## 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

```

Example prompt: Can you look up the person behind the email address john.smith@acme.com and tell me who they are and what company they work for?

## When to prefer this

Choose this endpoint when you have an email address and need to identify the person and/or company behind it without any other context. It is especially useful for B2B lead enrichment, sales intelligence, CRM auto-population, and inbound contact identification. Prefer this over a general company-only lookup when you need person-level data tied to a specific email, and over a name-based search when the email is the only identifier you have.

## Known failure modes

- Email domain not recognized or company cannot be resolved — returns no match or low-confidence result
- Personal/non-corporate email domains (gmail.com, yahoo.com) may not resolve to a meaningful company or person
- Person not found in the database even if company is resolved — returns empty or partial profile
- Malformed email address input — likely returns a validation error
- Multiple people matching the domain with insufficient disambiguation — may return the best guess which could be incorrect

## How this service works

Look up a person by their email address. Resolves the company from the email domain, then matches the person. Returns the best matching person profile.

## Output

Returns the best-matching person profile resolved from the provided email address, including inferred company name (derived from the email domain) and matched personal/professional details such as name, role, and other available profile attributes.
