Alien Profile Information Database

The Alien Profile Information Database, shortened API Base or simply API, was a database created by ONI to store all information on aliens of intrest. The Database's main server was located in Sidney, Earth but several off-world servers were maintained across Human Space. It was first proposed in 2527 and accepted for implentation the year after in late 2528. API was completed in early 2529 and collected all gathered data on Covenant personal into a single server. The database was primarily used by ONI operatives tasked with assassination of Covenant personal and identification of said targets during the Human-Covenant War though it was also used by UNSC officers in the event that they believed that they were dealing with a particular Covenant commander or exceptional dangerous individual.

To keep the various databases up-to-date as much as possible, the many servers were updated by encrypted transmissions from automated freighters that transported people and goods across the colonies.
