Towing Calculator API
Trailer-towing weight maths as an API, computed locally and deterministically. The tongue endpoint computes the tongue (hitch) weight as a percentage of the loaded trailer weight and reports the recommended 10–15 % range — too little tongue weight is the main cause of trailer sway. The capacity endpoint computes the maximum trailer weight a tow vehicle can pull, GCWR − curb weight − payload (the passengers and cargo in the vehicle), and checks a proposed trailer against it with the margin remaining. The payload endpoint computes the vehicle payload still available once the trailer is hitched, GVWR − curb weight − tongue weight, since the tongue weight presses down on the tow vehicle and counts against its payload rating. Everything is computed locally and deterministically, so it is instant and private. Ideal for RV, caravan, trailer and fleet apps, tow-vehicle matching and load-planning tools, and automotive calculators. Pure local computation — no key, no third-party service, instant. Live, nothing stored. Guidance only — follow the manufacturer's ratings. 3 endpoints. This is trailer-towing weights; for tyre size and rolling circumference use a tyre API.

Window Tint API
Window-Tint-Mathematik als API, lokal und deterministisch berechnet – die Netto-VLT-Werte, nach denen ein Installateur oder Autobesitzer eine Folie auswählt. Der Haken bei Tönung ist, dass die sichtbare Lichtdurchlässigkeit durch Schichten multipliziert wird: Werksautoglas lässt bereits nur etwa 70–80 % des Lichts durch, daher entspricht die angegebene VLT einer Folie nicht dem, was am Ende herauskommt. Der vlt-Endpunkt multipliziert es aus – netto % = das Produkt der VLT jeder Schicht ÷ 100 – also ergibt eine 35 %-Folie auf 78 %-Werksglas 27,3 %, eine 5 %-Limo-Folie auf demselben Glas 3,9 %, und Sie können mehrere Schichten in einem Aufruf stapeln; er beschreibt auch, wie dunkel das aussieht, von fast klar bis abgedunkelt. Der erforderliche Endpunkt rechnet rückwärts: Um eine Ziel-Netto-VLT durch bekanntes Glas zu erreichen, benötigen Sie eine Folie von Ziel ÷ Glas × 100, also erfordert das Erreichen einer 35 %-Netto-VLT auf 78 %-Glas eine 44,9 %-Folie – und er kennzeichnet den unmöglichen Fall, wenn das Ziel heller ist als das bloße Glas bereits erlaubt. Alles wird lokal und deterministisch berechnet, daher ist es sofort und privat. Ideal für Auto-Tönung, Fahrzeugveredelung, Glas- und Automobil-App-Entwickler, Folienauswahl- und Compliance-Tools sowie Werkstattsoftware. Reine lokale Berechnung – kein Key, kein Drittanbieter-Service, sofort. Gesetzliche Grenzwerte variieren je nach Rechtsordnung – prüfen Sie lokale Gesetze. Live, nichts wird gespeichert. 2 Compute-Endpunkte.

Tire Size API
Tyre-size geometry as an API, computed locally and deterministically. The dimensions endpoint parses a metric tyre code such as 205/55R16 — or separate width, aspect ratio and rim values — into its full geometry: the sidewall height (width·aspect/100), the overall diameter (rim·25.4 + 2·sidewall) in millimetres and inches, the rolling circumference, and the revolutions per kilometre and per mile; a 205/55R16 works out to a 112.75 mm sidewall and a 631.9 mm (24.88 in) outside diameter. The compare endpoint takes an original and a replacement size and computes the speedometer error and ground-clearance change of swapping between them: because the speedometer is calibrated to the original rolling diameter, a larger tyre makes it read low, so true speed = indicated · OD_new/OD_old, and a tyre that is 2 % bigger means an indicated 100 is really about 102 km/h. Staying within ±3 % keeps the error and clearance change small. Tyre codes use the metric P-metric/Euro-metric form. Everything is computed locally and deterministically, so it is instant and private. Ideal for automotive, tyre-shop, fitment, car-enthusiast, fleet and vehicle-spec app developers, plus-sizing and speedo-error tools, and garage software. Pure local computation — no key, no third-party service, instant. Live, nothing stored. 2 endpoints. This is metric tyre geometry; for fuel economy use a fuel-economy API.

API de Frenado de Vehículos
Física de frenado de vehículos como API, calculada local y determinísticamente. El endpoint de distancia de frenado calcula la distancia total para detener un vehículo como la suma de la distancia de reacción que el vehículo recorre durante el tiempo de reacción del conductor, v·t, y la distancia de frenado v²/(2·μ·g) — que crece con el cuadrado de la velocidad, por lo que duplicar la velocidad cuadruplica la distancia de frenado — a partir de la velocidad, el coeficiente de fricción neumático-carretera, el tiempo de reacción y la pendiente de la carretera, junto con la desaceleración y el tiempo hasta detenerse. El endpoint de fuerza de frenado calcula la fuerza de frenado F = m·a y la desaceleración de un vehículo, ya sea a partir de una parada en una distancia dada (a = v²/2d) o del coeficiente de fricción (a = μ·g), con la energía cinética que debe disiparse como calor. El endpoint de velocidad de derrape reconstruye la velocidad al inicio de un derrape a partir de la longitud de la marca de derrape, v = √(2·μ·g·d), una estimación de límite inferior utilizada en reconstrucción de accidentes. La velocidad está en km/h por defecto (también m/s o mph), la masa en kg y las distancias en m; el asfalto seco tiene μ ≈ 0.7, mojado ≈ 0.4 y hielo ≈ 0.1. Todo se calcula local y determinísticamente, por lo que es instantáneo y privado. Ideal para desarrolladores de aplicaciones automotrices, de seguridad vial, flotas, telemática y reconstrucción de accidentes, herramientas de distancia de frenado y forenses, y educación en física. Cálculo local puro — sin clave, sin servicio de terceros, instantáneo. En vivo, nada almacenado. 3 endpoints. Esto es frenado de vehículos; para cinemática general use una API de cinemática y para un objeto en una pendiente use una API de plano inclinado.

Engine Displacement API
Internal-combustion engine maths as an API, computed locally and deterministically. The displacement endpoint computes an engine's swept volume from the bore, the stroke and the number of cylinders, V = (π/4)·bore²·stroke per cylinder, in cubic centimetres, litres and cubic inches, and classifies the bore-to-stroke geometry as oversquare, square or undersquare. The compression endpoint relates the compression ratio and the clearance volume, CR = (swept + clearance)/clearance — give the clearance to get the ratio or the ratio to get the clearance — and, with a boost pressure, estimates the effective compression ratio of a forced-induction engine. The power-to-weight endpoint computes the power-to-weight ratio in horsepower per tonne, kilowatts per tonne and watts per kilogram, the weight per horsepower, and, with a displacement, the specific output in horsepower per litre. Bore and stroke are in millimetres, volumes in cc, weight in kilograms and power in horsepower or kilowatts. Everything is computed locally and deterministically, so it is instant and private. Ideal for automotive, motorsport, motorcycle and engine-builder app developers, build-spec and tuning tools, and mechanical education. Pure local computation — no key, no third-party service, instant. Live, nothing stored. 3 endpoints. This is engine geometry and tuning; for EPA fuel-economy data use a fuel-economy API and for tyre sizes a tyre-calculator API.
