## Notes

- Responses are GeoJSON with `Point` or `Polygon` geometries
- **Not all APIs are official** — Riksantikvaren notes some may change without notice. Official ones are listed on Geonorge.
- For large spatial queries, use bbox filtering to limit response size
- The `limit` parameter controls page size (default 10, max varies)
- Use `offset` for pagination through large result sets
