Committed plans are better suited when the customer expects recurring monthly usage, larger historical downloads, frequent polling, or WebSocket streaming.
Caveat
This example assumes the historical data is downloaded in one day. Daily pricing tiers reset each day, so splitting downloads across multiple days can affect the total estimate.
