There are four addressing products that make up our AddressBase product range, as well as the OS Places API
The differences between them include:
number of records
detail of attribution
how often you can receive updated data
how well you can link it to other data

Summary
The AddressBase products and Places API offer an accurate account of addressing for land and property features
Each product can be more suited to specific tasks than others. AddressBase Premium gives you the richest amount of addressing data, but will require extra processing for more simplistic tasks
Places API gives you the ability to see daily updates, so as soon as changes in the LLPG are sent to GeoPlace and processed, they will appear in the API, so for public facing applications this provides the most up-to-date data
