API Tester
FreeTest REST API endpoints with GET, POST, PUT, DELETE
About API Tester
When you're building or debugging an API, you need to fire off requests fast and see exactly what comes back. The API Tester lets you hit any REST endpoint with GET, POST, PUT, or DELETE and read the raw response, status code, and timing without opening a heavy desktop client or writing a throwaway curl command. It's built for the quick checks that happen dozens of times a day during development.
Pick a method, paste your URL, add a body if you need one, and send. The request runs straight from your browser and the response appears instantly, formatted and ready to read. It's free, requires no signup, and nothing about your requests is stored, so you can test internal or staging endpoints without worrying about a third party logging them.
Common uses
- Confirm a new POST endpoint accepts your payload and returns the expected 201 before wiring it into your frontend.
- Quickly reproduce a bug a teammate reported by replaying the exact GET request against staging.
- Verify that a DELETE route actually removes a resource and returns the right status code.
- Check how an endpoint responds to a malformed PUT body while testing your validation logic.
- Smoke-test a third-party API's basic behaviour before committing to its integration.

FAQ
Which HTTP methods can I use?
GET, POST, PUT, and DELETE are supported, covering the operations you need for most CRUD-style API testing.
Can I send a request body?
Yes. For POST and PUT requests you can include a body, which is useful for testing endpoints that expect JSON or form data.
Will CORS affect my requests?
Because requests run from your browser, endpoints that don't allow cross-origin calls may block them. APIs with permissive CORS or proper headers work fine.
Are my requests saved anywhere?
No. The tool runs in your browser and doesn't store your URLs, bodies, or responses.
Can I use API Tester on mobile?
Yes — ToolHub is fully responsive and works on iPhone, Android, tablets and all modern browsers. No app install needed.
