Api Endpoint

effectguard-x402-experiment.onrender.com

Coordinate agents sharing one account: reuse matching JSON reads within 30 seconds, or stop duplicate operations using a stable business event ID. Enroll once at /v1/enroll, then authenticate paid calls with your Bearer key. After EXECUTE use /v1/start and /v1/commit around your own tool. Same-request payment recovery is free. Integration and cost measurement: /agent. External execution is not guaranteed exactly once.
