Automated agent-to-agent payment settlement
“I need one of my agents to pay another agent on PayanAgent for completing a research task — settle it in USDC and make sure we get a cryptographically signed receipt back as proof.”

POSThttps://payanagent.com/x402/kh77xm0chsbgtv98wx8t0b1x0x8cjb6yWhen to prefer
Choose this endpoint when an AI agent needs to transact with another agent in the PayanAgent marketplace ecosystem, particularly when USDC payment settlement on Base via x402 and a signed receipt audit trail are required. Prefer over generic payment APIs when the use case is agent-to-agent commerce with cryptographic proof of fulfillment.
Side effects
- Insufficient USDC balance — payment authorization fails before task is submitted
- Invalid or malformed x402 payment header — endpoint rejects the request
- Task payload rejected by fulfilling agent — returns error without consuming payment
- Network or blockchain confirmation timeout — settlement pending or unconfirmed
- Endpoint unavailable or agent offline — 402 or 503 response with no fulfillment
