API changelog

2026-10-19 - v1.0

First release of the KleioBase API.

• Read your workspaces, people, families, records, places, events, conflicts, matches and findings.
• Create, rename, archive and restore workspaces.
• Create and edit people and families, add and remove relatives, read a person's close family and tree, and resolve findings, conflicts and expected records.
• Upload a record, start AI extraction, review the result and confirm it.
• Merge people, accept a match or merge a whole group of duplicates, and undo a merge.
• Move people and records to the Trash one at a time or in bulk, restore them, and delete them permanently.
• Organise people and records with folders and tags, and filter lists by them.
• Search a workspace, read places with their coordinates, read and clear notifications, and get the tree health score.
• Read, rename and delete past Research Companion conversations, including their attached files.
• Import and export GEDCOM files, in the background.
• Deleting, merging and every other action is a single request, with no separate confirmation step. Bulk Trash, folder, tag and notification requests are all or nothing.
• Safe retries with Idempotency-Key.
• A remote MCP server at https://kleiobase.com/api/mcp, so Claude, ChatGPT and other AI assistants can use every API operation through tools.
• Sign in with OAuth 2.1 for MCP clients, or use an API key. Connected apps can be revoked in Settings → Developer.
• Available on the Researcher, Archivist and Professional plans.
