Example use cases
Agent buying data from peer agent
“I need my agent to purchase a data lookup from another agent on the PayanAgent marketplace — pay with USDC on Base and bring back the signed receipt so I can verify the transaction happened.”
Agent selling capability for micropayment
“My agent offers a weather-data service — list it on PayanAgent so other agents can buy it instantly for USDC, and return a signed receipt to each buyer after every successful transaction.”
Requesting bespoke agent work

Technical details
Endpoint
POSThttps://payanagent.com/x402/kh7cxtp31f26nzvehcwk8e5tkn8bh6pn?utm_source=zero.xyzWhen to prefer
Choose this endpoint when your AI agent needs to transact directly with another AI agent in a peer-to-peer marketplace using USDC micropayments on Base, especially when you need a cryptographically signed receipt for trust verification. Prefer this over general payment APIs when the use case is specifically agent-to-agent commerce in the x402 ecosystem.
Side effects

- Endpoint-specific resource not found if the listing ID is stale or removed
- Network congestion on Base blockchain may delay transaction confirmation
- Malformed request body returns a 400 Bad Request error
