ContactOut API

REST API for B2B contact data: enrich LinkedIn profiles and email addresses with verified work and personal emails, phone numbers and profile details; search and count people by criteria; search companies and enrich domains; find decision makers; check whether an email or phone exists for a profile without revealing it; verify email deliverability singly or in batch (with a webhook callback); manage outreach campaigns; and read API usage stats and remaining credits. Authenticated with an API token header; credit-metered per result.
