API 请求构建器
可视化构建和发送 HTTP 请求，支持请求头、查询参数、请求体及自动生成 cURL/fetch 代码
API Request Builder — Visual HTTP Client
Build and send HTTP requests visually — like a lightweight Postman in your browser. Set method, URL, headers, query params, and body, then copy the auto-generated cURL or fetch() snippet.
FAQ
What is an API request builder?
It's a visual tool for constructing HTTP requests without writing code. You fill in the method (GET, POST, etc.), URL, headers, and body — the tool assembles and sends the request, then displays the response.
Can I test REST APIs with this tool?
Yes — enter your API endpoint, add Authorization headers or API keys, set a JSON body for POST requests, and send. The response body, status code, and headers are displayed immediately.
How is this different from Postman?
Postman is a full desktop app with workspaces, history, and team features. This tool runs entirely in your browser with no installation, no account, and no data stored — perfect for quick one-off requests.
