Drywall (plasterboard) material-estimation maths as an API, computed locally and deterministically. The sheets endpoint computes how many boards a wall or ceiling needs — the area (given directly, or as perimeter × height, or length × width) divided by the sheet area, with a waste allowance — and the number of screws (about 32 per standard sheet). The compound endpoint estimates the joint compound in kilograms and the joint tape in metres for taping and finishing the boarded area, with adjustable per-square-metre factors for your product and number of coats. The cost endpoint totals the project from the sheets and their price plus the compound and tape. The standard 2.4 × 1.2 m board is assumed unless you override it. Everything is computed locally and deterministically, so it is instant and private. Ideal for construction, renovation and trade app developers, drywall and plastering estimators, and builder and retailer tools. Pure local computation — no key, no third-party service, instant. Live, nothing stored. 3 endpoints. This is drywall material estimation; for insulation R-values use a U-value API and for wall paint use a paint API.

Wallpaper-estimating maths as an API, computed locally and deterministically. The rolls endpoint uses the proper drop method: it works out how many full-height drops come from each roll, floor(roll length ÷ (wall height + pattern repeat)), how many drops the room perimeter needs, ceil(perimeter ÷ roll width), and from those the rolls required — so a larger pattern repeat correctly increases the count. The simple endpoint gives a quick area-based estimate, rolls = ceil(wall area·(1+waste) ÷ roll coverage), handy for plain papers. The cost endpoint totals the project from the rolls and price per roll plus the adhesive, with one tub of paste hanging about five rolls. The standard roll of 10.05 m × 0.53 m is assumed unless you override it. Everything is computed locally and deterministically, so it is instant and private. Ideal for home-decor, renovation and trade app developers, DIY and room-planning tools, and decorator and retailer calculators. Pure local computation — no key, no third-party service, instant. Live, nothing stored. 3 endpoints. This is wallpaper estimation; for wall paint use a paint API and for floor tiles use a flooring API.
