## 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 person-lookup-enrichment-api-a452c003 -d '<json body>'
```

Example prompt: Can you look up what you can find about jane.doe@acmecorp.com — I want to know her full name, the company she works at, whether that's a real business email, and a confidence score on the result?

## When to prefer this

Choose this endpoint when you need to enrich a contact record using public data signals — especially email-to-person or domain-to-company resolution — without accessing private people databases or social scraping. Ideal for lead enrichment, CRM pre-fill, free-email detection, and lightweight identity resolution where only an email, name, or domain is known.

## Known failure modes

- Low-confidence result when only partial input is provided (e.g. name only with no email or domain)
- No match returned if the email domain is unresolvable or the domain has no public data
- Homepage metadata unavailable if the domain blocks crawling or has no accessible homepage
- Free-email detection may be incomplete for obscure regional providers
- Confidence score near 0 for synthetic or disposable email addresses

## How this service works

Person lookup / person enrichment API (alias of people-enrich). Resolve an email, name, domain, or company into a normalized person record with inferred name, free-email detection, MX records, and optional public company context. Public-data only; no private people databases or social scraping.

## Output
