                "content": "Based on the image provided, this is a technical documentation page titled **\"Authentication\"** for an API service called **GPTProto**. It guides developers on how to securely access and use the API.\n\nHere is a breakdown of the specific sections contained in the file:\n\n**1. API Key Authentication**\n*   It explains that the GPTProto API uses **Bearer token authentication**.\n*   All requests must include the API key in the header.\n\n**2. Getting Your API Key**\n*   Provides a step-by-step guide:\n    1.  Sign up at `https://gptproto.com`.\n    2.  Navigate to the API Keys section in the dashboard.\n    3.  Generate a new key.\n    4.  Copy and store it securely.\n*   **Security Warning:** It explicitly warns users to keep keys secure, not to commit them to version control, and to rotate them regularly.\n\n**3. Making Authenticated Requests**\n*   Shows how to structure the HTTP header: `Authorization: Bearer YOUR_API_KEY`.\n*   Provides a **cURL** code snippet demonstrating a POST request to `https://gptproto.com/v1/chat/completions` using the model \"gpt-4o\".\n\n**4. Environment Variables**\n*   **Recommended Setup:** Advises storing keys in environment variables (e.g., `export GPTPROTO_API_KEY=\"...\"`) rather than hardcoding them.\n*   **Using .env Files:** Shows a Python code example using `python-dotenv` to load credentials securely.\n*   **Warning:** Reminds users to add `.env` files to `.gitignore` to prevent leaking secrets.\n\n**5. Authentication Errors**\n*   Lists common HTTP error codes and their JSON response formats:\n    *   **401 Unauthorized:** Key is missing or invalid.\n    *   **403 Forbidden:** Key doesn't have permission for the resource.\n    *   **429 Too Many Requests:** Rate limit exceeded.\n\n**6. Best Practices**\n*   Lists expandable sections for maintaining security, such as \"Implement Key Rotation,\" \"Use Different Keys for Different Environments,\" and \"Monitor Usage.\"\n\n**7. API Key Management**\n*   **Generating New Keys:** Instructions on how to create descriptive keys via the dashboard. It notes you can only copy the key once.\n*   **Revoking Keys:** Steps to revoke a compromised key and update applications.\n\n**8. Support**\n*   Troubleshooting tips for authentication issues.\n*   Provides a contact email for help: `[email protected]`.",
