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.
Example use cases
Sales lead enrichment from email
“I have a lead's email address — j.smith@acmecorp.com — can you find their LinkedIn profile and personal details so I can personalize my outreach?”
Identify unknown email sender
“Someone emailed me from contact@techstartup.io and I don't know who they are. Can you do a reverse lookup to find their LinkedIn profile and name?”
Recruiting candidate verification
“I have a candidate's email — sara.jones@gmail.com — can you pull up their LinkedIn profile so I can verify their background before the interview?”

Endpoint
POSThttps://x402.orthogonal.com/fiber/v1/email-to-person/singleWhen to prefer
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.
Side effects
- 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
