API Request Tool
Send HTTP requests and inspect the response, with support for custom headers and request body
How to use
The API request tool is a web-based mini-Postman: pick a request method (GET/POST/PUT, etc.), enter a URL, add custom headers in the headers area one "Key: Value" per line, optionally fill in a request body for POST/PUT requests, and hit Send to view the status code, elapsed time, response headers, and response body. Response bodies over 200 KB are automatically truncated to keep the page responsive. Requests are sent through this site's backend server, so they bypass browser CORS restrictions — handy for quickly debugging third-party APIs or verifying that a callback endpoint is reachable. For security reasons, internal addresses (127.0.0.1, 10.x, 192.168.x, etc.) are refused, and the timeout is capped at 30 seconds. Do not include real production secrets in the request body.
