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 1 day (less than 30).
