You will receive a notification email when you reach 85% of your paid plan quota. If you hit the limit, your API / integrations will stop working.
If you need more credits, the best bet is to upgrade your plan ↗ or wait until your quota resets on the 1st of the following month. It's not possible to reset your quota manually.
Subscribing to a higher plan will be pro-rated and the amount will depend on how close you are to your billing cycle. Stripe will automatically compute and provide the amount.
If you need a certain amount of credits, the Scale and Enterprise plans have sub-tier levels that you can utilize to significantly increase your monthly credit limit.
Check our Plan Pricing ↗ page to learn more.
Note: Your monthly API credit resets independently from your billing cycle.
