Rock-climbing grade conversion as an API, computed locally and deterministically — the cross-system grade translations a climber, gym or guidebook app needs when the same route reads differently in every country. The route endpoint takes a roped-climbing grade in any major system — the American Yosemite Decimal System (5.5 to 5.15d), French sport grades (4b to 9c+), the UIAA scale used across Central Europe (IV to XIII-) or the Australian/New Zealand Ewbank numbers (12 to 40) — and returns the equivalents in all of them, so a 5.11a is a French 6c, a UIAA VII+ and an Ewbank 22. The boulder endpoint converts between the American V-scale (VB and V0 to V17) and the French Fontainebleau scale (3 to 9A), so a V5 is Font 6C and a problem graded 7A is about V6. You can pass a grade in any supported system and it finds the row and gives the rest — handy for syncing a tick list across regions or showing a climber a grade they recognise. Everything is computed locally and deterministically, so it is instant and private. Ideal for climbing, bouldering, gym, guidebook and outdoor-sports app developers, tick-list and route-database tools, and training-log software. Pure local computation — no key, no third-party service, instant. Chart equivalents — grades are inherently approximate across systems. Live, nothing stored. 2 conversion endpoints.

GPA API
Calcule uma média ponderada de notas (GPA). O endpoint calc recebe uma lista de cursos — cada um com uma nota e os créditos que vale — e retorna o GPA ponderado por crédito, os totais e um detalhamento por curso dos pontos de qualidade para que você possa ver exatamente como a média foi formada. As notas podem ser letras do sistema americano (A, A-, B+, … F) na escala padrão 4.0, ou 4.3 com a escala us_plus que dá peso extra ao A+; porcentagens de 0 a 100 mapeadas para letras e pontos com os cortes usuais; pontos de nota brutos dados diretamente como números; ou seu próprio mapeamento personalizado de letra para ponto para qualquer esquema institucional. Os cursos podem ser passados como um array JSON ou uma string compacta como "A:3,B+:4,C:2", e os créditos padrão são 1 para uma média não ponderada. O endpoint scales lista as escalas de notas embutidas e seus valores de ponto. Tudo é calculado localmente e deterministicamente, então é instantâneo e privado — nenhum dado do aluno é armazenado. Ideal para planejadores e painéis de estudantes, portais de universidades e escolas, aplicativos LMS e ed-tech, ferramentas de bolsas e admissões, e calculadoras acadêmicas de cenários hipotéticos. Cálculo puramente local — sem chave, sem serviço de terceiros, instantâneo. Ao vivo, nada armazenado. 3 endpoints. Isso calcula GPA; para estatísticas gerais, use uma API de estatísticas.

Archery & Arrow API
Archery and arrow maths as an API, computed locally and deterministically — the FOC, energy and arrow-weight numbers an archer or bowhunter tunes a setup with. The FOC endpoint finds the front-of-center balance, the share of an arrow’s weight that sits forward of the middle: FOC = ((balance point − length ÷ 2) ÷ length) × 100 measured from the throat of the nock, so a 28-inch arrow balancing at 16 inches is 7.1 % — and it bands the result, since target archers run about 7–12 % while hunters push 12–19 % for penetration and forgiveness. The energy endpoint turns arrow weight and speed into terminal performance: kinetic energy (ft-lb) = grains × fps² ÷ 450,240 and momentum (slug-fps) = grains × fps ÷ 225,218, so a 400-grain arrow at 280 fps carries about 69.7 ft-lb and 0.50 slug-fps, with a suggested game class — momentum, not KE, is the better penetration predictor for heavy arrows. The weight endpoint totals a finished arrow from its parts — shaft (grains-per-inch × length) plus point, insert, nock and fletching — and divides by draw weight for grains-per-pound, flagging the 5-GPP minimum that protects the bow. Everything is computed locally and deterministically, so it is instant and private. Ideal for archery, bowhunting, traditional-archery and outdoor-sports app developers, arrow-builder and bow-tuning tools, and pro-shop calculators. Pure local computation — no key, no third-party service, instant. Imperial archery units. Live, nothing stored. 3 compute endpoints. For sight marks or bow tuning use a different API.

Tennis Score API
Tennis-Scoring-Mathematik als API, lokal und deterministisch berechnet – die Game-, Set- und Match-Logik, auf der eine Scoring-App, ein Schiedsrichter-Tool oder eine Tennisliga basiert. Der Game-Endpunkt spielt ein Game aus einer Sequenz, wer jeden Punkt gewonnen hat, und gibt das korrekte Tennis-Scoring zurück: Punkte laufen 0, 15, 30, 40 und dann Game, aber bei 40-40 ist es Einstand und ein Spieler muss mit zwei Punkten führen – Vorteil, dann Game – also ist a,a,a,a 40-0 und ein Sieg, während drei-gleich Einstand ist; ein Tiebreak-Flag zählt bis sieben mit zwei Punkten Vorsprung (und geht bei 7-7 weiter). Der Set-Endpunkt liest ein Set aus den Games, die jeder Spieler gewonnen hat: Ein Set ist bei sechs Games mit zwei Games Vorsprung gewonnen, 6-6 löst einen Tiebreak aus, der mit 7-6 endet, und 7-5 gewinnt, wenn ein Spieler zuerst in Führung geht. Der Match-Endpunkt entscheidet das Match aus den gewonnenen Sets – Best-of-Three wird durch zwei Sets entschieden, Best-of-Five durch drei – und sagt den Gewinner in dem Moment, in dem er erreicht ist. Alles wird lokal und deterministisch berechnet, daher ist es sofortig und privat. Ideal für Entwickler von Tennis-, Racketsport-, Scoring-, Schiedsrichter- und Liga-Apps, Scoreboard- und Live-Scoring-Tools sowie Club-Software. Reine lokale Berechnung – kein Key, kein Drittanbieter-Service, sofortig. Scoring-Logik, keine Analysen. Live, nichts wird gespeichert. 3 Compute-Endpunkte.

Bowling Score API
Ten-pin bowling maths as an API, computed locally and deterministically — the scoring, handicap and average numbers a bowler, league or scoring app runs on. The score endpoint plays a full game from a comma list of the pins knocked down on each roll and applies the real rules: a strike scores 10 plus your next two rolls, a spare 10 plus the next one, an open frame just the pins, with the 10th frame’s bonus rolls handled — so twelve strikes is a perfect 300, twenty 9-then-miss frames are 90, and all spares with a 5 bonus is 150, returned frame by frame with the running total. The handicap endpoint levels a league: handicap per game = ⌊(basis − average) × percent⌋, never below zero, so a 150 average on the common 90 %-of-220 setup earns 63 pins a game and 189 over a three-game series. The average endpoint divides total pins by games (dropping the fraction, as leagues do), rolls in a new series to update it, and works out the pins you need over the next games to reach a target average. Everything is computed locally and deterministically, so it is instant and private. Ideal for bowling-league, scoring, sports and recreation app developers, scorekeeping and handicap tools, and centre-management software. Pure local computation — no key, no third-party service, instant. Live, nothing stored. 3 compute endpoints.
