## 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 contactout-person-from-email-lookup-a6a5fbfb -d '<json body>'
```

Example prompt: Who is the person behind j.smith@acmecorp.com? Pull their full name, current title, company, LinkedIn URL, and any work history you can find.

## When to prefer this

Use this endpoint when you have an email address and need to identify the professional identity behind it — especially for inbound signups, cold email replies, or lead enrichment. Prefer this over LinkedIn-first lookups when the email is your only starting point. It complements the reverse direction (LinkedIn-to-email) offered by contactout/linkedin-contacts.

## Known failure modes

- Email not found in ContactOut database — returns empty or null profile
- Invalid email format — schema validation error before request is made
- Personal email with no professional data attached — partial or empty result
- Rate limiting or quota exhaustion — HTTP 429 or payment-related error
- Network timeout if ContactOut upstream is slow — HTTP 5xx

## How this service works

Reverse-enrich an email address into a full person profile via ContactOut: name, current title/company, LinkedIn URL, work history. Pass `email` (work or personal). Use it to identify an inbound signup or reply before responding. Complements contactout/linkedin-contacts (which goes the other direction).

## Output

Returns a structured person profile sourced from ContactOut, including the individual's full name, current job title, current employer, LinkedIn profile URL, and professional work history entries — all derived from a single email address input.
