gapfill
Sanctions and export-control screening of up to 100 names in one call, $0.002 a name, settled as one payment: OFAC SDN and non-SDN, US export lists, UN, EU and UK, with fuzzy matching, score, matched alias, programmes and birth dates per match. For KYC, AML and counterparty checks over customer or supplier lists. All or nothing: if any name can't be screened, nothing is charged and each failure is named.

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.

Show the promptHide the prompt
Using Roundhouse, look up the x402 service gapfill 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=gapfill' 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://jotowl.com/v1/sanctions/screen/batch, 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.
