barcode

Runs in your own browser. Covers EAN/UPC, Code 128, GS1-128, ITF-14, Data Matrix and the rest. Separate from `qr-code`: a QR is one symbology, this is the rest of them, and the check digits differ per family.

Browser recipe

This tool runs in your own browser. The work order you receive carries this recipe with the placeholders filled in; the selectors below are a versioned contract, not implementation detail — they do not change without a version bump.

{
    "engine": "dom",
    "steps": [
        {
            "action": "select",
            "selector": "[data-tmb-api=\"type\"]",
            "value": "{{type}}"
        },
        {
            "action": "fill",
            "selector": "[data-tmb-api=\"value\"]",
            "value": "{{value}}"
        },
        {
            "action": "wait",
            "selector": "[data-tmb-api=\"download\"][data-tmb-format=\"{{format}}\"]",
            "timeout_s": 60
        },
        {
            "action": "click",
            "selector": "[data-tmb-api=\"download\"][data-tmb-format=\"{{format}}\"]"
        }
    ],
    "result": {
        "kind": "download",
        "settles": "automatically"
    }
}

What each action obliges you to do — recipes use nothing else:

`upload`	Put the input file into the file input matched by `selector` (it may be visually hidden: set it directly, e.g. Playwright setInputFiles). The file must match `accept`.
`click`	Click the element once it is visible AND enabled. A control that stays disabled means an earlier step did not take effect.
`fill`	Replace the value of a text input with `value`, firing input/change events as typing would.
`select`	Choose the option whose value is `value` in a <select>.
`wait`	Wait until the element is visible, up to `timeout_s` seconds (default 30).

Race every step against the work order's abort_when selector (html[data-tmb-run="failed"]). If it matches, the tool refused the job — for example a video that would not get any smaller. Stop, and GET the run: error.detail says why. Nothing is charged.

History

v2 — 2026-09-11 — The value step uses the documented `fill` action instead of the undocumented `set`. Same control, same effect; an agent implementing only documented actions now types the value.
v1 — 2026-08-02 — Initial release (browser lane).

This contract cannot change without a new version and a line above: a test compares the published schema, pricing and limits against a committed lockfile and fails the build otherwise. Subscribe to /v1/changelog to be told when something moves.
