Screw Auger API

Screw-conveyor and grain-auger maths as an API, computed locally and deterministically — the capacity, speed and throughput numbers a farmer, millwright or material-handling engineer sizes an auger with. The capacity endpoint gives the volumetric throughput from the screw geometry: the annular flight volume per turn ((π/4)(diameter² − shaft²) × pitch) × rpm × 60 × the trough loading, so a 9-inch full-pitch screw on a 2.5-inch shaft at 40 rpm and 45 % loading moves about 330 cubic feet — 265 bushels — an hour. The speed endpoint inverts it, the rpm needed for a target capacity, so you don't overspeed a small auger and grind the grain. The bushels endpoint converts a volumetric rate to bushels and tons per hour (1 bushel = 1.2445 ft³, tons = bushels × test weight ÷ 2000), so 330 ft³/hr of 56-lb corn is 265 bushels or 7.4 tons an hour — the number you match to the dryer or the truck. Everything is computed locally and deterministically, so it is instant and private. Ideal for grain-handling and ag-equipment apps, material-handling and conveyor-design tools, farm-build calculators, and engineering aids. Pure local computation — no key, no third-party service, instant. Live, nothing stored. 3 compute endpoints. Estimates — incline and material change real throughput. For belt conveyors use a conveyor API.

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.

Aquaculture API
Fish-farming (aquaculture) maths as an API, computed locally and deterministically — the stocking, feed and oxygen numbers a fish farmer or RAS designer runs a system on. The stocking endpoint turns a tank or pond volume and a target biomass density into a fish count: biomass = density × volume, count = biomass ÷ average fish weight — a 10 m³ tank at 30 kg/m³ holds 300 kg, about 1,200 fish at 250 g each, and you stock to the harvest weight, not the fingerling weight, so the tank does not overload as they grow. The feed endpoint gives the daily ration as a percentage of body weight, and the feed to reach a target weight gain through the feed conversion ratio — 300 kg fed at 2 % is 6 kg a day, and growing 100 kg of fish at an FCR of 1.2 takes 120 kg of feed. The oxygen endpoint gives the dissolved-oxygen demand of a stock — biomass × the per-kg consumption rate — so 300 kg at 300 mg O₂/kg/hr needs 90 g of oxygen an hour, the number your aeration must beat. Everything is computed locally and deterministically, so it is instant and private. Ideal for aquaculture and RAS-design apps, fish-farm management tools, hatchery and feed calculators, and ag-tech sites. Pure local computation — no key, no third-party service, instant. Live, nothing stored. 3 compute endpoints. Commercial-planning estimates — species and system vary. For a home aquarium use an aquarium API.

Rotational Grazing API
Rotational-grazing maths as an API, computed locally and deterministically — the animal-unit, grazing-day and acreage numbers a rancher or homesteader moves a herd by. It all hangs on the animal unit: a 1000-pound cow eating about 26 pounds of dry matter a day. The animalunits endpoint converts a mixed herd to that common basis — a cow is 1.0 AU, a cow-calf pair 1.3, a horse 1.25, a sheep 0.2, a goat 0.17 — so ten cows and fifty sheep are 20 AU demanding 520 pounds of forage a day; pass a weight instead and it scales by weight ÷ 1000. The days endpoint works out how long a paddock lasts: grazing days = (acres × forage per acre × utilization) ÷ (animal units × 26), where the classic “take half, leave half” puts utilization near 50 %, so five acres yielding 3,000 lb at 50 % feeds 10 AU for about 29 days. The acres endpoint sizes the paddock the other way — acres = (AU × 26 × days) ÷ (forage × utilization) — so 20 AU for a 30-day move needs about 10.4 acres. Everything is computed locally and deterministically, so it is instant and private. Ideal for ranching, regenerative-agriculture, homesteading and farm-management app developers, paddock-planner and stocking-rate tools, and grazing-chart software. Pure local computation — no key, no third-party service, instant. US units; forage yield varies with season — measure it. Live, nothing stored. 3 compute endpoints.

Plant Spacing API
Plant-spacing and planting-density maths as an API, computed locally and deterministically. The grid endpoint works out how many plants fill an area in a square (rectangular) layout: from a spacing (one value, or separate row and in-row spacings) and either an area or a length and width, it returns the planting density per square metre, square foot, 1,000 ft², acre and hectare, an area-based plant estimate, and — when you give length and width — an exact edge-inclusive grid count with the number of rows and plants per row. The triangular endpoint does the same for an offset (hexagonal) layout, where rows sit spacing × √3/2 apart and fit about 15.47 % more plants than a square grid at the same spacing, and it reports the gain. The density endpoint converts a spacing into a planting density in several units, or works in reverse: give a number of plants and an area and it recommends the spacing that fills it. Lengths accept millimetres, centimetres, metres, inches or feet; area accepts m², ft², acres or hectares. Everything is computed locally and deterministically, so it is instant and private. Ideal for gardening and landscaping apps, agriculture and horticulture tools, nursery and farm planners, and reforestation calculators. Pure local computation — no key, no third-party service, instant. Live, nothing stored. 3 endpoints. This is planting layout and density; for fertilizer application rates use a fertilizer API and for mulch, soil and gravel quantities use a landscaping API.
