Flooring & Tile API
Flooring and tiling material-estimation maths as an API, computed locally and deterministically. The tile endpoint computes how many tiles a floor needs — the floor area (given directly or as length × width) divided by the tile area, with a waste allowance for cuts and breakage (10 % by default) — and, given the tiles per box, how many boxes to buy. The packs endpoint sizes laminate, vinyl or carpet from the coverage printed on each pack: packs = ceil(area·(1+waste) / coverage per pack), with the total coverage supplied. The grout endpoint estimates the grout in kilograms for a tiled area from the tile size, the joint width and the tile thickness, ((A+B)/(A·B))·joint·thickness·density per square metre. Everything is computed locally and deterministically, so it is instant and private. Ideal for home-improvement, renovation and trade app developers, DIY and material-ordering tools, and builder and retailer calculators. Pure local computation — no key, no third-party service, instant. Live, nothing stored. 3 endpoints. This is floor-covering estimation; for wall paint use a paint API, for roofing use a roofing API and for concrete use a concrete API.

Construction Calculator API
Construction and material estimating as an API — the everyday "how much do I need to buy" maths for building and renovation jobs, computed locally and deterministically from standard geometry and trade rules of thumb. The paint endpoint works out the litres and number of cans for a surface, allowing for the number of coats and the paint's coverage and deducting doors and windows. The tile endpoint computes how many tiles (and full boxes) a floor or wall area needs from the tile dimensions and a wastage allowance. The concrete endpoint gives the concrete volume in cubic metres, cubic yards and litres — and the number of pre-mix bags — for a slab, footing, wall or round column, with an optional batch quantity. The bricks endpoint computes how many bricks a wall needs from the brick size and mortar joint (default 215×65 mm brick with a 10 mm joint ≈ 60 bricks per square metre). Everything is computed locally and deterministically, so it is instant and private. Ideal for builders' merchants and trade apps, DIY and home-improvement tools, quoting and estimating software, and project planners. Pure local computation — no key, no third-party service, instant. Live, nothing stored. Estimates are guidance — allow for site conditions and follow the manufacturer's stated figures. 4 endpoints. This is materials estimating; for plain unit conversion use a unit-conversion API and for tyre or drivetrain maths use a tyre API.

Sauna Heater API
Sauna-heater sizing maths as an API, computed locally and deterministically — the heater-power, stone-mass and electrical numbers a sauna builder, installer or wellness retailer sizes a cabin with. The heater-size endpoint gives the power: about 1 kW per 1.3 m³ of well-insulated cabin (room volume ÷ 1.3), with cold surfaces the heater must also warm — a glass door or wall, bare stone, tile or uninsulated timber — adding roughly 1.2 m³ of equivalent volume per square metre, so a 10 m³ room with a 2 m² glass door wants about a 10 kW heater, rounded up to the next standard size. The stones endpoint gives the recommended sauna-stone mass, roughly 10–20 kg per kW (more stones for a softer, steamier löyly, fewer for a faster warm-up), with a note to use proper peridotite/olivine stones stacked loosely. The electrical endpoint gives the current the resistive heater draws — power ÷ voltage for single-phase or ÷ (√3 × voltage) for three-phase, since most heaters above ~4 kW are wired three-phase to keep the per-leg current and cable size down — to size the breaker and the dedicated RCD-protected circuit. Everything is computed locally and deterministically, so it is instant and private. Ideal for sauna and wellness retailers, home-improvement and DIY tools, and HVAC/electrical estimating apps. Pure local computation — no key, no third-party service, instant. Estimates — follow the heater maker's chart and local wiring code. 3 compute endpoints. For steam-boiler maths use a boiler API; for room heat loss a U-value API.

Deck Builder API
Deck-building maths as an API, computed locally and deterministically — the board, joist and fastener counts a homeowner or contractor needs to material out a rectangular deck. The boards endpoint turns the deck size into a real shopping list: rows = deck width ÷ (board width + gap), rounded up, so a 16 ft × 12 ft deck with a 5.5-inch board face (a 5/4×6) and a 1/8-inch gap needs 26 rows; boards run the length, each row takes one 16 ft board, and a 10 % waste allowance brings it to 29 boards plus the linear footage and the deck area. The joists endpoint frames it: joists are spaced along the length, so count = ⌊length ÷ spacing⌋ + 1 — thirteen joists at 16-inch on-center (seventeen at 12-inch for stronger or diagonal decking), each spanning the width, plus two rim joists and a ledger as total framing linear feet. The fasteners endpoint counts the screws: every decking row crosses every joist once and is fastened with two face screws there, so a 16×12 deck takes 26 × 13 × 2 = 676 screws, about 744 with waste — or one hidden clip per intersection. Everything is computed locally and deterministically, so it is instant and private. Ideal for construction, contractor, home-improvement, building-materials and renovation app developers, deck-estimator and takeoff tools, and lumber-yard calculators. Pure local computation — no key, no third-party service, instant. US units (feet/inches). Live, nothing stored. 3 compute endpoints. Rectangular decks; for indoor floor area use a flooring API.

Handrail & Baluster API
Railing and baluster layout maths as an API, computed locally and deterministically — the baluster-count, spacing and post numbers a deck builder, fabricator or balustrade designer sets a guardrail out with. The baluster-count endpoint gives the smallest number of balusters that keeps every gap within the safety limit: between two posts n balusters leave n+1 gaps, so the count = ceil((rail length − max gap) ÷ (baluster width + max gap)). The usual guardrail limit is a 100 mm (4-inch) sphere — a child-safety rule — so a 2000 mm rail with 40 mm balusters needs 14 of them at even 96 mm gaps; round up, because one fewer opens the gaps past the limit. The layout endpoint sets out a known count evenly: the gap = (rail length − total baluster width) ÷ (count + 1), the centre-to-centre pitch = baluster width + gap, and the first baluster's centre sits one gap plus half a baluster from the post face, so you mark the first centre and step off the pitch with the last gap landing equal to the first. The post-count endpoint sizes the frame: a run needs one more post than spans, spans = ceil(run ÷ max post spacing), posts = spans + 1, even spacing = run ÷ spans — a 6 m run at a 1.8 m max takes 4 spans and 5 posts at a tidy 1.5 m. Everything is computed locally and deterministically, so it is instant and private. Ideal for deck and balustrade design tools, fabrication and estimating apps, and building calculators. Pure local computation — no key, no third-party service, instant. Uses the common 100 mm infill rule — confirm your local code. 3 compute endpoints. For stair rise and run use a stair API; for fence pickets a fence API.
