Catering & Party API

healthy 4,088 Subscribers

Catering and party-planning maths as an API, computed locally and deterministically — the how-much-do-I-buy numbers a host or caterer plans a headcount with. The food endpoint scales a menu to the guest count and appetite: the main protein at about half a pound of cooked meat per person (light 0.33, hearty 0.75), each side dish at roughly four ounces a head, six appetizer pieces each and one-and-a-half dinner rolls — so 50 guests at a standard dinner with three sides need 25 lb of meat, 300 appetizers and 75 rolls. The drinks endpoint sizes the bar: about one drink per guest per hour plus an extra in the first hour, split across beer, wine and cocktails, and converted into the real units you buy — beer by the case (24) and the half-keg (~165 servings), wine by the bottle (~5 glasses), spirits by the 750 ml bottle (~16 shots) — plus the ice (about 1.5 lb per guest) and water; a 50-guest, four-hour party comes to 250 drinks, 125 beers (0.76 of a keg), 15 bottles of wine and 75 lb of ice. Everything is computed locally and deterministically, so it is instant and private. Ideal for event-planning, catering, hospitality and party app developers, shopping-list and headcount tools, and host calculators. Pure local computation — no key, no third-party service, instant. US units; rules of thumb — round up. Live, nothing stored. 2 compute endpoints. Adjust for the crowd and the season.

Food Cost API

Restaurant food-costing maths as an API, computed locally and deterministically — the menu-engineering and cost-control numbers a kitchen runs on. The recipe endpoint totals a dish from its ingredient line costs (or quantities × unit prices), divides by the yield factor (1 − waste %) so trim and shrinkage raise the true cost, and splits it across the portions to a cost per plate — and against a menu price it returns the food-cost percentage and gross profit. The plate endpoint prices a dish both ways: give a menu price and get the food-cost percentage and markup factor, or give a target food-cost percentage and get the suggested menu price (a 30 % target is a 3.33× markup), plus gross profit, gross margin and, with a labour cost, the prime-cost percentage. The period endpoint turns inventory movement into the cost of goods sold — COGS = opening inventory + purchases − closing inventory — and the food or pour cost percentage against sales, the headline number on every P&L (28–35 % for food, 18–24 % for beverage). Everything is computed locally and deterministically, so it is instant and private. Ideal for restaurant-tech, POS, kitchen-management, catering and hospitality app developers, menu-engineering and recipe-costing tools, and culinary-school training. Pure local computation — no key, no third-party service, instant. Live, nothing stored. 3 compute endpoints. This is food-cost and menu-pricing maths; for unit conversion use a cooking API and for generic margin maths a pricing API.

Candy Temperature API

Candy-making maths as an API, computed locally and deterministically — the sugar-syrup stage numbers a confectioner reads a thermometer by. As sugar syrup boils it passes through named stages, each a temperature window with its own texture and uses, and getting within a few degrees is the difference between fudge and toffee. The stage endpoint names the stage for a temperature: 238 °F is the soft-ball stage (fudge, fondant, pralines), 305 °F is hard-crack (toffee, brittle, lollipops), and it handles °F or °C and the off-the-chart cases — still a thin syrup below thread, or darkening to burnt past caramel. The range endpoint gives the temperature window and uses of a named stage, from thread (223–234 °F) through soft-ball, firm-ball, hard-ball, soft-crack and hard-crack to caramel (320–350 °F), in both °F and °C. The altitude endpoint applies the rule that matters in the mountains: cook to 1 °F lower for every 500 feet of elevation, since water boils cooler, so a 300 °F hard-crack recipe is done at 290 °F at 5,000 feet. Everything is computed locally and deterministically, so it is instant and private. Ideal for baking, confectionery, recipe and kitchen app developers, candy-thermometer and timer tools, and cooking-class software. Pure local computation — no key, no third-party service, instant. Use a calibrated thermometer. Live, nothing stored. 3 compute endpoints.

Window Tint API

Window-tint maths as an API, computed locally and deterministically — the net VLT numbers an installer or car owner picks a film by. The catch with tint is that visible light transmission multiplies through layers: factory automotive glass already passes only about 70–80 % of light, so a film’s rated VLT is not what you end up with. The vlt endpoint multiplies it out — net % = the product of each layer’s VLT ÷ 100 — so a 35 % film on 78 % factory glass nets 27.3 %, a 5 % limo film on the same glass nets 3.9 %, and you can stack several layers in one call; it also describes how dark that looks, from near-clear down to blackout. The required endpoint runs it backwards: to land on a target net VLT through known glass you need a film of target ÷ glass × 100, so hitting a 35 % net on 78 % glass takes a 44.9 % film — and it flags the impossible case where the target is lighter than the bare glass already allows. Everything is computed locally and deterministically, so it is instant and private. Ideal for auto-tint, detailing, glass and automotive app developers, film-selection and compliance tools, and shop software. Pure local computation — no key, no third-party service, instant. Legal limits vary by jurisdiction — check local law. Live, nothing stored. 2 compute endpoints.

Yahtzee Score API

Yahtzee scoring maths as an API, computed locally and deterministically — the category scores and totals a dice-game scoring app runs on. (It scores a given roll; it does not roll the dice.) The score endpoint takes five dice and returns the value of every one of the thirteen boxes at once: the upper boxes (ones through sixes) score the sum of that number, three- and four-of-a-kind and chance score all five dice, a full house is 25, a small straight (four in a row) 30, a large straight (five in a row) 40 and a Yahtzee (five of a kind) 50 — so 3-3-3-5-6 is worth 20 in three-of-a-kind, 4-4-4-5-5 is a 25-point full house, and it flags the highest-scoring box for you. The total endpoint adds up a finished card: the 35-point upper-section bonus when the upper boxes reach 63 (and how many points you still need for it), plus 100 for each extra Yahtzee, to give the grand total. Everything is computed locally and deterministically, so it is instant and private. Ideal for dice-game, board-game-companion, family-game and scorekeeping app developers, score-sheet and tournament tools, and game software. Pure local computation — no key, no third-party service, instant. Live, nothing stored. 2 compute endpoints. For random rolls use a dice API.
