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.

Backyard-chicken housing maths as an API, computed locally and deterministically — the coop, run and fixture numbers a flock keeper builds to. The space endpoint sizes the housing from the flock and the breed: about 4 ft² of coop floor per standard hen (2 for bantams, 5 for heavy breeds) plus roughly 10 ft² of run each, so ten standard hens want a 40 ft² coop and a 100 ft² run — and given a coop width it returns the length, or zero run for birds that free-range and only roost inside. The fixtures endpoint covers the inside: one nest box per three to four hens (they share and queue, so ten hens need three), 8–12 inches of roost bar per bird (ten birds ≈ 8.3 feet), about 4 inches of linear feeder space each, and a waterer per eight or so birds. Crowding is the root of pecking, disease and mess, so every figure rounds up and more space is always better; roosts should sit higher than the nest boxes so the birds don’t sleep — and soil — in them. Everything is computed locally and deterministically, so it is instant and private. Ideal for homesteading, backyard-poultry, farm and smallholding app developers, coop-planner and flock-management tools, and self-sufficiency software. Pure local computation — no key, no third-party service, instant. US units, rules of thumb. Live, nothing stored. 2 compute endpoints. For feed quantities use a different API.
