# Registry change feed

`GET /api/registry/feed`

Poll a cursor-based feed of registry changes. Events are ordered by UUID v7 event_id for monotonic cursor progression. The feed retains events for 90 days. The `freshness` object reports when the response was generated, the newest matching event currently visible to the feed, and the resulting feed lag.

Type filtering supports glob patterns: `property.*` matches `property.created`, `property.updated`, etc.

## Query parameters

- `cursor` string, uuid — Resume after this event ID
- `types` string — Comma-separated event type filters with glob support (e.g. property.*)
- `limit` integer — Max events per page (default 100, max 10,000)

## Response `200`
