Is this x402 seller real? One seller's report card before you pay them: what they sell, price, rank of all sellers, rivals, and from the chain who actually pays it on Base: payer wallets, how concentrated they are, how many came back on 2 or more days, and how many of its payers are wide samplers that paid 30+ sellers (not shoppers). Dated, with the evidence behind each fact. $0.001 a call. Refusals are free.

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.
