Copy the prompt and paste it into Claude, an MCP client or your own agent — it will check 0xb2bd…beef's payment record before paying it over the free read API. No key, no account.

Using Roundhouse, tell me whether this x402 merchant is worth paying: how many distinct
agents have paid it, how recently, and for what.

  Merchant wallet: 0xb2bdc37b8481f4cdcf38402cfcd446ae5133beef

curl -s 'https://api.roundhouseai.io/v0/merchants/0xb2bdc37b8481f4cdcf38402cfcd446ae5133beef'

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.
