Picture Framing API

healthy 4,231 Subscribers

Picture-framing maths as an API, computed locally and deterministically — the mat-cutting and moulding numbers a framer or artist measures a job by. The mat endpoint sizes the mat board around an artwork: the window opening is the art minus a small overlap on each edge (≈ 0.25 inch so the mat holds the print), and the outer mat is the window plus the border widths — give one border or per-side borders, with a heavier bottom for a balanced, bottom-weighted mat, so an 8×10 print with a 2-inch border has a 7.5×9.5 window and an 11.5×13.5 mat. The moulding endpoint computes the frame stick needed: length = inner perimeter + 8 × the moulding width, because each of the four 45-degree mitred corners adds one moulding width — an 11.5×13.5 frame in 1.5-inch moulding needs 62.5 inches, plus any waste allowance. Everything is computed locally and deterministically, so it is instant and private. Ideal for picture-framing, custom-framing, art-gallery and DIY app developers, mat-cutter and moulding-estimating tools, and framing education. Pure local computation — no key, no third-party service, instant. Imperial inches in; lengths in inches and feet. Live, nothing stored. 2 compute endpoints. A planning aid — measure twice, cut once.

Lumber Calculator API

Lumber and framing material-estimation maths as an API, computed locally and deterministically. The boardfeet endpoint computes board feet — the standard volume unit for sawn timber, (thickness_in × width_in × length_ft) ÷ 12 — for a quantity of boards, with the total board feet and linear feet. The studs endpoint frames a wall: the number of vertical studs, ceil(wall length ÷ spacing) + 1 (16-inch ≈ 0.4064 m or 24-inch ≈ 0.6096 m centres), with two extra studs per opening, plus the plate boards for the top and bottom plates. The cost endpoint totals the lumber either by board foot (board feet × price per board foot) or by piece (pieces × price per piece). Everything is computed locally and deterministically, so it is instant and private. Ideal for construction, carpentry and DIY app developers, framing and material take-off tools, and lumberyard and builder calculators. Pure local computation — no key, no third-party service, instant. Live, nothing stored. 3 endpoints. This is lumber and framing estimation; for drywall sheets use a drywall API and for concrete use a concrete API.

Balloon Decor API

Party-balloon maths as an API, computed locally and deterministically — the helium-lift and balloon-count numbers a party planner or balloon artist decorates by. The helium endpoint gives a balloon’s lift from its inflated diameter: net lift is the inflated volume times the difference between air and helium density, about 1.046 grams per litre, so a fully inflated 11-inch latex balloon (around 11.4 litres) lifts roughly 12 grams gross and about 9 after its own weight, while a 36-inch giant lifts hundreds of grams. The float endpoint flips it around — how many balloons to float a payload = the weight divided by the net lift per balloon, rounded up, so a 50-gram card floats on six 11-inch balloons. The garland endpoint sizes an organic balloon garland or arch from its length: about 12 balloons per foot in a mix of sizes — roughly 40 % 5-inch, 45 % 11-inch and 15 % 16-inch for that full, textured look — so a 10-foot garland takes about 120 balloons, denser if you want it lush. Everything is computed locally and deterministically, so it is instant and private. Ideal for party-planning, event-decor, balloon-artist and celebration app developers, decor-estimator and shopping-list tools, and event software. Pure local computation — no key, no third-party service, instant. Inches and grams. Live, nothing stored. 3 compute endpoints.

Grain Bin API

Grain-bin storage maths as an API, computed locally and deterministically — the bushel and weight numbers a farmer or elevator sizes storage by. The bushels endpoint measures a round bin: floor area × grain depth gives the cubic feet, and a cubic foot holds about 0.8036 bushels, so an 18-foot bin filled 20 feet level holds roughly 4,090 bushels — and grain heaped to a peak adds a cone of (1/3) × floor area × peak height, so a 4-foot peak adds about 270 more. The weight endpoint converts bushels to weight by the crop’s standard test weight — corn and sorghum at 56 pounds a bushel, wheat and soybeans 60, oats 32, barley 48 — so those 4,090 bushels of corn weigh 229,040 pounds, about 114.5 US tons or 104 tonnes; pass a measured test weight for light or heavy grain. Everything is computed locally and deterministically, so it is instant and private. Ideal for agriculture, grain-elevator, farm-management and ag-tech app developers, storage-capacity and inventory tools, and harvest software. Pure local computation — no key, no third-party service, instant. US units (feet, bushels, pounds). Live, nothing stored. 2 compute endpoints.
