How the parser reads a cURL command — illustrated

A shell tokenizer first splits the command, honoring single quotes (no escapes inside), double quotes (\\" \\$ escapes), and backslash continuations. Then a flag pass maps each option: -H becomes a header pair, repeated -d flags join with & exactly as cURL sends them, -F flags signal multipart FormData, -u becomes HTTP Basic auth, and the method defaults to POST when a body exists, GET otherwise. Output is copy-paste runnable — but review it: secrets in the command end up in the code.

Quote handling follows real shell semantics: single quotes are literal, double quotes allow escapes, backslash continues lines.

Documenting an API call — Kai's integration notes

Kai copies a working cURL from a Stripe-style dashboard and needs it inside his Next.js route handler.

  1. Paste the command:The multi-line command (backslash continuations) parses to POST, two headers, and a JSON body — nothing to configure
  2. Pick fetch:The emitted code is a drop-in await fetch(url, { method, headers, body }) for his route handler
  3. Check the secrets:The Authorization bearer token from the command appears in the code — expected, since he pasted it locally; the privacy badge reminds him nothing was uploaded
  4. Swap targets:For the Python docs he re-exports the same parse as requests code — one parse, three targets

Why Convert cURL at All

API documentation speaks cURL; your application speaks Fetch, Axios, or Python requests. Retyping a complex command - headers, auth, multipart bodies - is where transcription bugs live. Pasting the command and getting correct, idiomatic code in your actual HTTP client removes the entire class of copy mistakes.

Parsing Like a Shell, Running Like a Browser

The tokenizer mirrors Unix shell rules: single-quoted strings are literal, double-quoted strings honor backslash escapes, and trailing backslashes join continued lines. The parsed request - method, URL, headers, body, auth - previews live before generation, and the whole pipeline runs in your browser so credentialed commands never leave the page.

Frequently Asked Questions

Which cURL flags are supported?

The parser reads -X (method), -H (repeated headers), -d (multiple bodies are joined with an ampersand), -F (multipart with @file detection), -u (basic auth), --url, -L (follow redirects), -k (insecure), -I (HEAD), -A (user agent), -e (referer), and -b (cookies). Unsupported flags are reported instead of silently dropped.

How are quotes and escapes handled?

Commands are tokenized with a shlex-style parser: single quotes protect everything inside, double quotes allow backslash escapes, and backslash line continuations join multi-line commands. This mirrors how a Unix shell would parse the same command.

Is my API token sent anywhere?

No. Parsing and code generation run entirely in your browser - a cURL command containing an Authorization header never leaves the page. This is exactly why the tool exists: pasting credentialed cURL into random websites is a real leak vector.
