Is this x402 seller actually paid, compared with every other one? One row out of our weekly read of every seller on Base, where all of them get the SAME window, so the number means the same thing seller to seller. Give a payTo address: verdict (paid, single-payer, self-funded, dust-only, silent), payers, how many the seller itself funded, USDC in. Call counts are not payments; of 1 397 sellers read both ways, 312 are called and paid nothing.

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.
