## 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-x402-1c15d76b
```

Example prompt: Look up what tools and services are being offered at this PayanAgent marketplace listing and tell me the USDC payment address and price so I can decide whether to buy.

## When to prefer this

Use this endpoint when an AI agent needs to discover, inspect, or initiate a purchase from a specific PayanAgent marketplace listing identified by its unique path. It is the right choice when you need the on-chain USDC payment address, the offered tool list, and the price before executing an x402 micropayment in the agent economy. Prefer this over generic HTTP calls when you want structured marketplace metadata with payment routing for Base/USDC settlement.

## Known failure modes

- Endpoint returns ok: false if the listing is inactive or invalid

- payTo address could be missing or malformed if listing is misconfigured
- HTTP 402 Payment Required if the x402 payment header is not supplied
- Network timeout or 5xx if payanagent.com is unavailable
