## 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 agent-exchange-directory-listing-paid-7-day-680d9a12 -d '<json body>'
```

Example prompt: List my x402 endpoint at https://api.myservice.com/data in the Agent Exchange public directory under the name 'MyDataAPI' with description 'Real-time sports scores for AI agents' — pay the $1 USDC listing fee.

## When to prefer this

Use this endpoint when you want to make an x402-protocol API discoverable to AI agents and developers browsing the Agent Exchange public directory. It is the canonical submission endpoint for the Agent Exchange marketplace and requires no account — just a $1 USDC payment on Base. Prefer this over manual outreach or other directories when your target audience is AI agents or agent builders looking for machine-payable APIs.

## Known failure modes

- Payment of $1 USDC on Base fails or is insufficient — listing is rejected
- URL field is missing or malformed — 400 Bad Request
- payTo address is invalid Ethereum address — validation error
- Duplicate URL submitted — may create duplicate or overwrite existing listing
- Network or Base chain congestion causes payment timeout

## How this service works

Pay $1 USDC on Base to list your x402 endpoint in the public Agent Exchange directory. GET /directory is free. Body: { url, name?, description?, payTo? }. No account. Listing is live immediately and expires in 7 days unless renewed.

## Output

A confirmation that the listing is live in the Agent Exchange public directory, along with the listing ID and expiry timestamp (7 days from submission). The endpoint is immediately discoverable via GET /directory.
