What this evidence does not show
- A passing probe means the endpoint answered an unpaid request with a valid payment request on a production network (x402 on a mainnet network, or MPP on Tempo mainnet). 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 1 day (less than 30).
