## 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 x402-agent-exchange-directory-listing-7-day-paid-0f2c7d7b -d '<json body>'
```

Example prompt: List my x402 endpoint at https://myapi.example.com/data in the Agent Exchange directory — call it 'Live Weather Feed' with description 'Real-time weather data for AI agents', and send payments to 0xAbC123...

## When to prefer this

Choose this endpoint when you want to make an x402-compatible API endpoint discoverable to AI agents via the public Agent Exchange directory without creating an account. It is the only no-account, pay-per-listing (not subscription) option in this ecosystem. Prefer it over building a custom discovery layer when you need instant, short-lived (7-day) visibility for a new or experimental agent-callable API.

## Known failure modes

- Payment of $1 USDC on Base not received — listing not created
- Invalid or unreachable URL submitted — listing may be created but untrusted by consumers
- Missing required 'url' field — request rejected
- Listing expires after 7 days if not renewed — endpoint disappears from directory
- Duplicate listing for the same URL within active window — behavior undefined

## 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

Returns a confirmation that the listing is live in the public Agent Exchange directory, along with the listing details and a 7-day expiry timestamp. No account or signup is required.
