What these figures do 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).
