Install Almanac III Free Complete — all 150 tools $29/mo

Full REST API

Every operation in Almanac III is available through a JSON REST API. No SDK required — use curl, fetch, or any HTTP client.

Why this exists

The overhead of managing schemas tends to grow quietly until someone asks why the team is paying four different subscriptions for overlapping features. Almanac III replaces that stack with a single process that starts in under a second.

How it works

The data model stores each schema with 7 fields: name, database, table name, columns, description. All fields are queryable through the search API. The dashboard renders schemas as cards with inline metadata. Creating, editing, and deleting records is immediate — no save-and-deploy cycle.

A regulated company runs Almanac III inside their air-gapped network. No data leaves the building. Compliance auditors can inspect the SQLite file directly. When the team needs a report, they query the API and format the output however the auditor expects.
