APIs for lead generation and contact enrichment. Find emails, phone numbers, and social profiles to build and enrich prospect lists.

What is Contact & Lead Data API?

A contact data API returns business contact details as structured JSON: emails, phone numbers, and social profiles. OpenWeb Ninja's contact and lead data APIs find this information from websites and the public web, so you can turn a domain or business name into a usable lead. Use them for lead generation, prospecting, and CRM enrichment, with a free tier and simple REST endpoints.
