On our pay-as-you-go plan, you can choose to set a usage limit for your account.
You can limit your daily usage up to 50,000 lookups per day. When the daily maximum is hit, you will not be able to process spreadsheets or use the API. The daily counter is reset at midnight EST.
If you've purchased credits, you can also limit your account to the free tier once your credits run out.
API requests will return 403 Forbidden when the limit threshold is met. Please ensure that your API integration handles this error gracefully.
