"index": 0,
"message": {
"content": "Based on the image provided, this is a technical documentation page titled **"Authentication"** for an API service called **maxtoken**. It guides developers on how to securely access and use the API. Here is a breakdown of the specific sections contained in the file: **1. API Key Authentication** * It explains that the maxtoken API uses **Bearer token authentication**. * All requests must include the API key in the header. **2. Getting Your API Key** * Provides a step-by-step guide: 1. Sign up at `https://maxtoken.io/doc`. 2. Navigate to the API Keys section in the dashboard. 3. Generate a new key. 4. Copy and store it securely. * **Security Warning:** It explicitly warns users to keep keys secure, not to commit them to version control, and to rotate them regularly. **3. Making Authenticated Requests** * Shows how to structure the HTTP header: `x-api-key: Bearer YOUR_API_KEY`. * Provides a **cURL** code snippet demonstrating a POST request to `https://api.maxtoken.io/v1/chat/completions` using the model "gpt-4o". **4. Environment Variables** * **Recommended Setup:** Advises storing keys in environment variables (e.g., `export API_KEY="..."`) rather than hardcoding them. * **Using .env Files:** Shows a Python code example using `python-dotenv` to load credentials securely. * **Warning:** Reminds users to add `.env` files to `.gitignore` to prevent leaking secrets. **5. Authentication Errors** * Lists common HTTP error codes and their JSON response formats: * **401 Unauthorized:** Key is missing or invalid. * **403 Forbidden:** Key doesn't have permission for the resource. * **429 Too Many Requests:** Rate limit exceeded. **6. Best Practices** * Lists expandable sections for maintaining security, such as "Implement Key Rotation," "Use Different Keys for Different Environments," and "Monitor Usage." **7. API Key Management** * **Generating New Keys:** Instructions on how to create descriptive keys via the dashboard. It notes you can only copy the key once. * **Revoking Keys:** Steps to revoke a compromised key and update applications. **8. Support** * Troubleshooting tips for authentication issues. * Provides a contact email for help: `jacoblam3219@gmail.com`.",
