x402Check-before-payingScam-checkPreflightVerify-payTo

Check before paying any x402 tool: is this API a scam/safe? Trust-check one seller URL (live 402 + history). Use for verify-payTo, uptime, price/wallet drift, budget guard, validate 402, debug failing settle. Returns ok|caution|avoid + that tool's history only. $0.01/URL. No free tier. Endpoint+history — not wallet OFAC/simulation. Optional deeper signal: GET /preflight/deep ($0.05).

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.
