## 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 apexapi-ai-email-reply-generator-c8068df8 -d '<json body>'
```

Example prompt: Can you draft a professional reply to this email I received from a client asking about project timelines? The original message says: 'Hi, could you give us an update on where things stand with the Q3 deliverables? We'd like to share a status with our stakeholders by end of week.'
