# API Overview

> Welcome to the DNCScrub API Documentation

Our APIs provide a set of RESTful services for integrating TCPA Compliance, Do-Not-Call Compliance, Call Deliverability, and Data Enhancement directly into your applications. These APIs let you scrub phone numbers against Federal and State DNC lists, maintain Internal DNC and Existing Business Relationship lists, manage your Caller ID, and automate compliance and call deliverability workflows at scale. This documentation will help you understand each API, how they work, and how to integrate them into your dialing platform, CRM, or internal tools.
