API

Utility Endpoints The seven stateless utility endpoints under /api/json/utilities (hash, verify-hash, uuidv7-timestamp, ulid-timestamp, resolve-id, jcs-canonicalize, server-time) and their GraphQL query twins, with request and response shapes, the result envelope, auth and OAuth scopes, and resolve-id gating.

Cryptography

ULID and UUIDv7 Identifiers How Truestamp assigns identifiers - ULID for Item IDs and UUIDv7 for every other resource - both timestamp-prefixed and lexicographically sortable, stored as 128-bit binary in Postgres uuid columns.

Glossary

ULID The 26-character Crockford Base32, timestamp-prefixed, lexicographically sortable 128-bit identifier used exclusively for Truestamp Item IDs; every other resource uses UUIDv7, and both are stored as raw 16-byte binary in Postgres uuid columns.

Product

Global Search How the search page at https://www.truestamp.com/search auto-detects what you paste (26-character item ID, block/beacon/entropy UUID, 32-128 hex digest, or free text over names, descriptions, and tags) and returns grouped items, blocks, beacons, and entropy observations with team-aware visibility.
