# Patch Kg Extraction Settings

`PATCH /api/workspace/kg-extraction/settings`

## Request

- Base URL: `https://api.dialogbrain.com` (the document declares no server; this is the origin it was published from)
- URL: `https://api.dialogbrain.com/api/workspace/kg-extraction/settings`
- Auth: none declared

Update kg_extraction_model and/or kg_extraction_fallback_policy.

Both fields are optional in the PATCH — caller can update either or
both. workspaces has a BEFORE UPDATE trigger (trg_workspaces_updated_at)
that maintains updated_at automatically.

Model storage: workspaces.settings JSONB key, matches the
`generate_model` pattern from /ai/generate-action so the same UI
persistence story applies.
