In one line

Custom and partner events bill on ingestion. AWS service events land on the default bus for free.

What gets missed

A 200KB event is four billed events because each 64KB chunk counts as one, and Schema Discovery slices at 8KB. API destinations, Pipes and Scheduler invocations each carry their own per-million rate.

Bills the same way

These services turn exactly the same meters, so what you learn here transfers.
