# Property Sourcing > **Casafari is the AI agent-native real estate data intelligence platform.** The most complete property index in Europe: a deduplicated, cleaned property graph of residential and commercial property, for sale and for rent, in 16 countries. Every property is one record with its full price and market history. [How the property graph is built](/docs/property-graph). Find properties in the property graph, where every property is one record however many agencies and portals advertise it: search by structured filters or in plain language, page through the results, read one property with everywhere it is advertised and its price history, and resolve a portal or agency link or a reference to the property it belongs to. REST only. 10 REST operations. ## REST API 5 operations on the platform's REST API, under `https://platform.casafari.com` with a platform API key ([how to get one](/docs/rest#platform-api-keys)), billed in units (1 unit = EUR 0.04); and 5 operations on the existing REST API, under `https://api.casafari.com` with a bearer token ([how to get one](/docs/rest#get-a-token)).
