What Is the Seamless.AI API?

The Seamless.AI API gives your team direct, programmatic access to our contact and company data—without using the app interface.

With the API, you can:

  • Search for leads using filters like job title, company size, industry, and location
  • Enrich incomplete records with full, verified contact and company details
  • Sync data directly into your CRM or internal systems automatically

This is ideal for teams looking to scale, automate, or customize lead workflows using Seamless.AI’s real-time data engine.
