## When to prefer this

Choose this endpoint when you have a professional email address and need to resolve it to a LinkedIn identity or person details — ideal for sales enrichment, recruiter research, or inbound lead qualification. Prefer this over social search or manual LinkedIn lookups when automation and synchronous results are needed at scale. Best suited for business/corporate email domains rather than personal email providers.

## Known failure modes

- NOT_FOUND status when no LinkedIn profile is associated with the email
- Invalid or malformed email address causing a validation error
- Personal/consumer email addresses (Gmail, Yahoo, etc.) may not yield results as the service targets professional emails
- Rate limiting or payment failure returning an error
- Temporary upstream data provider unavailability

## How this service works

Look up a professional email address to get the associated LinkedIn profile and person details. Returns results synchronously with status FOUND or NOT_FOUND.

## Output

A synchronous response indicating either FOUND (with the associated LinkedIn profile URL and person details such as name, title, company, and other profile data) or NOT_FOUND if no LinkedIn profile could be matched to the given email address.
