From a one-off cURL to a documented endpoint

A cURL command is the lingua franca of HTTP — it is what you copy out of a terminal, paste into a bug report, or find at the top of every API tutorial. But a wall of curl -X POST … -H … -d … commands is not documentation: a reader cannot scan it, cannot tell which calls are authenticated, and cannot see the shape of a request body at a glance. This converter reads each command the way curl itself would — resolving the method, splitting the query string off the URL, collecting every header, capturing and pretty-printing the body, and recognising cookies, user-agent, referer and timeout flags — and renders all of it as a structured, browsable reference.

Authentication is treated as a first-class signal because it is the thing readers most need to know. A -u user:pass flag is recorded as Basic auth, and an Authorization: Bearer … header is detected and surfaced as a clear callout on the endpoint. The original command is always preserved verbatim alongside the parsed breakdown, so nothing is hidden — the docs show both the human-readable tables and the exact line you can copy and run.

Everything runs in your browser. The commands, the tokens, the cookies and the bodies never leave the page, which is precisely what lets you paste real production calls with live secrets to draft internal docs without anything being uploaded. The three export formats cover the common destinations: self-contained HTML you can host or hand to a client, Markdown for a repository README or wiki, and a JSON collection to drive other tooling.

Pair this with the rest of the API suite: convert a saved Postman collection with the Postman to Docs converter, compose a brand-new request and emit code in six targets with the API Request Builder, or turn a whole specification into a browsable reference with the OpenAPI / Swagger generator.

Our API 'docs' were a wiki page of raw cURL snippets. I pasted the whole batch in, hit generate, and got a proper HTML reference with a table of contents and per-endpoint headers and body tables. The Bearer-token detection automatically flagged the protected routes, which our old page never did.

I keep a .sh scratch file of example calls for each integration. Dragging it straight onto the upload zone and exporting Markdown means I can drop the result into the repo README in under a minute. The multi-line backslash commands parse perfectly, body JSON gets pretty-printed, nothing gets mangled.

The query-parameter and cookie extraction is genuinely useful for documenting the edge-case requests we test against. I'd love a way to edit the generated endpoint titles before export, but the JSON output lets me post-process it myself, so it's not a blocker.

Being fully in-browser is the selling point for us — I can paste real production cURL commands with live tokens to build internal docs and know nothing leaves my laptop. The self-contained HTML with the dark-mode toggle looks polished enough to hand straight to a client.
