- What this proves. The payment rail settles end to end: a 402 challenge, an external wallet paying it, a facilitator verifying it, data delivered, and the money landing with us. Buyers do not have to trust our description of that path; the hashes are the description.
- What this does not prove. It is not organic revenue and not a sales volume claim. Eight verification payments from one marketplace's wallet is the honest size of the number, and it is the number we are showing.
- Machine-readable. The same rows are in /.well-known/x402 under
settlements, and the per-route prices in the OpenAPI document.
