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.

Egg Incubation API
Egg-incubation maths as an API, computed locally and deterministically — the hatch timeline, conditions and brooder numbers a hatchery or backyard chicken-keeper raises a clutch by. The hatch endpoint turns the set day (day 0) into the schedule by species: it knows the incubation period — chicken 21 days, duck 28, quail 17, goose 30, turkey 28, Muscovy 35 and more — and gives the lockdown day, about three days before hatch, when you stop turning the eggs, raise the humidity and leave the lid shut; pass a custom incubation_days for anything else. The conditions endpoint gives the targets: a forced-air incubator at 99.5 °F (still-air a degree or two higher at the top of the eggs), with humidity around 45–55 % through incubation and 65–75 % at lockdown so the membrane stays soft. The brooder endpoint schedules the chicks after they hatch — 95 °F under the lamp in week one, dropping 5 °F a week until they reach room temperature around 70 °F and are feathered enough to leave it. Everything is computed locally and deterministically, so it is instant and private. Ideal for poultry, hatchery, homesteading and farm app developers, incubation-timer and brooder tools, and 4-H / education software. Pure local computation — no key, no third-party service, instant. Guidance — candle the eggs and watch the chicks. Live, nothing stored. 3 compute endpoints.

Vegetable Fermentation API
Vegetable lacto-fermentation maths as an API, computed locally and deterministically — the salt numbers a fermenter weighs sauerkraut, kimchi and pickles by. (Vegetables, not meat — for cure and nitrite that is a separate calculation.) Salt is the whole game: too little and the wrong microbes win, too much and the ferment stalls. The salt endpoint does the dry-salt method for shredded veg, salt = vegetable weight × percent, with about 2 % being the classic sauerkraut and kimchi target — so a kilo of cabbage takes 20 grams — and it bands the result from low-and-fast to a near salt-cure. The brine endpoint sizes a submerged ferment, salt = water weight × percent where the percent is of the water as recipes state it (1 ml water ≈ 1 g), so a litre at 5 % needs 50 grams for a standard sour pickle, 3.5 % for a milder one; it also reports the salinity as a percent of the total solution. The salinity endpoint converts the two ways the same brine is expressed — percent of water versus percent of total — so a 5 %-of-water brine reads about 4.76 % on a refractometer. Everything is computed locally and deterministically, so it is instant and private. Ideal for fermentation, homesteading, recipe and food app developers, ferment-calculator and batch tools, and culinary software. Pure local computation — no key, no third-party service, instant.

Home Canning API
Home-canning maths as an API, computed locally and deterministically — the altitude adjustments that keep a batch of preserves safe, the numbers a canner, homesteader or recipe app processes a jar by. Because water boils cooler the higher you are, every tested sea-level recipe has to run longer or hotter, and this API does that arithmetic. The waterbath endpoint applies the USDA boiling-water-bath and steam-canner rule: for a base process of 20 minutes or less add 5, 10, 15 or 20 minutes by altitude band, and for more than 20 minutes add 10, 20, 30 or 40 — so a 15-minute pickle recipe at 4,000 feet processes 25 minutes, and a 30-minute one runs 50. The pressure endpoint adjusts the canner: a dial gauge gains 1 psi per 2,000 feet, turning an 11 psi recipe into 12, 13, 14 or 15, while a weighted gauge simply steps from 10 psi up to 1,000 feet to 15 above it, since it only has 5/10/15 settings. The boilingpoint endpoint gives the underlying reason — water boils about 1.84 °F lower per 1,000 feet, so 5,000 feet boils at 202.8 °F instead of 212. Everything is computed locally and deterministically, so it is instant and private. Ideal for canning, food-preservation, homesteading, recipe and kitchen app developers, preserving-calculator and pantry tools, and cooking-class software. Pure local computation — no key, no third-party service, instant. USDA tables — always follow a tested recipe. 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.
