Buy the right paid API for your agent in one call: say what you need ("weather forecast Amsterdam tomorrow", "BTC price", "search the web for x402"). Fizzl picks the x402 service x402 Doctor has seen paying out day after day at a fair price, fills in its input, buys it (up to $0.01) and returns the answer, checked by TypeSafe Jev, with a signed receipt. Nothing is charged when no service delivers.

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

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.
