API Data Fetcher
Fetch, test, and analyze data from any API endpoint instantly.
Fetching API data... please wait.
Test Any REST API From Your Browser
Enter an API endpoint, pick the HTTP method, add custom headers and a request body, then fire the request — the formatted JSON response, status code, and timing appear instantly.
Perfect for debugging endpoints during development: inspect exactly what the server returned, how long it took, and which headers came back with it.
All HTTP methods
Send GET, POST, PUT, PATCH, and DELETE requests with custom headers and body payloads, just like a desktop API client.
Built-in CORS proxy
Test APIs that have not enabled CORS headers — requests are relayed through our server-side proxy so the browser never blocks them.
How it works
Your request is relayed through our server (fetch.php), which performs the actual HTTP call and returns the response. Because traffic passes through our server, use test credentials — never production secrets.
How to use
- Enter the API endpoint URL.
- Choose the HTTP method and add any headers or body data.
- Click Send Request.
- Read the formatted response, status code, and timing.
Frequently Asked Questions
How does the CORS proxy work?
Instead of calling the API directly from your browser (which CORS rules may block), the tool sends your request to our server, which makes the HTTP call and returns the result.
Which HTTP methods are supported?
GET, POST, PUT, PATCH, and DELETE — with custom headers and request bodies for the methods that accept them.
Can I test APIs that need authentication?
Yes. Add Authorization or custom headers to the request. For safety, use test or sandbox credentials rather than production keys.
Is my request data kept private?
Requests are relayed through our server to perform the call — avoid sending production secrets or sensitive personal data through the tool.
Is the API tester free?
Yes, free with no signup.
