Calculate construction materials (how many, how much)
calculateRead-onlyIdempotent
How many bags of concrete, sheets of drywall or plasterboard, tiles, bricks, studs, litres or gallons of paint, tonnes of gravel, cubic yards or m³ does a job take, and how much? Runs the site's cited calculator as its page does and returns the quantity in metric and US customary, the inputs used, sources, a citation and a page link. Lengths carry units ("12 ft"). No prices.
Input Schema
TableJSON Schema
| Name | Required | Description | Default |
|---|---|---|---|
| slug | Yes | A calculator slug, such as concrete-calculator. | |
| detail | No | full (the default): the whole answer. summary: the result lines, the citation line and the page only — fewer tokens to read. | full |
| inputs | No | Input id → value. A length, area, volume or other measured input takes "12 ft", "3.5 m", "8' 3 1/2\"" or {"value": 12, "unit": "ft"}; a count or percentage takes a number; a select takes one of its option values. Inputs left out take the value the calculator's page opens on. | |
| 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 |
| 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. |
