UUID API
A fast, fully-local identifier-generation toolkit: create UUID v4 (random), v7 (time-ordered and lexicographically sortable), v3 and v5 (name-based, deterministic via MD5 and SHA-1 over a namespace plus name) and the nil UUID; generate ULIDs (sortable, Crockford base32); generate nanoids (URL-safe, with custom alphabet and size); and validate any UUID, reporting its version and variant. Every endpoint accepts input via the query string or the request body. Built on Node crypto, no third-party upstream, so responses are instant and always available. Ideal for databases and primary keys, distributed systems, idempotency and correlation keys, and general developer tooling.

Hash API
Compute cryptographic hashes (MD5, SHA-1, SHA-256/384/512, SHA-3, RIPEMD-160) in hex or base64, generate HMAC signatures for webhook and message authentication, and mint v4 UUIDs. All server-side and deterministic. Handy for integrity checks, signing, cache keys, deduplication and id generation.

Quiz & Trivia API
A ready-to-use trivia engine with more than 44,000 multiple-choice questions across 20 categories — animals, brain teasers, celebrities, entertainment, kids, general knowledge, geography, history, hobbies, humanities, literature, movies, music, people, religion, science & technology, sports, television, video games and world. Pull a random question or a batch (optionally filtered by category, with the answer hidden for gameplay and the options shuffled), fetch a specific question by id, verify a submitted answer, search questions by keyword, and list every category with its question count. Every endpoint accepts input via the query string or the request body and returns lean JSON. Pure server-side data (no third-party upstream), so responses are instant and always available. Ideal for quiz and trivia games, pub-quiz and party apps, learning tools, chatbots and Discord/Slack bots.

Face Detection API
Detect human faces in an image and analyse each one with on-device machine learning: get the bounding box and a detection confidence, an estimated age, the predicted gender with its probability, and the dominant facial expression together with the full per-expression breakdown (neutral, happy, sad, angry, fearful, disgusted and surprised). A lightweight count endpoint returns just the number of faces and their boxes for fast gating. Supply an image by public URL, base64 or a raw binary request body; only public http/https URLs are accepted and private or internal hosts are blocked, and large images are downscaled automatically. Runs locally on TensorFlow (face-api) — no third-party upstream and no per-image cloud cost — with warm models that keep inference fast. Ideal for photo and avatar apps, audience analytics, smart cameras, auto-cropping and accessibility.

NSFW Detection API
Moderate images automatically with on-device machine learning. Classify any image across five categories — neutral, drawing, sexy, porn and hentai — and receive per-class probabilities, the top class, a combined NSFW score and a clear verdict (safe, questionable or nsfw). A simpler check endpoint returns a single safe/unsafe decision against a threshold you choose, ideal for upload gates and user-generated-content pipelines. Supply an image by public URL, base64 or a raw binary request body; only public http/https URLs are accepted and private or internal hosts are blocked, and large images are downscaled automatically. Runs locally on TensorFlow (NSFWJS / MobileNetV2) — no third-party upstream and no per-image cloud cost — with a warm model that keeps inference fast. Ideal for community platforms, marketplaces, dating and chat apps, and any service that accepts user images.
