Protocol Reference

Build institutional-grade property applications with the Casapi unified infrastructure. Our REST API handles the legal and jurisdictional complexity of the Mediterranean real estate market, delivering standardized data objects for Banks, Notaries, and PropTechs.

Authentication

Every institutional request requires an active API key and an Organization ID. Pass these in the headers to route your call to the correct jurisdictional silo.
