Waiting for server response.
What is an API Tester?
An API Tester is a developer tool that allows you to send HTTP requests to any endpoint and inspect the full response. It works like a simplified version of Postman, running entirely in your browser with server-side curl execution for reliable cross-origin requests.
Supported HTTP Methods
- GET: Retrieve data from an endpoint (default method for reading resources).
- POST: Send data to create a new resource.
- PUT: Update an existing resource completely.
- PATCH: Partially update an existing resource.
- DELETE: Remove a resource.
Response Analysis
After each request, you can inspect the full response including status code, response time, response size, response headers, and the formatted body. JSON responses are automatically pretty-printed for readability.
Frequently Asked Questions
Is my API data secure?
Yes. Requests are made server-side using cURL and responses are displayed in your browser. No data is stored on our servers.
Can I test authenticated APIs?
Yes. Add authorization headers (e.g., Bearer token, API key) in the Headers tab before sending your request.
