cURL Command Builder
Used by developers, writers, and creators worldwide.
A cURL command builder assembles a correct, copy-paste-ready curl invocation from the pieces you choose, so you can test an API endpoint from the terminal without remembering every flag. Pick the HTTP method, paste the URL, and decide whether to attach a bearer token, and it returns the full command with the right headers, an Accept header, a Content-Type and JSON body for write methods, and a backslash-continued multi-line layout that stays readable. Developers use it to reproduce a request, share a working example in a bug report, or smoke-test an endpoint before wiring up real code. It runs entirely in your browser and generates instantly. Swap in your real URL, token variable, and request body, then paste it straight into any shell. The structure means you never forget the Content-Type header on a POST again.

FAQ
does it include authentication
When you tick the bearer token option it adds an Authorization header using a $TOKEN shell variable, so you can export your token once and reuse the command without pasting the secret inline.
why a JSON body for POST and PUT
Write methods usually send a payload, so the builder adds a Content-Type header and a sample JSON body for POST, PUT, and PATCH. Replace the placeholder fields with your real request shape.
will it work in any shell
The command uses standard curl flags and POSIX line continuation, so it runs in bash, zsh, and most Unix shells. On Windows, use it in WSL, Git Bash, or adjust the quoting for PowerShell.
