API and Workbench usage is billed via prepaid “usage credits”. Credits must be purchased prior to using the API, and your credits will be applied to your usage according to our current pricing. Failed requests are not charged, and you will only be billed for successful API calls and completed tasks.

You can track credit usage in the Billing page. If you run out of credits, you will no longer be able to call the API or use Workbench. You can choose to set up an auto-reload that purchases additional credits when your balance falls below a set limit.

To add usage credits and adjust your auto-reload settings, navigate to your Billing page. Click on the “add funds” button, and enter in the amount of credits you would like to purchase. After you’ve purchased your credits, they will be immediately available to you.

To adjust your auto-reload options, click on “edit settings”. You can toggle auto-reload on or off. If choosing to use auto-reload, you can set the minimum account balance, and the amount to reload to if your account reaches that minimum balance.

Please note that purchased credits are subject to our Credit Terms.
