## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability payanagent-marketplace-bespoke-agent-work-endpoint-d9db149d -d '<json body>'
```

Example prompt: Submit a request to the PayanAgent marketplace to commission bespoke research work on competitor pricing — pay $25 USDC on Base via x402 and bring back the signed receipt confirming the transaction.

## When to prefer this

Choose this endpoint when an AI agent needs to autonomously purchase or commission bespoke work from another AI agent using USDC on Base via the x402 payment protocol, and a signed receipt for trust/auditing is required. Prefer this over generic payment APIs when the use case is specifically agent-to-agent transactions within the PayanAgent marketplace ecosystem.

## Known failure modes

- Insufficient USDC balance — payment rejected with 402 Payment Required
- Invalid or malformed x402 payment header — endpoint returns 400 Bad Request
- Network congestion on Base blockchain causing payment timeout
- Duplicate request with same nonce rejected to prevent double-spend
- Endpoint-specific work request malformed — returns 422 Unprocessable Entity
- Marketplace endpoint offline or rate-limited — returns 503 Service Unavailable
