Bézier-curve geometry maths as an API, computed locally and deterministically. The point endpoint evaluates a quadratic (three control points) or cubic (four) Bézier curve at a parameter t between 0 and 1 using de Casteljau's algorithm, returning the point on the curve and the tangent there — its direction vector, angle and speed (the derivative B'(t)). The length endpoint computes the arc length of the curve by fine polyline sampling, together with the straight-line chord length and the axis-aligned bounding box (min and max x and y, width and height). The split endpoint splits the curve at a parameter into two sub-curves and returns the control points of each — the standard de Casteljau subdivision used for trimming and adaptive rendering. Control points are passed as plain x/y coordinates. Everything is computed locally and deterministically, so it is instant and private. Ideal for graphics, CAD, font, animation, game-engine and vector-design app developers, path and curve tools, and computational-geometry education. Pure local computation — no key, no third-party service, instant. Live, nothing stored. 3 endpoints. This is Bézier-curve geometry; for animation easing and timing functions use an easing API.

Complex-number maths as an API, computed locally and deterministically. The arithmetic endpoint adds, subtracts, multiplies or divides two complex numbers z₁ = a + bi and z₂ = c + di, returning the result in both rectangular (a + bi) and polar (modulus ∠ angle) form.

The linear endpoint interpolates between two points, y = y0 + (y1 − y0)·(x − x0)/(x1 − x0), returning the value at a target x (or, given a target y, solving the x that produces it), the parameter t and whether the point lies outside the segment. The table endpoint does piecewise-linear interpolation within a table of (x, y) points supplied as comma-separated lists — it sorts the points, finds the two that bracket your query and interpolates between them, extending the nearest segment and flagging the result when you query outside the data range, ideal for calibration curves and lookup tables.

The espresso endpoint does the same for espresso from any two of the dose, the yield and the brew ratio (yield = dose × brew ratio), labelling the shot ristretto, normale or lungo. The extraction endpoint computes the extraction yield, EY% = (beverage mass × TDS%) ÷ dose, from the dose, the brewed beverage mass (or the water, estimating the mass the grounds retain) and the measured total dissolved solids, then classifies the brew as under-extracted, ideal or over-extracted and weak through very strong against the SCA brewing control chart.

The doubling endpoint gives how long an investment takes to double at a given rate, both the exact figure ln(2)/ln(1+r) and the quick Rule-of-72, -70 and -69.3 estimates, or inverts it to the rate needed to double within a target time. The real-return endpoint applies the Fisher equation, real = (1+nominal)/(1+inflation) − 1, to strip inflation out of a headline return — or works backwards to the nominal return needed for a target real return — showing how the rough nominal-minus-inflation shortcut drifts at higher rates.

International Standard Atmosphere (ISA) maths as an API, computed locally and deterministically. The properties endpoint gives the air temperature, pressure, density and speed of sound at any altitude from sea level to 20 km — using the standard troposphere lapse rate (T = T0 − 0.0065·h) and the isothermal lower stratosphere above 11 km — along with the density, pressure and temperature ratios relative to sea level. The density-altitude endpoint computes the density altitude — the ISA altitude with the same air density — from a pressure altitude and the actual outside-air temperature, the figure pilots use because heat and low pressure rob an aircraft of lift, engine power and propeller thrust; it also reports the ISA temperature deviation.

El endpoint de conversión convierte un tamaño de datos entre unidades decimales (1 MB = 1,000,000 bytes) y binarias (MiB = 1,048,576), o una tasa de datos entre tasas de bits y tasas de bytes. Todo se calcula local y determinísticamente, por lo que es instantáneo y privado. Ideal para desarrolladores de redes, nube, respaldo y aplicaciones de streaming, herramientas de tiempo de descarga y planificación de capacidad, y paneles de desarrollo. Cálculo local puro — sin clave, sin servicio de terceros, instantáneo. En vivo, nada almacenado. 3 endpoints. Esto es tiempo de transferencia y ancho de banda; para tasa de bits de codificación de medios use una API de tasa de bits.
