What it does

Also called: minify html · shrink an html file · remove whitespace from html.

Use it from your own code

The same endpoint this page calls — no daily cap, 2 credits a call either way.

POST /v1/markup/html-minify

curl -X POST "$DOATHING_API/v1/markup/html-minify" \
  -H "x-api-key: $DOATHING_KEY" \
  -H "content-type: application/json" \
  -d '{"text": "<p>  spaced  </p>  <!-- note -->"}'

Whitespace collapsed and comments dropped, without changing how the page renders.

Minify HTML by collapsing whitespace and removing comments, preserving pre and textarea content.

Input

Send either a text string or a file object. A file is decoded as UTF-8 and must be one of text/html, text/plain.

Response

The result carries your remaining balance alongside it, so you can track spend without a second call.

{
  "text": "<p>spaced",
  "bytes_in": 32,
  "bytes_out": 9,
  "saved_percent": 71.9,

}

Cost

2 credits per call, whether it is run from the site or from the API — the credential differs, the price does not. A new account starts with 20 credits.

A rejected request still costs a credit: the authorizer decrements before the tool validates. A call rejected for a missing or invalid key is free.

Parameters

Generated from the endpoint’s own validation, so this is exactly what it accepts. A body field goes at the top level; an option goes inside options.
