Welcome to OsintCat API

OsintCat provides a powerful REST API for OSINT (Open Source Intelligence) lookups, breach data searches, and public record queries. Our API enables developers to integrate comprehensive data lookup capabilities into their applications.

​
Base URL

All API requests should be made to: 
https://www.osintcat.net/api

​
Authentication

All API endpoints require authentication using an API key. Include your API key as a query parameter named id in every request.
Keep your API key secure and never expose it in client-side code or public repositories.

​
Example Request

curl "https://www.osintcat.net/api/user?id=YOUR_API_KEY"

​
Rate Limits

Our API has a soft rate limit of 3 requests per second. If you exceed this limit, you will receive a 30-minute timeout.
Rate Limit Warning: Exceeding 3 requests per second will result in a 30-minute timeout. Please implement proper rate limiting in your application.

  • 400 - Bad Request (missing or invalid parameters)
