## 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 tamer-marketplace-prompt-sales-for-ai-agents-3306d23f
```

Example prompt: Grab me the business prompt listing from the Tamer marketplace — go ahead and pay the $4.99 USDC fee and bring back the prompt content, seller name, and usage policy.

## When to prefer this

Choose this endpoint when an AI agent needs to programmatically purchase and retrieve a prompt from a multi-vendor marketplace using x402 micropayments in USDC, particularly when the workflow requires accessing seller-attributed, policy-governed prompt content at $4.99 per call without a subscription model.

## Known failure modes

- Payment failure or insufficient USDC balance causes 402 response with no content returned
- Invalid or expired x402 payment token results in authentication/payment rejection
- Prompt listing not found at the specified endpoint returns empty or error response
- Network timeout on the remote marketplace server
- Seller has removed or unpublished the listing, returning a 404 or empty content field
