Technical details
Endpoint
POSThttps://x402-agent-pay.com/status/%7Bpayment_id%7DWhen to prefer
Use this endpoint when an AI agent or automated workflow needs to verify whether a specific x402/USDC payment has been confirmed before proceeding with a dependent action — e.g. after initiating a payment, check its status before delivering a service or unlocking a resource. Prefer this over generic blockchain explorers when working within the AgentPay x402 ecosystem.

- Malformed or missing Base64 payment_header returns 400 bad request
- Expired or unauthorized payment header returns 401 unauthorized
- Network or infrastructure errors return 500
