What this evidence does not show
- A passing probe means the endpoint answered an unpaid request with a valid x402 payment challenge on a mainnet network. It does not show that a paid call succeeds or returns useful results.
- Payer and call counts are the registry's own figures, not our measurements.
- The registry's description is not republished.
- Limited evidence: monitored for under 1 day (less than 30).
