cURL Command Generator
Documenting an API endpoint is much clearer with a runnable curl example than with a prose description. This generator produces complete, correctly-formatted curl commands for GET, POST, PUT, DELETE, and PATCH requests — with Accept and Authorization headers, and a JSON body with Content-Type header for write methods — that you can paste into a terminal, a README, or a Postman import. The HTTP method dropdown selects the method, or random draws from all five. Each generated command uses one of four realistic API hostnames and one of five path patterns including versioned paths like /v1/users or /v2/search?q=test. POST, PUT, and PATCH commands include -d with a minimal JSON body and the matching Content-Type: application/json header. The command uses backslash line continuations so it is readable across multiple lines but can be pasted directly into a shell. The generated output is well-formed and follows curl conventions, but two placeholders need replacing before running: the host and path reflect example domains, and the Authorization header contains the literal string <token> rather than a real credential. Replace both with your actual values and the command runs as written.

Detailed instructions
- Choose an HTTP method, or leave it on random.
- Click Generate to produce a complete curl command.
- Replace the placeholder host, path, and token with real values.
- Copy it into your terminal, documentation, or bug report.
Use Cases
- •Documenting an API endpoint with a copy-ready example
- •Reproducing a request to test or debug it
- •Learning curl flags and HTTP method syntax
- •Including a runnable request in a bug report
- •Quick examples for tutorials and READMEs
Tips
- →Wrap the URL in quotes so query strings with & do not break in the shell.
- →Use single quotes around a JSON body so inner double quotes survive.
- →Add -i or -v to inspect response headers when debugging.
- →Replace the bearer token placeholder before running against a real API.
FAQ
what is curl used for
curl is a command-line tool for making HTTP requests, widely used to call and test APIs, download files, and reproduce requests. A well-formed curl command is the most portable way to document or share an exact request, since it runs the same everywhere curl is installed.
how do I send a json body with curl
Use the -d flag with a JSON string and set the Content-Type header to application/json, as the generated POST, PUT, and PATCH commands show. The body must be valid JSON, and on the command line it is usually wrapped in single quotes so inner double quotes are preserved.
are these commands runnable as-is
They are well-formed and runnable once you replace the example hostname/path and the <token> placeholder in the Authorization header with real values. The flag structure, header names, and line continuations all follow curl conventions, so the command works as soon as it points at a real endpoint with valid credentials.
do DELETE and GET commands include a request body
No. Only POST, PUT, and PATCH commands include a -d body flag and a Content-Type header. GET and DELETE commands include only the Accept and Authorization headers, which matches standard HTTP semantics where GET and DELETE do not carry a request body.
