The RADEA.IO API allows a software developer to create a custom dashboard, user interface, or even a totally new application, all this independent of the default RADEA.IO web user interface.
When the RFID tagged items are read with a reader, this data is written into a data format called a "processlist" - which is the format RADEA.IO takes readings in - and sent to RADEA.IO. Once RADEA.IO receives the processlist it analyzes it, looks what tags (and thus items) are present in the reading and sets the state of them accordingly. Each reader (fixed reader - other reader kinds such as mobile readers might take a dynamic configuration) is assigned a "location" which is an identifier in RADEA.IO of where something is. The processlist contains this information and RADEA.IO can therefore tell you that the read items are now in the location where the processlist came from.
After RADEA.IO has received and analyzed the processlist, it updates all relevant states and info. This process happens in real-time. Afterward, you can query the RADEA.IO APIs for the location of the individual items or the inventories of the locations.
