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-4802bf59 -d '<json body>'
```

Example prompt: Can you run a quick smoke test on my ZeroClick Zero registration to make sure it's working — send a test message like 'hello smoke test' to confirm the registration flow is live?

## When to prefer this

Use this endpoint exclusively when you need to confirm that the ZeroClick-to-Zero service registration pipeline is functioning. Do not use for any real buyer transactions or production workflows — it is strictly a developer smoke test.
