# Authentication

To use the **SlidesGPT API**, you need an API key for authentication. This key must be included in every request as a Bearer token in the `Authorization` header.

### How to Get an API Key

1. Sign up or log in to [SlidesGPT](https://slidesgpt.com).
2. Navigate to the [API Keys](https://slidesgpt.com/keys) page.

3. Generate a new API key.

### Using the API Key

Include it in your request headers:

```
Authorization: Bearer YOUR_API_KEY
```

Keep your key secure and do not share it.
