よくある質問

Which curl flags are supported?

-X/--request, -H/--header, -d/--data (all variants), --json, -u basic auth, -b cookies, -A user agent, -e referer. Flags like -L, -k, -v are ignored (no direct fetch equivalent).

Does it handle multi-line commands with backslashes?

Yes - backslash-newline line continuations are respected, so you can paste directly from bash.

Does it upload my command?

No. Parsing runs entirely in your browser.

Why is my body wrapped in quotes for Python?

The Python target auto-detects application/json Content-Type and uses json= for a parsed dict. Non-JSON bodies pass through as data= strings.
