What it returns

The history of an ENS name ending ".eth" (Basenames such as jesse.base.eth included) on the chain asked: every transaction that touched it, newest first, from its registration through renewals, transfers and changes to its records. name-resolution answers what the name points to now; this answers how it got there. ENS names registered on ETH have their history on ETH; Basenames on BASE. A name nobody registered, or one nothing touched on the chain asked, answers an empty events list. The name is case-insensitive.
