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.
