API Documentation

Introduction

Welcome to the API documentation. This API provides access to user data and related functionalities. You can retrieve, create, update, and delete user records through this interface.

Our API follows RESTful principles and uses JSON for request and response bodies. All requests should be made over HTTPS.

Authentication

Authentication is handled via API keys. Include your API key in the Authorization header of every request:

Authorization: Bearer YOUR_API_KEY

Requests without valid authentication will receive a 401 Unauthorized response.

Error Handling

The API uses standard HTTP status codes to indicate the success or failure of a request. Error responses will typically include a JSON object with an error message and often more specific details.

• 2xx: Success
• 4xx: Client Error (e.g., invalid request, unauthorized)
• 5xx: Server Error

Common error codes include:

• 400 Bad Request: The request was malformed or contained invalid data.
• 401 Unauthorized: Authentication credentials were missing or invalid.
• 403 Forbidden: The authenticated user does not have permission to perform the action.
• 404 Not Found: The requested resource could not be found.
• 429 Too Many Requests: Rate limit exceeded.
• 500 Internal Server Error: An unexpected error occurred on the server.

Rate Limiting

To ensure fair usage and stability, the API enforces rate limits. You are allowed a maximum of 100 requests per minute per API key.

If you exceed the rate limit, you will receive a 429 Too Many Requests response. The response headers will include:

• X-RateLimit-Limit: The maximum number of requests allowed in the current window.
• X-RateLimit-Remaining: The number of requests remaining in the current window.
• X-RateLimit-Reset: The time in UTC epoch seconds when the limit will reset.
