Get a sync preview

GET
/sync/preview/{previewId}
curl --request GET \
  --url https://example.com/api/v1/sync/preview/example

Retrieves a previously generated preview snapshot by ID.

This endpoint is read-only and is safe to call repeatedly while preview state changes naturally over time.

Snapshots are subject to staleness rules enforced by the preview TTL. A preview that has exceeded the TTL should be treated as expired.
