# API Overview

This section is focused on 2 groups of people:

* Developers who want to build their own products on top of Echo Extension.

### Pre-requisites

<Tip>
  Before you start, you need to obtain the [Extension-Token](/activation)
</Tip>

### Endpoints

<Danger>
  Each endpoint has a 100 req / 10 sec rate-limit. Any attempt to spam / DDOS the endpoint will result in permanent ban without an ability to use Echo products in the future

<Tip>
  There is no CDN endpoint right now - use the endpoint with the closest latency in order to achieve the best speed
