## 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 agents-bytemine-ai-find-a-work-email-9e0a4319 -d '<json body>'
```

Example prompt: Can you find the work email for Sarah Chen who works at acme.com? I need a verified, deliverable address I can use for outreach.

## When to prefer this

Choose this endpoint when you need a single verified work email for a named individual at a known company domain, especially for B2B outreach or CRM enrichment. It is preferable over generic email-guessing tools because it performs live SMTP verification with catch-all detection, caches results so repeat lookups are free, and charges only on a confirmed find. Use it when you have a person's name plus a company domain or LinkedIn URL and need the highest-confidence deliverable address available.

## Known failure modes

- status: not_found — no matching email pattern could be verified for the given name and domain
- status: no_mx — the company domain has no valid MX records, so email cannot be delivered
- status: skipped — input was incomplete or the domain was blocked
- SMTP result: catch-all — domain accepts all addresses so deliverability cannot be confirmed
- Missing required fields — must provide either (first_name + last_name + company_domain) or a linkedin_url
- Invalid LinkedIn URL format — person URL required for automatic identity resolution

## How this service works

Find and validate a work email from a name plus company domain.

## Output

Returns the best candidate email address along with a status (found, guessed, not_found, skipped, or no_mx), a confidence level (high, medium, or low), SMTP verification result (valid, catch-all, or unknown), a catch_all boolean flag, a cached boolean indicating whether the result came from cache, and a credits_charged integer (1 if found, 0 otherwise).
