Craft Quantities: construction material calculators

Materials list for a whole job (takeoff)

run_takeoff

Read-onlyIdempotent

What materials does a whole job take: a concrete slab, a framed wall, a deck, a bathroom, a roof, a fence? Works the job's takeoff as its page does and returns every material quantity, what to order, waste allowances, both unit systems, labour hours (not a price), what is not counted, a citation and a page link. It does not size load-bearing members.

Input Schema

TableJSON Schema

Name	Required	Description	Default
`detail`	No	full (the default): the whole answer. summary: the result lines, the citation line and the page only — fewer tokens to read.	full
`market`	No	Optional. A market whose own opening choice some inputs take (a UK reader's code, an IEC motor), and whose currency symbol prints the caller's own money figures.
`system`	No	The unit system inputs left out open in, and the one the page link opens in. The answer comes in both.	metric
`takeoff`	Yes	A takeoff id, such as concrete-slab.
`leaveOut`	No	Rows the reader leaves out of the job: still worked and shown, not put in the project or counted in labour.
`selection`	No	Build-up choice id → option id, the takeoff's own (a stud size, an insulation, a cladding). Choices left out take the page's own for the system.
`allowances`	No	Row → an allowance the reader sets: a percentage (cutting waste, overlap), or the option an allowance follows (a lay pattern). Row names are the takeoff's steps (the calculator slug, or the step key where one runs twice).
`inputUnits`	No	Send "base" to pass bare numbers on dimensioned inputs in base units (m, m², L, kg …), as the published test vectors are written. Without it a length, area or volume must carry its unit.
`measurements`	No	Measurement id → value, each length, area or volume with its unit ("12 ft", {"value": 3.6, "unit": "m"}); counts as numbers. Ids are those of the takeoff; any left out opens at the page's own figure.
