Counterparty Check (KYB facts)
Counterparty check (KYB preflight) in one call: give any of a company name, domain, LEI or crypto wallet address (plus an optional EU VAT number), get neutral sourced facts for vendor onboarding and supplier due diligence: sanctions screen of the name on OFAC, EU and UK lists with UN designations flagged, OFAC wallet check, GLEIF LEI match and status, domain age, registrar and email-auth, and an EU VAT number format check. No risk score or verdict. Signed receipt.

Paid to
0x39BF4378b74f9E19c5113b00b01f57d94537bad1The wallet the 402 directs payment to. Its whole payment record — every payer, every chain — is on the merchant page.

Provider
The payTo wallet does not resolve to a registered ERC-8004 agent. That is not a verdict on the service — most of the catalog is unregistered.

Copy the prompt and paste it into Claude, an MCP client or your own agent — it will vet this service and call it over the free read API. No key, no account.
GET api.roundhouseai.io/v0/endpoints
This endpoint's own trailing-30-day call count, as published by the upstream catalog and snapshotted daily. 4 snapshots so far. Verified volume counts only settlements with an on-chain EIP-3009 marker.

Using Roundhouse, look up the x402 service Counterparty Check (KYB facts) and tell me whether it is worth paying: what a call costs, whether the endpoint answered when last probed, and what its payment record actually shows. curl -s 'https://api.roundhouseai.io/v0/endpoints?q=Counterparty%20Check%20(KYB%20facts)' curl -s 'https://api.roundhouseai.io/v0/merchants/<the payTo wallet returned above>' Then call it: read the price from the live 402 at https://api.stablecoingateways.com/v1/counterparty-check, never from a cached figure, and pay with an x402 client. The /v0 API needs an API key (`authorization: Bearer rh_live_…`) on everything except /v0/unified* and /v0/endpoints. Either pay over x402 (mint a personal key for $0.01 at GET https://api.roundhouseai.io/v0/test/x402), or ask me for an organization key, which I create at https://roundhouseai.io/dashboard/connections. If you have neither, ask before going further. If you do not have Roundhouse tools or skills installed, read https://roundhouseai.io/skill.md first — it is the whole procedure.
