API Tester
Test REST APIs, debug webhooks, import cURL commands, and share reproducible requests — all from your browser.
Ready to Test
Enter a URL and click Send to see the response here.
Built With Care
“When you test an API endpoint here, we route the request through our secure cloud proxy. This handles the common 'CORS' (Cross-Origin Resource Sharing) errors that usually block browser-based API tools, allowing you to test any public or local API effortlessly.”
REST API Tester & Debugger
Test your REST APIs directly from the browser with Axonix. Debug GET, POST, PUT, and DELETE requests, import cURL commands, set Bearer/Basic/API Key authentication, inspect headers, and share reproducible API calls with your team instantly.
- 1Select your HTTP method (GET, POST, PUT, DELETE, etc.).
- 2Enter the full URL of the API endpoint you want to test.
- 3Use the Auth tab to add Bearer tokens, Basic auth, or API keys.
- 4Add any necessary Headers or query Parameters.
- 5For POST/PUT requests, enter your JSON body payload in the Body tab.
- 6Click 'Send' to execute the request and view the status, time, and response data.
- Auth Presets: Bearer Token, Basic Auth, and API Key authentication with one-click setup.
- cURL Import: Paste any cURL command to auto-fill URL, method, headers, and body.
- Request History: Your recent API calls are saved locally for quick re-testing.
- CORS Handling: Our built-in proxy resolves cross-origin requests automatically.
- Shareable Links: Encode your entire request configuration into a single URL.
- Response Analysis: View status codes, response time, payload size, and searchable JSON body.
- Pretty/Raw Toggle: Switch between formatted JSON tree view and raw response text.
Real Ways People Use This
Debugging Webhooks
Simulate a webhook payload (POST request) to your local server or production endpoint to verify your listeners are working correctly.
Sharing Reproductions
Found a bug in your team's API? Configure the failing request and copy the 'Share' link to send a precise reproduction case to your backend developers.
Importing cURL Commands
Paste cURL commands from documentation, Stack Overflow, or browser DevTools to instantly populate the request without manually re-entering headers and body.
Quick Prototyping
Test public APIs (like weather, crypto, or social media) to understand their JSON structure before writing a single line of code.
- Requests run through a proxy path, so never send production secrets unless your team has explicitly approved that workflow.
- API behavior can differ across environments; validate endpoint base URLs and auth scopes before debugging logic.
- Share links may include headers, body, and auth data — remove secrets before sharing publicly.
- 1Set correct method, URL, headers, and auth before sending the request.
- 2Inspect status code, response body, and timing for expected behavior.
- 3If sharing with teammates, remove secrets and reproduce with a sanitized request link.
