Daily Limits & API Key Management

Each active API key receives the daily request limit associated with its plan. Usage is tracked by the API middleware. When the daily limit is reached, additional requests are blocked until the usage period resets. Customers can also disable their own API keys from the account area.

Data Quality & Responsible API Use

Business information can change over time. API access does not make business contact information permanently accurate or guarantee email deliverability.
