# Introduction

> Learn how to start using Permutive's APIs

Permutive's APIs allow media owners to collect, enrich, resolve, and segment their data in real-time, and to programmatically manage their Permutive account.

For processing end-user data, our APIs are typically called via the various [SDKs](/sdks) Permutive offers for different environments, but customers are also free to directly interact with our APIs.

Get started with Permutive's APIs by heading to [authentication](./authentication) and setting up an API key.

## Endpoints

There are six primary Permutive APIs. They are broadly categorized into two groups:

1. **Real-time APIs**: Capture end-user actions on your sites & apps, register & resolve identities, perform segmentation, and retrieve contextual cohorts for a page.
2. **Management APIs**: Programmatically manage cohorts and second-party data taxonomies in your Permutive account.
