The API uses a universal credit system where API credits can be used across endpoints. For more details on how credits are used and the cost associated with various endpoints, visit the Key Concepts section in our Developer Platform’s API Documentation here.
Contact credits give you access to the contact information we have available for a professional, which may include an email address, a phone number, or both.
API and Contact credits can be bought via the Credits section in Subscription Management, by clicking Add Credits.
Credit pricing are based on subscription level and can be found here.
Please note that once purchased, credits never expire.
