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.

Equine Care API
Pferdepflege-Mathematik als API, lokal und deterministisch berechnet – die alltäglichen Zahlen, die ein Pferdebesitzer, Stallmanager oder Tierarzthelfer berechnet, ohne nach einer Tabelle greifen zu müssen. Der Gewichts-Endpoint schätzt das Körpergewicht aus einer Gewichtsbandmessung mit der klassischen Formel Gewicht ≈ Brustumfang² × Körperlänge ÷ einem Typ-Divisor (erwachsen 330, Jährling 301, Absetzer 280, Pony 299) mit Maßen in Zoll – ein Pferd mit 72 Zoll Brustumfang und 66 Zoll Länge ergibt etwa 1.037 lb (470 kg), die Zahl, nach der Sie tatsächlich Wurmkur und Futter dosieren. Der Futter-Endpoint setzt Körpergewicht und ein Ziel in tägliches Raufutter um: Pferde fressen etwa 1,5–2,5 % ihres Körpergewichts an Trockenmasse-Raufutter pro Tag, also ein 1.000 lb schweres Pferd zur Erhaltung benötigt etwa 15–20 lb Heu, mehr zum Zunehmen und weniger zum Abnehmen. Der Trächtigkeits-Endpoint gibt das voraussichtliche Fohlen-Datum und das normale 320–362-Tage-Fenster aus einem Deckdatum – eine Stute, die am 1. April gedeckt wurde, ist um den 7. März des nächsten Jahres fällig, plus/minus drei Wochen. Alles wird lokal und deterministisch berechnet, also sofort und privat. Ideal für Stallmanagement- und Pferdepflege-Apps, Zucht- und Fohlen-Tracker, Futterrechner- und Sattelkammer-Websites sowie equine Tierarzt-Tools. Reine lokale Berechnung – kein Key, kein Drittanbieter-Service, sofort. Live, nichts gespeichert. 3 Compute-Endpoints. Bildungsbezogene Schätzungen – kein tierärztlicher Rat.

Darkroom API
Analog darkroom and film maths as an API, computed locally and deterministically — the three corrections that bite when you develop film and make prints by hand. The reciprocity endpoint corrects long exposures for reciprocity failure, where film loses sensitivity past about a second: corrected time = metered^p (Schwarzschild p ≈ 1.3 for many films, settable per datasheet), so a metered 10-second exposure really wants about 20 seconds, a full stop more, while anything under the threshold is left untouched. The printexposure endpoint adjusts enlarger exposure when you change print size — light spreads as you raise the head, so exposure is proportional to (magnification + 1)², where magnification is print size ÷ negative size: going from 2× to 4× magnification turns a 10-second exposure into 27.8 seconds, about 1.5 stops, ready for f-stop printing. The pushpull endpoint scales development time for pushing or pulling film by N stops — time = base × factor^stops, roughly +40 % per stop pushed — turning a 7-minute base into 13.7 minutes at +2 stops, or 5 minutes pulled a stop. Everything is computed locally and deterministically, so it is instant and private. Ideal for film-photography and darkroom apps, light-meter and timer companions, lab and workshop tools, and analog-photography sites. Pure local computation — no key, no third-party service, instant. Live, nothing stored. 3 compute endpoints. For digital depth-of-field use a photography API; for lab molarity use a dilution API.
