KYB Check
Use when an agent must vet a company or counterparty before paying, onboarding or invoicing. Input: name, optional country (ISO2), lei, vat (EU, with prefix). Output: JSON summary (sanctions hits, LEI found/status, VAT valid), sanctions matches across OFAC SDN, EU and UK lists, GLEIF entity record with parents, VIES VAT result; a down VIES/GLEIF marks only that part. Not a legal determination. Example: ?name=Siemens+AG&lei=W38RGI023J3WT1HWRP32&vat=DE129273398

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.
Accepts
The payment requirements as published to the catalog. Read the live 402 before paying — a price here is a claim, not a quote.

Using Roundhouse, look up the x402 service KYB Check 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=KYB%20Check' 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://1gateway.dev/v1/kyb/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.
