Paste a cURL command to automatically parse it into HTTP request parameters:
This tool helps developers quickly convert HTTP request parameters into standard cURL commands, eliminating the need to memorize complex syntax. Whether you are debugging API endpoints, sharing request examples, or writing automation scripts, this tool significantly boosts your workflow.
Basic Workflow: Start by selecting an HTTP method (GET, POST, PUT, etc.) from the dropdown menu, then enter the target URL in the input field. If you need to pass query parameters, click "Add Parameter" and enter the key and value-the tool will automatically append them to the URL. For POST/PUT requests that require a body, select a body type (JSON/Form/Raw) and fill in the content.
Header Configuration: Click "Add Header" to add any number of HTTP headers. Common headers like Content-Type: application/json, Authorization: Bearer token, or User-Agent can be configured easily. This is essential for APIs that require authentication or specific content types.
Reverse Parse Feature: If you have a cURL command on hand and want to inspect its parameters, use the reverse parse feature. Paste the cURL command into the parse area, click "Parse cURL", and the tool will extract the method, URL, headers, and body, populating the form above for easy review and editing.
Security Note: This tool runs entirely in your browser. All data is processed locally and never uploaded to any server. You can safely paste cURL commands containing API keys and other sensitive information for parsing-your data will not leak.
API Debugging: When developing RESTful APIs, you often need to convert requests captured from browser DevTools into cURL commands for server-side reproduction. This tool performs this conversion instantly, avoiding manual concatenation errors.
Team Collaboration: When describing an HTTP request to a colleague, sharing a cURL command is more precise than describing steps. Team members can reproduce the request in any environment with cURL installed, without needing heavy tools like Postman.
Automation Scripting: When writing shell scripts or CI/CD pipelines, embedding HTTP requests is common. cURL commands integrate directly into scripts, making them the standard choice for automation tasks. This tool generates correct command syntax, helping you avoid common quoting and escaping pitfalls.
Learning and Teaching: For newcomers learning HTTP protocols and API development, understanding cURL command composition through a visual interface is more intuitive than reading documentation alone. The reverse parse feature also helps analyze captured network requests, deepening understanding of HTTP mechanics.
Common cURL Options Quick Reference: -X specifies the HTTP method, -H adds headers, -d sends body data, -i shows response headers, -v shows verbose debug info, -L follows redirects, -o saves response to file, -u sets Basic Auth username and password, -k ignores SSL certificate verification, --cookie sends cookies, -F uploads files.
HTTP Method Meanings: GET retrieves resources, POST creates resources, PUT performs full updates, PATCH performs partial updates, DELETE removes resources, HEAD retrieves response headers without a body, and OPTIONS discovers supported HTTP methods. In RESTful API design, these methods map to CRUD operations.
Common Content-Type Values: application/json for JSON data, application/x-www-form-urlencoded for form data, multipart/form-data for file uploads, text/plain for plain text, application/xml for XML data, and application/octet-stream for binary streams. Setting the correct Content-Type is critical for servers to parse requests properly.
cURL (Client URL) is a command-line tool for transferring data between a client and a server. It supports HTTP, HTTPS, FTP, and many other protocols, making it an essential tool for developers and DevOps engineers to debug APIs, download files, and test endpoints. With cURL commands, you can reproduce HTTP requests from browsers or Postman directly in the terminal.
The tool supports GET, POST, PUT, DELETE, PATCH, HEAD, and OPTIONS. Each method can be configured with URL, headers, and body through the visual interface, and the corresponding cURL command is generated with a single click.
No. This tool processes everything client-side in your browser. No data is sent to any server. You can use it offline, and sensitive information such as API keys will never leave your device.
Yes. You can paste a complete cURL command, and the tool will automatically parse the HTTP method, URL, headers, and body, populating the corresponding form fields for easy review and editing.
Yes. The generated cURL commands follow standard syntax and can be run directly in Linux, macOS, or Windows terminals. If your command contains sensitive information such as API keys, please ensure you use it in a secure environment.
The current version focuses on text-based HTTP requests and does not yet support file upload cURL generation. You can manually add -F "file=@path/to/file" to the generated command to enable file uploads.
Windows 10 version 1803 and later includes cURL by default. On earlier versions, you can use cURL through Git Bash, WSL, or Cygwin. Note that double-quote escaping rules in PowerShell differ slightly from Linux.
This tool automatically handles escaping for most special characters. For values containing quotes, backslashes, or other special characters, the tool applies appropriate escaping to ensure the generated command is correct. If a generated command fails in your terminal, check character encoding and quote matching.
