Hand this page to an agent

Copy the prompt and paste it into Claude, an MCP client or your own agent — it will find and price a paid API you can call over the free read API. No key, no account.

GET api.roundhouseai.io/v0/endpoints

Verified volume and provider trust are Roundhouse-only signals; activity is settlements to the service's payee wallet over 30 days, 5-day smoothed. 258,895 catalog entries indexed.

Open skill.md
Show the prompt
Using Roundhouse, find x402 endpoints that can do what I need,
tell me what each call costs, and whether the endpoint answered when last probed.

curl -s 'https://api.roundhouseai.io/v0/endpoints?q=<what-you-need>'

Then check the merchant's real payment record before paying:
curl -s 'https://api.roundhouseai.io/v0/merchants/<payTo-wallet>'
Always read the price from the live 402, never from a cached figure.

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.
