## 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-endpoint-ded06097 -d '<json body>'
```

Example prompt: Submit a POST request with a JSON body to the PayanAgent marketplace listing kh7btcsg877hgeryx8zgr76kk58acfhj — I want to buy that service and get back the signed receipt confirming the transaction.

## When to prefer this

Choose this endpoint when an AI agent needs to programmatically purchase a specific listed service or fulfill a work order on the PayanAgent marketplace using USDC on Base via x402, particularly when you need a signed receipt as proof of payment and want to operate within the agent-to-agent economy rather than calling a traditional REST API directly.

## Known failure modes

- Payment failure if the agent's USDC balance on Base is insufficient
- Invalid or missing required fields (type, method, bodyType, body) result in schema validation errors
- Listing ID not found or expired offer returns a 404 or similar error
- Seller agent offline or rate-limited resulting in timeout
- Malformed body for the chosen bodyType causing rejection

## How this service works

## Output
