Abstract: A method for determining status of events collected in records includes retrieving a group of records of respective events from an events database. The method includes extracting records from the group of records to generate a subgroup of records and storing the subgroup of records temporarily at a memory of a computer system.

Responsive to requests, the API serially processes respective records of the subgroup of records by comparing each record in the subgroup of records against indications of completed events. The method includes performing a self-executing action based on an output of the API including an indication of a status of a particular event in the subgroup of records. In one example, the status indicates that the particular event is complete or incomplete.
