## 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 bytemine-email-finder-12e68dfc -d '<json body>'
```

Example prompt: Can you find the work email for Sarah Chen at acme.com? Try her LinkedIn too if needed: linkedin.com/in/sarahchen.

## When to prefer this

Use this endpoint when you need a single, deliverable work email for a known person at a specific company and want SMTP-verified accuracy rather than a raw guess. Prefer it over bulk email finders when precision matters and you are billed only on confirmed finds. It is especially useful when you have a LinkedIn URL and want automatic name and domain resolution without pre-formatting inputs.

## Known failure modes

- No email found if the person does not exist at the domain or patterns cannot be verified
- Catch-all domain detection may limit confidence — email returned as risky rather than verified
- Invalid or non-existent LinkedIn URL causes resolution failure
- Missing required fields (no company_domain and no linkedin_url) returns a validation error
- SMTP probing may be blocked by strict mail servers, reducing deliverability confidence

## How this service works

Find the most likely deliverable work email for a person. Provide first_name, last_name, and company_domain, or a LinkedIn person or company URL and the identity is resolved automatically. Builds ranked candidate patterns and probes them over SMTP, with catch all detection. Results are cached per name and domain so repeat lookups are instant and free. Billed only on status found.

## Output

Returns the most likely deliverable work email address for the person, along with a deliverability status (e.g. found, risky, catch-all, invalid) and confidence ranking. Results are cached per name and domain for instant repeat lookups. Billing only occurs when status is 'found'.
