Caulk Coverage API

healthy 4,064 Subscribers

Caulk and sealant coverage maths as an API, computed locally and deterministically — the linear-feet-per-tube and how-many-tubes numbers a builder, glazier or DIYer buys sealant by. A bead of caulk is essentially a thin cylinder, so the coverage endpoint works out the feet a cartridge lays from the bead width: volume per foot ≈ (π/4 × width²) × 12 inches, and a standard 10.1 fl oz cartridge (18.2 in³) lays about 30 feet of a quarter-inch bead, 13 feet of a fat three-eighths or 55 of a fine three-sixteenths — pass cartridge_oz for sausage packs or 28-oz tubes, and a tube count to total it. The tubes endpoint runs it backwards: cartridges needed = (joint length × a waste factor) ÷ feet per cartridge, rounded up, so a 100-foot run of quarter-inch bead with 10 % waste takes four tubes. Everything is computed locally and deterministically, so it is instant and private. Ideal for construction, glazing, weatherproofing and home-improvement app developers, material-estimator and shopping-list tools, and contractor software. Pure local computation — no key, no third-party service, instant. Inches and feet; estimates — tooling and waste vary. Live, nothing stored. 2 compute endpoints.

ADA Ramp API

ADA wheelchair-ramp maths as an API, computed locally and deterministically — the run, landing and slope numbers a builder or accessibility planner sizes a ramp by. The rule the ADA fixes is 1 inch of rise per 12 of run, a maximum 8.33 % slope, so the ramp endpoint turns a rise into the ramp: run = rise × 12 (or × 16 / × 20 for a gentler grade if you have the room), plus the level landings the code requires — a 5-foot landing top and bottom and another between runs whenever the rise exceeds 30 inches — and the total length end to end, so a 24-inch rise needs a 24-foot run and 34 feet overall, while a 36-inch rise breaks into two runs with an intermediate landing for 51 feet. The fit endpoint answers the real-world question: does a ramp for this rise fit the run you have? It returns the minimum run an ADA 1:12 ramp needs, whether your space is enough, and the slope you would actually get if you forced it in — flagging when that exceeds 8.33 % and you need a switchback or a lower rise. Everything is computed locally and deterministically, so it is instant and private. Ideal for construction, accessibility, home-modification and contractor app developers, ramp-estimator and code-check tools, and building software. Pure local computation — no key, no third-party service, instant. Confirm against current ADA and local code. Live, nothing stored. 2 compute endpoints.

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.

Masonry Estimating API

Masonry estimating maths as an API, computed locally and deterministically — the brick, block and mortar counts a bricklayer, builder or estimator works to. The brick endpoint computes how many bricks a wall needs from its area (or length × height in feet): bricks per square foot = 144 / ((brick length + joint) × (brick height + joint)), so a standard modular brick with a 3/8-inch mortar joint works out to the well-known 6.86 bricks per square foot — a 100 ft² wall is 686 bricks, plus a waste allowance and the mortar bags (about 7 per 1000 bricks). The block endpoint does the same for concrete masonry units: a standard 16×8-inch CMU with a 3/8-inch joint is 1.125 blocks per square foot, with roughly 2.5 mortar bags per 100 blocks. Both endpoints take custom unit face dimensions and joint thickness, add a configurable waste percentage and round up to whole units. Everything is computed locally and deterministically, so it is instant and private. Ideal for construction, masonry-contractor, building-supply and home-improvement app developers, takeoff and material-estimating tools, and trade calculators. Pure local computation — no key, no third-party service, instant. Imperial units (inches and square feet). Live, nothing stored. 2 compute endpoints. This is brick/block and mortar estimating; for poured-concrete volume use a concrete API and for drywall use a drywall API.

Roof Pitch API

Roofing geometry as an API, computed locally and deterministically. The pitch endpoint converts freely between the three ways trades describe a roof slope — the pitch as rise per 12 of run (the X:12 notation), the angle in degrees and the slope as a percentage — using angle = atan(pitch/12); a 6:12 roof is 26.57° and a 50 % slope, and it also returns the pitch multiplier √(1 + tan²) that scales a flat plan length to the true along-slope length. The rafter endpoint computes the common rafter length from the horizontal run and the pitch, rafter = √(run² + rise²) with rise = run·tan(angle), and adds the along-slope length of an optional horizontal overhang — a 12-unit run at 6:12 needs a 13.42-unit rafter. The area endpoint converts a flat building footprint into the actual sloped roof surface area, footprint / cos(angle), the figure you need to order shingles, membrane or underlay; a 100 m² footprint under a 6:12 roof is about 111.8 m². Lengths are unit-agnostic — use a consistent unit. Everything is computed locally and deterministically, so it is instant and private. Ideal for roofing, construction, contractor-estimating, home-improvement, solar-install and architecture app developers, take-off and material-ordering tools, and trade software. Pure local computation — no key, no third-party service, instant. Live, nothing stored. 3 endpoints. This is roofing-specific geometry; for a general grade or gradient use a slope API.
