Create a root or nested Hjarni container for organizing notes.

Create a Markdown note in the inbox or a container. Tags named in tag_names are applied as part of creation. Free accounts are limited to 25 notes, so check account status if quota pressure is possible.

Create 1-25 Markdown notes in order and return one result per input. This batch is non-atomic: successful notes remain created if another item fails.

Create a Hjarni tag for organizing notes.

Return the connected Hjarni identity, token scope, plan, teams, and current resource usage and quotas. Use this before creating many notes or attachments; Free accounts allow 25 notes, 5 attachments, and 20 MB of attachment storage.

Get one Hjarni note by ID with its Markdown body, tags, container, attachments, links, and optimistic-lock version.

List Hjarni containers as active roots, archived roots, or all active containers in a flat view. Use next_cursor to page through results.

List and filter personal Hjarni notes, including active, inbox, archived, or favorited notes. Use next_cursor to page through results; use query for simple personal-note filtering.

List all Hjarni tags and their note counts. Use next_cursor to page through results.

List recoverable trashed Hjarni notes with their deletion and scheduled purge times. Use next_cursor to page through results.

Rename an existing Hjarni tag without changing its note associations.

Restore a note from Trash before its scheduled purge and return the active note.

Move a note to recoverable Trash. This is not immediate permanent deletion: Hjarni retains the note for about 30 days, and RESTORE_NOTE can recover it before purge.

Update a Hjarni container's name, description, parent, position, or container-specific AI instructions.

Update note metadata, placement, tags, or body. body replaces the entire Markdown body; append_body safely appends text. Provide expected_lock_version from GET_NOTE to prevent overwriting concurrent edits.
