How do I check a counterparty (sanctions, LEI and bank status) in one call?

Call GET https://x402-bazaar-rank.x402-bazaar-rank-worker.workers.dev/check/counterparty?name=Deutsche%20Bank&country=DE for $0.015. One call screens the name (and an optional wallet address) against 5 sanctions lists loaded now (OFAC SDN, 2026-10-21; UK Sanctions List, 2026-10-16; EU Financial Sanctions, 2026-10-23; Canada Consolidated Autonomous Sanctions, 2026-10-15; US Consolidated Screening List, 2026-10-25), adds the entity's GLEIF LEI record and, for a US bank, its FDIC status. Each section has its own status (ok, not_found, unavailable or not_applicable), source and date, and a short list of flags. Screening only, not legal advice and not clearance.

The full answer

/check/counterparty - $0.015 per call: Counterparty check (sanctions, LEI, US bank status): the exact route this page describes
/sanctions/check - $0.005 per call: only the sanctions screening of one wallet address or name
/company/lei - $0.005 per call: only the GLEIF LEI record, with parents

Paid routes answer HTTP 402 with the payment requirements until paid over x402 or MPP (no account or key); see how to pay, pay without a client, OpenAPI. The figures on this page are also at ?format=json.

How this was measured

The sanctions section is the core: it reads the daily index of the five lists, and a call is refused before any charge when that index is missing, older than 48 hours or being updated, when the name is made only of very common words or when it is not in Latin script. The LEI and US-bank sections may fail on their own; they are then returned with an honest status and a flag, and the answer is still sold.
A wallet address is compared exactly; a name is compared by similarity, so a possible match is a lead for a person to review, not a verdict. No match does not mean a party is cleared.
The sections run in parallel, each with its own 15-second deadline; a section over it is shown as unavailable, never left out silently.
