Frequently Asked Questions
No — clicking Process shows a fixed message recommending real tools; it never makes an HTTP request or contacts any API.
A genuine API testing tool needs to make arbitrary cross-origin HTTP requests with custom headers/methods/bodies and handle auth flows — a much bigger undertaking than this lightweight browser tool, and often blocked by browser CORS restrictions when called from a third-party site like this one.
Postman or Insomnia — both are free, widely used, and built specifically for sending and inspecting real API requests, including OAuth, custom headers, and saved collections.
No — since no real request is made, nothing you type is transmitted.
