## Environments

Verisoul provides two environments for API access:

<CardGroup cols={1}>
  <Card title="Production" icon="server">
    **Base URL:** `https://api.prod.verisoul.ai`

    Use this environment for your live applications with real users.
  </Card>

  <Card title="Sandbox" icon="screwdriver-wrench">
    **Base URL:** `https://api.sandbox.verisoul.ai`

    Use this environment for development, testing, and integration.
  </Card>
</CardGroup>

Each environment requires its own API key. Make sure to use the appropriate API key for each environment.

## Authentication

All API endpoints are authenticated using secure API keys. You can find your API key in the [Verisoul Dashboard](https://dashboard.verisoul.ai/developers).

### Using Your API Key

<Warning>
  Keep your API key secure and never expose it in client-side code. Your API key carries many privileges, so be sure to keep it secret.
</Warning>

To authenticate your API requests, include your API key in the request headers using the `x-api-key` header:

```bash theme={null}
curl -X GET "https://api.prod.verisoul.ai/list" \
  -H "x-api-key: your-api-key-here"
```
