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.

Climbing Fall API
Rock-climbing fall maths as an API, computed locally and deterministically — the safety numbers behind a lead fall, from the harshness of the catch to whether you hit the deck. The fall-factor endpoint gives the fall factor, distance fallen ÷ rope paid out, from 0 to a maximum of 2: it, not the absolute distance, decides how hard the catch is, so 4 metres on 2 metres of rope is a brutal factor-2 onto the anchor while the same fall on 10 metres of rope is a mild 0.4. The impact-force endpoint gives the peak force the rope transmits from the spring model F = mg + √((mg)² + 2·mg·k·f), where k is the rope modulus (~20 kN for a dynamic single rope) and f the fall factor — so an 80 kg climber on a factor-1 fall feels about 6.4 kN, and the top runner sees roughly 1.66× that from the pulley effect. The ground-fall endpoint adds it up: total drop = twice the height above the last piece, plus slack, plus the rope's stretch, and tells you whether that clears the ground or a ledge. Everything is computed locally and deterministically, so it is instant and private. Ideal for climbing apps, gym and guiding tools, route-planning and education sites, and gear calculators. Pure local computation — no key, no third-party service, instant. Live, nothing stored. 3 compute endpoints. Educational estimates — not a substitute for instruction and judgement.

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.

Kite Flying API
Drachenflug-Mathematik als API, lokal und deterministisch berechnet – die Leinenzug-, Höhen- und Mindestwind-Zahlen, mit denen ein Drachenflieger, Festivalorganisator oder eine Drachen-App einen Flug plant. Der Leinenzug-Endpunkt gibt die Spannung an, die ein Drachen auf die Leine ausübt ≈ ½ × Luftdichte × Windgeschwindigkeit² × Segelfläche × Kraftkoeffizient (~0,8 für einen typischen Flach- oder Delta-Drachen): Da sie mit dem Quadrat des Windes steigt, vervierfacht eine Verdopplung des Windes den Zug – ein 1,5 m² Drachen hält etwa 47 N (fast 5 kgf) bei 8 m/s, aber das Vierfache bei einem starken Windstoß, daher müssen Leine und Griff auf die Böen ausgelegt sein, nicht auf den Durchschnitt. Der Höhen-Endpunkt gibt die Flughöhe = ausgelassene Leine × Sinus des Leinenwinkels über der Horizontalen, mit der Windabstand aus dem Kosinus: 100 m Leine bei einem 45°-Winkel erreichen etwa 71 m Höhe und 71 m windabwärts, während ein schwerer oder unterflogener Drachen in einem flachen Winkel hängt und nie steigt. Der Min-Wind-Endpunkt gibt den leichtesten Wind an, der abhebt, wo der aerodynamische Auftrieb gerade dem Gewicht entspricht: min Wind = √(2 × Masse × g ÷ (Luftdichte × Fläche × Auftriebskoeffizient)), also benötigt ein 200 g, 1,5 m² Drachen nur etwa 1,6 m/s (6 km/h) – leichtere Segel und größere Fläche senken die Schwelle. Alles wird lokal und deterministisch berechnet, also ist es sofort und privat. Ideal für Drachenflug- und Festival-Apps, Hobby- und MINT-Bildungswerkzeuge sowie Outdoor-Rechner. Reine lokale Berechnung – kein Key, kein Drittanbieter-Service, sofort. Flachdrachen-Schätzungen – kombinieren Sie mit echten Windmessungen. 3 Compute-Endpunkte. Für Luftwiderstand und Endgeschwindigkeit verwenden Sie eine Drag-API; für strukturelle Windlast eine Wind-Load-API.

Slackline Tension API
Tensioned-line point-load statics as an API, computed locally and deterministically — the line-tension and anchor-force numbers a slackliner, highliner or rigger works out before they weight a line. This is the V a loaded line makes under a person, not a self-weight catenary: the tension endpoint takes the span, the sag and the body load and returns the line tension and the horizontal anchor pull, because vertical balance is 2·T·sin(angle) = the body weight — so the flatter the line (the smaller the sag) the more the tension blows up, which is exactly why drum-tightening a line to kill the bounce can load the anchors to many times body weight. The sag endpoint inverts it: from a known line tension it returns the sag a mid-span load settles to (sin angle = weight ÷ twice the tension), and flags when the tension is too low to hold the load at all. The off-centre-load endpoint handles standing away from the middle, where the two halves carry different tensions: the horizontal pull is equal on both sides (H = weight × a × b ÷ (sag × span)) but the shorter, steeper segment runs at the higher tension and fails first — the reason a highliner near an anchor stresses that leash harder than one in the centre. Everything is computed locally and deterministically, so it is instant and private. Ideal for slackline and highline rigging tools, climbing and outdoor-gear apps, and tension-and-anchor calculators. Pure local computation — no key, no third-party service, instant. Geometric statics — combine with the real webbing and anchor ratings. 3 compute endpoints. For a self-weight hanging cable use a catenary API; for working-load-limit and safety factor a rigging API.
