Bucket a key

API de segmentación A/B
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.

Programming Languages API
The language definitions GitHub uses to recognise code (the open-source Linguist data) as an API — a clean reference for syntax highlighting, file-type detection, repository dashboards and developer tooling. For each of 800+ languages the API returns its type (programming, markup, data or prose), its brand colour (the hex GitHub paints it), the file extensions associated with it, common aliases, the GitHub language id and the editor (ace) mode. Look a language up by name or alias (golang resolves to Go), reverse-look-up which language(s) own a file extension (.py → Python; .h → C, C++, Objective-C), list the languages of a type, search, or list them all. Distinct from languages-api (ISO 639 human languages) — this is the programming-language reference. Served from memory — always fast.

MIME Types API
Die kanonische MIME-/Medientyp-Datenbank (die jshttp mime-db, die von Express und dem Großteil des Node-Ökosystems verwendet wird: IANA + Apache + nginx), aus dem Speicher bereitgestellt — kein Key. Lösen Sie einen Medientyp in seine Dateierweiterungen, Zeichensatz und Komprimierbarkeit auf; suchen Sie den/die Medientyp(en) für eine Dateierweiterung (z. B. png → image/png); und listen oder durchsuchen Sie Typen nach Quelle. 2.600+ Medientypen, 1.000+ mit Dateierweiterungen. Schlankes, vorhersagbares JSON. Ideal für Upload-Validierung, Content-Type-Auflösung, Dateityperkennung, Download-Handler und Entwicklerwerkzeuge.
