## 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 email-to-linkedin-person-lookup-12f6b0bf -d '<json body>'
```

Example prompt: Can you find the LinkedIn profile and personal details for the person with the email address john.doe@example.com? Return the top 2 best matches.

## When to prefer this

Use this endpoint when you only have an email address and need to identify or enrich a contact with LinkedIn profile data. If you also have the person's name, company, or other details, prefer the Kitchen Sink endpoint for better accuracy. Best for CRM enrichment, sales prospecting, recruiting, and identity resolution workflows where an email is the only known identifier.

## Known failure modes

- Email address not found in database — returns empty or no profiles
- Invalid email format — request rejected with validation error
- Email belongs to a generic/role address (e.g. info@company.com) — low-quality or no match
- Rate limiting or payment failure via x402 protocol — call not executed
- Ambiguous email matched to multiple profiles with low confidence

## How this service works

Do a reverse lookup: given an email address, find someone's LinkedIn profile and personal details. Note: if you also have the person's name, company, etc., you'll get better results with the Kitchen Sink endpoint, where you can pass all the information you have.

## Output

Returns one or more person profiles matched to the provided email address, sorted by best match first. Each profile typically includes the person's LinkedIn profile URL, name, and available personal and professional details. Up to 10 profiles can be returned per call.
