# Atlas API

## Making requests

Atlas' API follows JSON RPC style convention where each API endpoint is a method on `https://www.beautifulatlas.com/api/<METHOD>`. Each request needs to be made using HTTPS.

Each method can be called with either `GET` or `POST` (recommended). For `GET` requests query string parameters are expected (e.g. `/api/document.info?id=...&token=...`). When making `POST` requests, request parameters are parsed depending on `Content-Type` header. To make a call using JSON payload, one must pass `Content-Type: application/json` header:

```shell
curl 'https://www.beautifulatlas.com/api/documents.info?id=atlas-api-NTpezNwhUP'\
  -H 'authorization: Bearer <API KEY>'\
  -H 'content-type: application/json'\
  -H 'accept: application/json'
```

## Authentication

To access private API endpoints, you must provide a valid API key. You can create new API keys in your [account settings](https://www.beautifulatlas.com/settings). Be careful when handling your keys as they give access to all of your documents.

To authenticate with Atlas API, you can supply the API key as a header (`Authorization: Bearer <API KEY>`) or as part of the payload using `token` parameter.

Some API endpoints allow unauhenticated requests for public resources and they can be called without an API key.

## Errors

All successful API requests will be returned with `200` status code and `ok: true` in the response payload. If there's an error while making the request, appropriate status code is returned with the `error` message:

```json
{
	"ok": false,
    "error: "Not Found"
}
```
