Frequently asked questions

Is there an official cadastre API in Bulgaria?

The official data is published by the Bulgarian Geodesy, Cartography and Cadastre Agency (INSPIRE), through its own services with their own formats, reference systems and limits. Catastro GPS reads those services and gives you one REST/JSON API with an API key, WGS84 coordinates ready for a map and the same response in 29 countries.

How is a parcel identified in Bulgaria?

With the cadastral identifier: EKATTE code, cadastral area and parcel (for example 68134.100.2). If you do not have it, search by coordinates or by address and the API returns the reference together with the outline.

How much does it cost?

250 calls a month are free, forever and without a card. Paid plans: Developer €19 a month (5,000 calls), Startup €49 a month (15,000 calls), Growth €99 a month (50,000 calls). Lookups without a result do not count.

What does a response contain?

The reference, the country, the GPS point (latitud, longitud), the outline (poligono) and the area in m² (superficieParcela), plus the municipality where the source gives it. availableFields says which optional fields each answer really carries.

Can I search by address in Bulgaria?

Yes. /api/search/address/candidates?country=BG geocodes the address with OpenStreetMap and returns the parcel under it, ranked by a confidence from 0 to 1.
