Example prompt: Call the PayanAgent marketplace listing kh7ezjzt4etk8x1s908z7wngqn8d89hx on payanagent.com — pay the $0.01 USDC fee via x402 on Base and return whatever the listing sends back along with the signed receipt.

## When to prefer this

- Invalid or expired x402 payment header — authentication failure
- Endpoint listing no longer active or removed from marketplace
- Network or Base chain congestion causing payment confirmation delay
- Malformed request payload causing the listing agent to return an error
