Surfe

Surfe (formerly Leadjet) is a B2B contact-discovery and data-enrichment platform whose REST API turns partial signals - a LinkedIn URL, a name plus a company, a domain, or an email - into verified professional email addresses, mobile phone numbers, company firmographics, and lookalike account recommendations. It is the web-intelligence and contact-discovery layer that sits behind Surfe's LinkedIn and CRM experiences, exposed to developers under https://api.surfe.com/v2 with Bearer API-key auth and a credit-based model. Bulk people and company enrichment run as asynchronous jobs (start with POST, then poll the GET job endpoint or receive a webhook callback). This entry focuses on the contact-discovery, data-enrichment, and B2B/sales-intelligence use cases (people search, people enrichment, company search, company enrichment).

Surfe publishes 4 APIs on the APIs.io network, including Account API, Companies API, People API, and 1 more. Tagged areas include Contact Discovery, Data Enrichment, B2B Data, Sales Intelligence, and Lead Enrichment.

Surfe’s developer surface includes authentication, documentation, engineering blog, and 7 more developer resources.
