## Getting Started

### Base URL

<Tabs>
  <Tab title="Langdock Cloud">
    For standard Langdock Cloud users, use the following base URL for all API requests:

    ```
    https://api.langdock.com
    ```
  </Tab>

  <Tab title="Dedicated Deployment">
    If your organization uses a dedicated Langdock deployment (custom domain), your base URL follows this pattern:

    ```
    https://<your-domain>/api/public
    ```

    For example, if your Langdock instance is at `https://langdock.yourcompany.com`, the API base URL would be:

    ```
    https://langdock.yourcompany.com/api/public
    ```

    <Warning>
      **Common mistake:** Don't forget the `/api/public` prefix when using a dedicated deployment. Using just your domain without this prefix will result in authentication errors or redirects.
    </Warning>
  </Tab>
</Tabs>

### Authentication

All API requests require authentication using a Bearer token:

```bash theme={null}
curl -H "Authorization: Bearer YOUR_API_KEY" \
  https://api.langdock.com/openai/eu/v1/chat/completions
```

**Security Note:**

<Info>
  Langdock intentionally blocks browser-origin requests to protect your API key and ensure your applications remain secure. Calling the API from the browser (e.g., from JavaScript running in a web page) exposes the Langdock API Key publicly and creates a security risk. Therefore, the Langdock API must be accessed from a secure backend environment. For more information, please see our guide on [API Key Best Practices](/en/admin/ai-adoption-and-rollout/best-practices/api-key-best-practices).
</Info>

### Rate Limits

API requests are subject to rate limiting to ensure fair usage and system stability. Rate limits are applied **per model**. The default limits are **500 RPM** (requests per minute) and **60,000 TPM** (tokens per minute). If you consistently hit these limits, reach out to our support team to discuss an increase in rate limits.

For **BYOK workspaces**, admins can configure custom limits per model in **Settings > Models**.
