What is TowerData's API?

TowerData's API allows you to process data in real time.

TowerData’s API allows you to quickly and securely verify email addresses and match demographics and behavioral data to your customer list in real-time. TowerData has APIs for Email Validation, Email Intelligence and Identity Matching, and your API keys can be managed through InstantData.

You can use the API to process one record at a time in real-time or use our List API to submit files of up to 1,000,000 records at once.

TowerData’s API dashboard on InstantData includes a client’s API key and summary charts, as well as download links for detailed reporting by day and month, fill rates and validation reports. Any files submitted through the List API will be visible on the List Summary section of the dashboard.


You don’t have to be a programmer to use the API! You can upload files to run against on of your API keys via the InstantData dashboard.

Clients can test the API with up to 100 queries per month.
