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.
