AkousaAPI Tester
Test REST APIs directly in your browser. Send HTTP requests, inspect responses, generate code snippets, and save collections — no install required.
About API Tester
API Tester is a full-featured HTTP client that runs entirely in your browser. Send GET, POST, PUT, PATCH, DELETE, HEAD, and OPTIONS requests to any public API, inspect the response with a beautiful interactive JSON tree, and generate ready-to-use code snippets in cURL, JavaScript Fetch, Axios, Python requests, or Go. No account or installation required — your request history and saved collections are stored locally in your browser.
How to Use
Enter a URL in the address bar, choose an HTTP method, configure query parameters, headers, body, or authentication in the respective tabs, then click Send (or press Ctrl+Enter). The response status, timing, and size are displayed instantly. Use the JSON tree to explore nested response data, switch to Raw view for plain text, or check the Headers tab for response headers. Click Code to generate a code snippet in your preferred language, Import cURL to parse any curl command into the request builder, or Save to store the request in a named collection for later use.
