0x2880EdfFF13100677Bf97A3CBdF3Bc34771C4E5EThe 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.

"description": "Takes a transcript as text, a public URL or inline base64 and returns what follows from the meeting: the tasks, who is responsible, by when, the decisions that were actually taken, and the questions that stayed open. Every single entry carries the verbatim passage it was drawn from, and that passage is looked up in the transcript before the answer goes out — an exact match or a match after whitespace is normalised. Anything that cannot be located is returned flagged as unverified and counted separately, because an invented task in a set of minutes is only noticed once somebody has failed to do it. Where the transcript does not name a responsible person, the field stays empty instead of being filled with the nearest name. Relative deadlines are only turned into dates when a reference_date is supplied, and then only for unambiguous phrases such as today, tomorrow, end of the month or a named weekday, with the rule that was applied returned alongside; everything else keeps the wording as it fell and is marked unresolved. The transcript is processed by a third-party model, and the provider, what leaves this machine and what is retained there are named in every answer — a caller under a confidentiality obligation or a works agreement has to make that call themselves. Nothing is cached, nothing is written to a database, and no part of the transcript appears in any log or error message.",

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. 18 snapshots so far. Verified volume counts only settlements with an on-chain EIP-3009 marker.

Using Roundhouse, look up the x402 service buero.halowerk.com 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=buero.halowerk.com' 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://buero.halowerk.com/v1/meeting-actions, 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.
