## 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-18febac-38f86a82 -d '<json body>'
```

Example prompt: Run a smoke test on the ZeroClick Zero registration endpoint to confirm the publish registration is working — send it a test message like 'hello smoke test'.

## When to prefer this

Use this endpoint exclusively when verifying that the ZeroClick to Zero registration pipeline is operational; it is a smoke/test endpoint not intended for production buyer workflows or real data processing.

## Known failure modes

- Upstream echo service unavailable — registration check cannot complete
- Payment authorization missing — request rejected before processing
- Malformed JSON input — request body fails schema validation
- Network timeout — endpoint unreachable

## 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
