Access the Revenue Agency’s market and rental values directly within your software using a fast, secure, and scalable infrastructure.
The OMI Real Estate Quotations API provides access to the entire Italian Real Estate Market Observatory (OMI) database.
It allows you to query in real time the minimum and maximum values per square meter (for both sales and rentals) simply by providing geographical coordinates.
Specifically, it identifies the official OMI zone (Real Estate Market Observatory) whose polygon contains the specified point, then returns the details of the area, its geometry, and all available valuation bands (sales and rentals, broken down by property type and condition) for that zone.
The Endpoint returns the following information:
- Latest half-year values
- Region
- Province
- ISTAT Code
- OMI zone name
- Property type
- Min and Max Sale price (for all property types)
- Min and Max Rental value (for all property types)
