@MT0,
There are two options you can use the in-database geocoder PL/SQL package without the need to purchase and load third-party geocoding reference data:
With every Oracle Autonomous Database (https://oracle-livelabs.github.io/sprints/data-management/sprint-adb-geocode/)
With Oracle Spatial Studio (https://www.youtube.com/watch?v=yCxlNBjtoNE, https://docs.oracle.com/en/database/oracle/spatial-studio/24.2/spstu/geocoding-dataset.html)
