# AdGuard Home OpenAPI We are using [OpenAPI specification](https://swagger.io/docs/specification/about/) to generate AdGuard Home API specification. ## How to edit the API spec The easiest way would be to use [Swagger Editor](http://editor.swagger.io/) and just copy/paste the YAML file there. ## How to read the API doc 1. `yarn install` 2. `yarn start` 3. open `http://localhost:4000/` ## Changelog [Here](CHANGELOG.md) we keep track of all non-compatible changes that are being made. ## Authentication If AdGuard Home’s web user is password-protected, a web client must use authentication mechanism when sending requests to server. Basic access authentication is the most simple method: a client must pass `Authorization` HTTP header along with all requests: ```http Authorization: Basic BASE64_DATA ``` Where `BASE64_DATA` is base64-encoded data for `username:password` string.
