# Authentication

API keys are used to authenticate requests. Create and manage your API keys in [the settings](https://platform.indices.io/api-keys).

We use the [HTTP Bearer authentication](https://swagger.io/docs/specification/v3_0/authentication/bearer-authentication/) scheme. To supply your API key, include the following header in your requests:

```
Authorization: Bearer <API_KEY>
```
