How limits are enforced
Usage counts events accepted into your space during the current usage period.- Free — the usage period is the calendar month (UTC). Once the 1,000-event allowance is used, further events are rejected during processing until the month resets. The ingest API still responds
202(limits are enforced asynchronously — see Delivery guarantees), but rejected events do not appear in the dashboard and are not billed. - Plus — the usage period is your plan month, the billing period that starts on your subscription date. The first 100,000 events per period are included; additional events are accepted and billed at $0.00028 per event.
