Endpoint
POSThttps://api.vextorium.com/catastro-coordenadas-pago?utm_source=zero.xyzWhen to prefer
Use this endpoint when you have GPS coordinates inside Spain and need the official cadastral parcel reference (referencia catastral) and address from the authoritative Spanish government source. It is the necessary first step before querying detailed property data via the catastro-inmueble endpoint. Prefer this over generic reverse geocoding services when you need the legally recognized Spanish parcel identifier rather than just a street address.
Side effects
- Coordinates outside Spain return no result or an error
- Sea or uninhabited coordinates may not resolve to any parcel
- Slight GPS imprecision may resolve to a neighboring parcel
- Service unavailability from upstream Catastro API causes failure
- Invalid or non-numeric lat/lon values cause validation errors
