The endpoint
A LinkedIn URL in, a US direct dial out
The phone enrichment API takes a LinkedIn profile URL and returns the person's direct phone number, mobile or direct line, when one is found. Coverage is the United States only, and phone endpoints come with every paid plan, from Start. Run Email Enrichment on the same URL to reach a contact by call and by email.
