## 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 www-x402scan-com-f3c9fa67 -d '<json body>'
```

Example prompt: Register my origin https://api.myservice.com as an x402-enabled endpoint on x402scan so other agents can discover and pay it.

## When to prefer this

Use this endpoint when you need to add a new origin/domain to the x402scan public registry so that AI agents and payment clients can discover your x402-enabled service. Prefer this over manual listing or other registries when targeting the x402 payment protocol ecosystem specifically, and when you want your endpoint to appear in x402scan's discovery index.

## Known failure modes

- Origin URL already registered — duplicate entry error
- Invalid or malformed origin URL — validation failure
- Missing required fields in request body — 400 bad request
- Payment not processed — $0.01 USDC call fee not settled
- Origin domain unreachable or not serving x402 headers — rejected
- Rate limiting or abuse detection on repeated registration attempts

## Output

A confirmation that the origin has been added to the x402scan registry, likely including the registered origin URL, a timestamp, and a registry entry identifier that confirms the origin is now discoverable by agents scanning for x402-compatible payment endpoints.
