Frequently asked questions

Are my curl commands uploaded?

No — parsing happens in your browser. Curl commands routinely contain API keys and tokens in headers, which is exactly why they shouldn't be pasted into server-based converters.

Which curl options are understood?

-X/--request, -H/--header, -d/--data (and variants), --json, -u/--user (becomes a Basic auth header), plus common no-ops like -s and -L. Multipart -F isn't supported yet.

What code do I get?

Both a modern fetch() call and an axios() call, with JSON bodies converted to real objects instead of strings.
