Forward geocoding: turn an address or place name into latitude/longitude. Returns ranked candidates with display name, coordinates, bounding box, address components, and an importance score so you can judge ambiguity rather than assume the first hit is right. Data from OpenStreetMap Nominatim. Costs $0.003 USDC per call on Base mainnet (eip155:8453), paid automatically from the wallet in EVM_PRIVATE_KEY.

Reverse geocoding: turn latitude/longitude into a street address with structured components. Returns null with a reason rather than a guess when the point is ocean or unmapped.

Weather for any coordinates worldwide: current temperature, feels-like, humidity, precipitation, wind speed, gusts and direction, plus up to a 7-day daily forecast with highs, lows, precipitation totals and probability. Every condition carries both the standard WMO code and plain text. Forecast rows are model output and the response says so. Pair with geocode to go from a place name to coordinates.

Web search: a free-text query returns ranked organic results with title, real destination URL, display URL and snippet. Sponsored rows are excluded. Results are not fetched or verified — a listing says nothing about whether the page is correct or still live. Pair with url_to_markdown to read any result.

Fetch a public article or PDF URL and return clean Markdown, using Firefox reader-mode extraction for HTML and text extraction for PDFs. Returns title, byline, excerpt, word count and a truncation flag. JavaScript is not executed, so client-rendered pages return an explicit not_extractable error rather than an empty page passed off as the article. Private, loopback and cloud-metadata addresses are refused. Costs $0.003 USDC per call on Base mainnet (eip155:8453), paid automatically from the wallet in EVM_PRIVATE_KEY.

Cryptographically secure random values from a CSPRNG: either random bytes (hex and base64url) or uniform integers in an inclusive range. Integers are rejection-sampled, so the distribution is uniform rather than modulo-biased. For randomness nobody else could have seen, generate it yourself — this is for callers that cannot.

OFAC sanctions screening. Checks a person or company against the US Treasury SDN and Consolidated lists — 19,600+ designated parties and 40,000+ names including every alias — and returns the matched record with its sanctions programs, designation remarks and a match score. Word order does not matter, because OFAC stores people as "SURNAME, Given". riskLevel is hit, possible or clear, and "clear" is scoped to the lists named in the response: EU, UK and UN are NOT screened. If the lists cannot be loaded you get an error, never a clear — a screening tool that says "no match" when it has no list is worse than one that is down.

Legal Entity Identifier (LEI) lookup from the GLEIF golden copy. Search by company NAME, not just by identifier — knowing the LEI already is the hard part. Returns the LEI, registered legal name, previous names, legal form, jurisdiction, legal and headquarters addresses, and the registration record. LAPSED, RETIRED and ANNULLED entities are returned with a lapsed flag rather than hidden, because a filtered record and no record look identical to a caller.
