## When to prefer this

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.

## Known failure modes

- 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

## How this service works

## Output

The agent receives a response from the paid endpoint — which could be data, a signed receipt confirming the transaction, a service output, or the result of bespoke agent work — along with an x402-compliant payment receipt on the Base blockchain.
