  • Every result with timing

Who it is for

Backend developers and QA

  • Smoke-test an API after deploy
  • Check security headers and leaked fields
  • Test error handling without writing scripts

Why use this instead of Postman, Insomnia?

  • No collections to build — list endpoints in plain text
  • Negative cases tried automatically
  • Credential used only during the run, never saved

How it works

  1. Validate the host
  2. Call each endpoint
  3. Run negative cases
  4. Report errors and latency

What we read

The endpoints you list. Without a verified website, up to 20 requests.

Limits: Only GET and HEAD requests, capped by your limit. Use a test environment.
