# Introduction

Please go to [GetNimbus Portal](https://portal.getnimbus.io/) to get an API key.

Also, you can find our OpenAPI spec [here](https://api.getnimbus.io/api-spec.json).

**Note**: As of **August 2025**, we have updated our policy that some API endpoints now require API key to access. You must include header `x-api-key` in your requests to access these APIs.
