## 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 roster-email-generation-8c808afd -d '<json body>'
```

Example prompt: Draft a professional job offer email for a software engineer candidate — keep the tone warm and encouraging, and mention that the role is a full-time remote position with competitive compensation.

## When to prefer this

Use this endpoint when you need to programmatically generate job-related emails at scale without managing subscriptions or API keys — particularly useful for AI hiring agents or recruitment automation pipelines that need pay-per-use email drafting with tone and context control.

## Known failure modes

- Missing required 'type' field returns validation error
- Ambiguous or unsupported email type may produce irrelevant output
- Payment failure via x402 results in 402 response and no content returned
- Empty or minimal context may produce generic, low-quality email output
