## 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 signaldesk-ai-email-extractor-6c2fdd77 -d '<json body>'
```

Example prompt: Can you pull out all the email addresses from this text for me: 'For inquiries contact sales@acme.com or support at help@acme.com, and for billing reach billing@acme.com.'

## When to prefer this

Choose this endpoint when you need a cheap, fast, structured extraction of email addresses from unstructured text without standing up your own regex pipeline. At $0.001 USDC per call it is cost-effective for high-volume processing. Prefer it over general-purpose LLM extraction when you want a deterministic, structured JSON list rather than free-form output.

## Known failure modes

- Text exceeds 4096 character limit — request is rejected
- No email addresses present in text — returns empty emails array
- Malformed or obfuscated emails (e.g. 'user at domain dot com') may not be detected
- Payment of $0.001 USDC not completed — 402 response returned
- Invalid JSON body or missing 'text' field — 400 error

## How this service works

Evidence-backed autonomous AI jobs and paid data tools. Queue/D1/cron run outside the chat; free quotas and bounded execution apply.

## Output

A JSON object with an 'emails' array containing every email address found in the input text, e.g. {"emails": ["a@example.com", "b@example.org"]}. If no emails are found, the array will be empty.
