## 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`):

Example prompt: Can you find the LinkedIn profile associated with john.smith@acmecorp.com — I'd like the full profile data including their job title and company?

## When to prefer this

Use this endpoint when you have an email address and need to identify the person's LinkedIn profile or professional background. Ideal for B2B sales enrichment, recruitment pipelines, CRM contact enrichment, and lead qualification workflows where you start with an email and need professional identity data. Prefer the basic (1-credit) mode when you only need the LinkedIn URL; use with_profile=true when you need structured professional data like title and employer.

## Known failure modes

- Email not found in database — returns no match or empty result
- Email exists but has no associated LinkedIn profile
- LinkedIn profile found but is private or incomplete, limiting returned metadata
- Invalid email format provided — validation error
- Rate limiting or credit exhaustion causing request failure

## How this service works

Find a LinkedIn profile from an email address. 1 credit without profile data, 2 credits with profile data (with_profile=true).

## Output

Returns the LinkedIn profile URL linked to the provided email address. When with_profile=true, also returns full profile metadata such as name, current job title, employer, location, and other professional details available on LinkedIn. Credits consumed vary: 1 credit for URL only, 2 credits with full profile data.
