Pruebas A/B deterministas y asignación de feature flags — sin base de datos, sin estado almacenado. El endpoint de bucket hashea una clave (un id de usuario, sesión o dispositivo) en un bucket estable de 0 a N-1 que nunca cambia para esa clave, y puede decidir si la clave está dentro de un despliegue porcentual; como la decisión es monótona, aumentar el porcentaje solo añade usuarios, por lo que una rampa gradual es persistente y nadie retrocede. El endpoint de variante asigna una de varias variantes ponderadas — una división simple de control/tratamiento o cualquier prueba multivariante — de manera consistente para la misma clave, respetando pesos personalizados. Mezclar un nombre de experimento mantiene los experimentos independientes entre sí, y como las mismas entradas siempre producen la misma respuesta, tu cliente y servidor (y cualquier función edge) coinciden en la asignación sin necesidad de coordinación ni búsquedas. El hashing es FNV-1a con una mezcla de avalancha, lo que proporciona buckets uniformes y estables en todos los lenguajes y máquinas. Se ejecuta completamente en local, por lo que es instantáneo, determinista y privado. Ideal para feature flags y despliegues graduales, experimentos A/B y multivariantes, lanzamientos canary, holdouts y kill-switches, y segmentación consistente de UI en web y móvil. Cálculo puramente local — sin clave, sin servicio de terceros, instantáneo. En vivo, nada almacenado. 3 endpoints. Esto asigna experimentos de manera determinista; para probar si un resultado es estadísticamente significativo, usa una API de estadísticas.

Birthday Paradox API
Birthday-paradox and collision-probability maths as an API, computed locally and deterministically. The probability endpoint computes the chance that at least two of n people share a birthday among d equally likely days, P = 1 − Π(1 − i/d), evaluated in log space for accuracy — the famous result that just 23 people give about a 50.7 % chance, 50 people about 97 % and 70 people about 99.9 %. The people-needed endpoint inverts it: the smallest group size to reach a target probability (23 for 50 %, 57 for 99 %), with the √(2·d·ln(1/(1−p))) approximation. The collision endpoint generalises the birthday bound to any space — pass a number of buckets or a hash size in bits — and returns the collision probability P ≈ 1 − e^(−n²/2d), the rule behind hash collisions and UUID-uniqueness estimates, where a 50 % chance needs roughly 1.177·√d items. Days and buckets default to 365. Everything is computed locally and deterministically, so it is instant and private. Ideal for probability-education, security, cryptography, hashing, data-engineering and statistics app developers, collision-risk and birthday-problem tools, and teaching material. Pure local computation — no key, no third-party service, instant. Live, nothing stored. 3 endpoints. This is the birthday/collision probability; for full distributions use a probability API.

Checksum API
Fast non-cryptographic checksums as an API. Compute CRC-32 — the integrity check used by ZIP, gzip, PNG and Ethernet — and Adler-32 — the checksum used by zlib — over UTF-8 text, hex or base64 input, returned in hex and as signed and unsigned 32-bit integers. Ideal for file- and message-integrity verification, cache keys and ETags, change detection and deduplication, where you want a quick fingerprint rather than a secure hash. Pure local computation — no key, no third-party service, instant; send binary via the hex or base64 encoding (up to 4 MB). Live, nothing stored. 4 endpoints. Explicitly NOT for security — for cryptographic digests (MD5, SHA-256, HMAC) use a hashing API instead.

Aquascape API
Pflanzenaquarium- und Aquascaping-Mathematik als API, lokal und deterministisch berechnet – die Dosis- und Wasserwerte, auf denen ein High-Tech-Pflanzentank läuft, nicht die Würfel eines Spiels. Der CO2-Endpunkt gibt die gelöste CO2-Konzentration aus pH und Karbonathärte unter Verwendung der klassischen Beziehung CO2 (ppm) ≈ 3 × KH (dKH) × 10^(7 − pH) und kennzeichnet sie gegenüber dem von Pflanzen gewünschten Fenster von 15–30 ppm – bei pH 6,6 und KH 4 liegen Sie bei etwa 30 ppm, dem oberen Ende der sicheren Zone, während pH 7,0 und KH 3 ein kohlenstofflimitiertes 9 ppm ergeben. Der Dünger-Endpunkt wandelt eine Trockensalzdosis in den Nährstoff-ppm, den sie hinzufügt, das Herz der Estimative-Index-Dosierung: ppm = Gramm × Nährstoffmassenanteil × 1000 ÷ Tankliter, also fügt 1 g KNO3 in 100 Litern 6,1 ppm Nitrat und 3,9 ppm Kalium hinzu, und er kennt KNO3, KH2PO4, K2SO4, MgSO4 (Bittersalz) und Ca(NO3)2. Der Substrat-Endpunkt dimensioniert das Substrat aus Grundfläche und Zieltiefe – ein 60 × 30 cm Tank bei 6 cm Tiefe benötigt 10,8 Liter, zwei 9-Liter-Aquasoil-Beutel. Alles wird lokal und deterministisch berechnet, also ist es sofort und privat. Ideal für Aquascaping- und Pflanzentank-Apps, Düngerrechner, CO2-Anlagen-Tools sowie Aquariengeschäfts- und Hobbyseiten. Reine lokale Berechnung – kein Key, kein Drittanbieterdienst, sofort. Live, nichts gespeichert. 3 Compute-Endpunkte. Für ein Tankwasservolumen oder Fischbesatz verwenden Sie eine Aquarium-API; für Poolchemie verwenden Sie eine Pool-API.

Reptile Husbandry API
Reptile-husbandry maths as an API, computed locally and deterministically — the keeper numbers behind a healthy vivarium, so the setup is right before the animal moves in. The enclosure endpoint turns an animal length and its habit into the minimum floor length, width and height: terrestrial snakes want a floor at least as long as the snake (a 48-inch corn snake → a 48 × 24 × 24 inch minimum, eight square feet of floor), arboreal species trade floor for height (an 18-inch chameleon → 27 × 18 × 36 inches, tall), and ground lizards and tortoises need far more floor than their body length. The uvb endpoint gives the UV-B target by Ferguson zone — the 1-to-4 classification from Baines et al. (2016) of how much sun a species basks in — returning the mean and basking UV-index ranges (zone 3 open baskers want a basking UVI of 2.9–7.4), and, if you pass a lamp UVI measured at a reference distance, an inverse-square estimate of the mounting distance for the right basking UVI. The feeding endpoint sizes prey from body weight and life stage: a meal of roughly 10–15 % of body weight, no wider than the animal, on an interval that lengthens with age — a 500 g adult snake takes a 40–60 g prey item every fortnight. Everything is computed locally and deterministically, so it is instant and private. Ideal for reptile-keeper and herpetoculture apps, pet-store and breeder tools, vivarium-planning calculators, and care-sheet sites. Pure local computation — no key, no third-party service, instant. Live, nothing stored. 3 compute endpoints. Educational husbandry estimates — not veterinary advice; research your exact species.
