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.
