## 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 tomba-email-finder-via-x402-orthogonal-com-7af8c327

## When to prefer this

Use this endpoint when you have a person's name and their employer's domain and need to find their most likely professional email address for outreach or contact purposes. Prefer this over email format endpoints (which return patterns, not individual emails) when you need a specific person's address. It complements phone validation or domain email pattern lookups when building a full contact profile.

## Known failure modes

- Email not found — person may not be indexed or domain may not have known patterns
- Low confidence score — returned email may be a best guess and could bounce
- Invalid domain format — domain must be a valid hostname like stripe.com
- Company name too short or too long — must be between 3 and 75 characters
- Rate limiting or payment failure due to x402 protocol issues
- Person exists but uses a non-standard email format not captured by Tomba's patterns

## How this service works

Find the most likely email address from a domain name, first name, and last name.

## Output

Returns the most likely professional email address for the given person at the specified domain, along with a confidence score indicating how certain the prediction is. Optionally includes a phone number if enrich_mobile is set to true.
