Q:What happens if I hit my Streams or API limits?

If you have the Pro, Business, or Enterprise plan, you can continue to use Streams and APIs even if you exceed your plan’s limit. We will automatically scale your service and charge per million extra API compute units and/or per 10k extra Streams records. Automatic scaling charges vary by plan.

The Starter plan has daily limits. If you hit your daily limits, you can either wait for them to reset, or upgrade your plan to increase your limits instantly.
