Screen a name against sanctions lists

The characteristic that matters: this route never returns a bare yes/no. Name matching is approximate — transliterations, aliases, reversed orders — and returning “match” without a score would turn a namesake into an accusation. Each list also returns its publication date and what that date means.

What the route returns

Catalogue description, exactly as agents read it:

Sanctions screening (AML/KYC): screen a person or company name against 6 official watchlist sources — UN consolidated, EU FSF, US OFAC SDN, UK Sanctions List, French national asset-freeze register, Swiss SECO list — six official lists in one call. Fuzzy watchlist matching with a 0-100 confidence score per hit — never a bare yes/no. Each list reports its entry count, publication date and what that date means. One AML screening call covers UN, EU, OFAC, UK, FR and CH.

Expected identifier

name parameter: an individual's or a company's name.

A wrongly formatted identifier returns 400 and is not billed — but it costs you a round trip. It is the leading cause of failed calls on the foreign routes.

Price and billing

Price: $0.02. The authoritative amount is the one in the 402 quote returned by the route itself — not this text, which derives from the same grid but is still just a page.

An error response cancels the payment: a 400, 404 or 503 is never billed. An upstream outage closes the route with a 503 rather than serving a degraded response.

How you pay

Every route is paid per call, in USDC or EURC on the Base network, over the x402 protocol: no account to create, no API key, no subscription. The first call returns a 402 quote your client settles, then replays the call. A failed call is never billed.

Would you rather have a euro invoice and prepaid credits? That is in preparation, and we will not announce a date until it is open. Write to contact@sirenic.eu and we will let you know when it opens.

Paid responses are Ed25519-signed: you can later prove what was served to you, and when. The whole catalogue is free to read in the OpenAPI document and in llms.txt.
