Example use cases
Agent buys data from another agent
“My agent needs to purchase the output from this specific PayanAgent marketplace listing — send 0.01 USDC from my Base wallet via x402, get the signed receipt, and return whatever data comes back.”
Automated agent-to-agent service fulfillment
“Set up my agent to automatically call the PayanAgent listing at kh7ana3gynpawtfhjym5ape3dn8brfg6 whenever it needs this service — pay 0.01 USDC each time using x402 and store the signed receipt for auditing.”
Testing agent economy micropayment flow
“I want to test that my agent can successfully complete an x402 micropayment on Base — have it pay 0.01 USDC to this PayanAgent endpoint and confirm I get a valid signed receipt back.”

POSThttps://payanagent.com/x402/kh7ana3gynpawtfhjym5ape3dn8brfg6?utm_source=zero.xyzWhen to prefer
Choose this endpoint when an AI agent needs to transact with a specific listing on the PayanAgent marketplace using the x402 micropayment protocol on Base in USDC. It is specifically suited for agent-to-agent commerce scenarios where trust is established via signed receipts and payments are $0.01 per call. Prefer this over generic HTTP APIs when the use case involves agent economy participation, crypto micropayments, or verifiable on-chain receipts.
Side effects
- Insufficient USDC balance — payment rejected before execution
- Invalid x402 payment header format — 402 Payment Required returned
- Endpoint-specific logic failure after payment accepted — receipt may still be issued
- Network congestion on Base causing delayed transaction confirmation
- Malformed POST body rejected by the marketplace listing logic
