## 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 api-zeroclick-ac-zero-register-smoke-7299d4d-ac6ffa84 -d '<json body>'
```

Example prompt: Run the ZeroClick Zero-register smoke test with the message 'hello registration check' so I can confirm the registration pipeline is live.

## When to prefer this

Use this endpoint exclusively when you need to confirm that the ZeroClick-to-Zero registration and publish pipeline is operational. This is a smoke/test endpoint, not suitable for any real buyer-facing tasks or production workflows.

## Known failure modes

- Upstream echo service unavailable — the endpoint returns an error if the backing echo service is down
- Payment authorization missing — request rejected if the x402 payment of 0.01 USDC is not provided
- Malformed request body — if the JSON does not conform to the expected schema (no extra properties allowed), the endpoint may return a validation error

## How this service works

Use this only to verify ZeroClick to Zero registration. Send JSON with an optional message string.

Use when: Checking whether Zero registration from ZeroClick publish is working

Do not use when: Real buyer tasks

Failure modes: Upstream echo service unavailable; Payment authorization missing

Price: 0.01 USDC per request.

## Output
