2FA codes from a base32 secret.

Look up any English word: part-of-speech definitions with usage examples, IPA phonetics, pronunciation audio when available, and synonym/antonym lists. Live from the free Dictionary API — definitions agents can quote verbatim instead of inventing. Use this when an agent needs to definitions, phonetics and synonyms for a word.

Resolve ENS names to addresses and look up reverse records (address → ENS name) via viem against Ethereum mainnet public RPCs. ENS data lives on Ethereum L1 regardless of where the wallet is active. Use this when an agent needs to eNS name ↔ address, bidirectional on Ethereum mainnet.

Full registration record for a domain via RDAP (the modern WHOIS): registrar, creation/expiration/last-updated dates with days-to-expiry, nameservers, EPP statuses and DNSSEC. Straight from the authoritative registry — the data agents should cite for domain diligence. Use this when an agent needs to registrar, dates, nameservers — registry data.

Validate a JSON document against a JSON Schema (draft 2020-12) with precise error paths — the exact check agents need before trusting structured output. Returns valid/invalid plus every violation with its JSON Pointer location and message. Use this when an agent needs to validate JSON against a draft 2020-12 schema.

Validate any EU VAT number against VIES — the European Commission's live registry: validity, registered trader name and address by member state. The check every B2B invoice flow needs before applying the reverse charge. Use this when an agent needs to vIES-verified VAT numbers, live from the EU.

Fetch a URL and grade its HTTP security headers: CSP, HSTS, X-Frame-Options, X-Content-Type-Options, Referrer-Policy, Permissions-Policy and COOP/CORP. Returns a 0–100 score, a letter grade, and a concrete recommendation for every missing header. Use this when an agent needs to grade a site's HTTP security headers + fix hints.

Convert Markdown to HTML with GitHub-flavored markdown support (tables, task lists, strikethrough, autolinks). Deterministic — the same markdown always yields byte-identical HTML, unlike LLM-approximated conversions. Use this when an agent needs to gFM markdown → clean HTML, exact output.

Recent earthquakes from USGS: filter by region (city or coordinates + radius), minimum magnitude and look-back window. Returns count, the largest event and a magnitude/place/depth table with links — live geophysical data agents cannot fabricate. Use this when an agent needs to recent quakes by region and magnitude from USGS.

Convert CSV to JSON (array of objects keyed by the header row) and JSON arrays back to CSV. Handles quoted fields with embedded delimiters, escaped quotes and multi-line values per RFC 4180 conventions. Use this when an agent needs to cSV to array-of-objects and back, with quote handling.

Compute sunrise, sunset, solar noon, civil dawn/dusk, golden hours and day length for any latitude/longitude and date — with the exact NOAA solar equations, accurate to about a minute. Answers agents repeatedly get wrong from memory. Use this when an agent needs to sun times, golden hour and day length for any place.

Aggregate traffic-crash context near an address. Perfect for: 'traffic crashes near this property', 'pedestrian or bicycle crash counts nearby', 'fatal crash context around an address'. Returns small-cell-suppressed official aggregates with explicit severity classes: local sources where wired plus nationwide FARS fatal-only fallback. Not route exposure, a forecast, score, or place verdict. Charge-free unless at least one count survives small-cell suppression.

AirScout air-quality query (current AQI, EPA activity verdict, and the cleanest window ahead)

Returns hourly surface concentrations from the CAMS European air-quality ensemble for a point in the cached DACH and Central Europe area. Available pollutants are CO, NO2, NO, O3, PM2.5, PM10 and SO2. Values come from the nearest 0.1 degree model cell and are labelled as a regional forecast rather than a street-level sensor reading. The local cutout is refreshed independently of paid calls, so Copernicus processing latency is not passed to the caller.

Delivers current PM2.5, PM10, ozone, and European Air Quality Index (AQI) levels for specified geographic coordinates.

Air quality now: US AQI with health band, PM2.5, PM10, ozone, NO2, UV — Genesis402 / UnyKorn Operator Network
