Which curl flags are supported?

-X / --request (method), -H / --header (headers), -d / --data / --data-raw / --data-binary (body), -u / --user (Basic auth → Authorization header), -b / --cookie (Cookie header). Multi-line backslash continuations are handled.

Does the generated code include error handling?

Basic structure is included (try/catch in JS, try/except in Python, etc.) but production-grade error handling is intentionally minimal so the snippet stays readable. Add logging and retries to suit your project.

Is my curl command sent to a server?

No. All parsing and code generation runs entirely in JavaScript in your browser. Nothing is transmitted.

What if I have a Bearer token in the -H flag?

The -H flag value is passed through as-is to the generated code. So -H "Authorization: Bearer TOKEN" produces the exact same header in all generated snippets.

OutputMulti-language POST snippet with headers and body

Common errorsAnd how to fix them

Could not extract a URL from the curl command

Cause: The curl command is missing the URL argument or uses an unsupported alias.

Fix: Make sure the URL appears as a plain argument (e.g. curl https://example.com). Wrap it in quotes if it contains special characters.

Generated code shows unknown method

Cause: No -X / --request flag was found and the input did not contain a body flag (-d, --data), so the method could not be inferred.

Fix: Add -X GET or -X POST explicitly to the curl command.
