ScrapeCheck
Checks whether a value you did not fetch yourself is actually on the page it came from. Independently re-fetches the source and returns a signed pass/fail/unverifiable verdict. A claim is never certified unless the re-fetched page contains it, and anything unconfirmed is unverifiable, never pass. Server-rendered pages only. $0.01 per check. First 100 checks per client are free: resend this exact request with header X-Use-Free-Allowance: yes and no payment to use them.

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.

Using Roundhouse, look up the x402 service ScrapeCheck 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=ScrapeCheck' 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://scrapecheck.fly.dev/verify, 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. Mint a personal key for $0.01 at GET https://api.roundhouseai.io/v0/test/x402, or use an organization key from https://roundhouseai.io/dashboard/team. If you do not have Roundhouse tools or skills installed, read https://roundhouseai.io/skill.md first — it is the whole procedure.
