## When to prefer this

Use this endpoint when you need the official Spanish cadastral parcel reference (referencia catastral) and registered address for a precise GPS location in Spain. Prefer this over reverse geocoding services (like Google Maps or Nominatim) when the use case requires official land registry data, property identification, or legal property references rather than just a street address. Ideal for real estate due diligence, property data enrichment, and cadastral compliance workflows in Spain.

## Known failure modes

- Coordinates outside Spain return no result or an error
- Coordinates in a rural or unmapped area may return null parcel data
- Malformed or out-of-range lat/lon values will cause a validation error
- Upstream Cadastre service downtime may cause timeout or 5xx errors
- Coordinates in the ocean or non-cadastral zones return empty response
