You need an activated API key to use the API.
Step 1: Create your InstantData account
If you don't have an account already, register at https://instantdata.towerdata.com
If you already have an account, skip to step 3.
Step 2: Set up an API Key
After creating your account, select “Check out our API”.
You will be taken to the screen below.
Step 3: Creating an API key from the API tab.
If you have an existing InstantData account, click the "API" tab in the top navigation. You will also reach this page if you clicked "Check Out Our API" during the account creation process.
If you don't have an API key already, the "API" screen will look like this:
Click the green "Get Api Key" button at the bottom right to get your test API key or if you want to read up on the documentation, select the blue "Documentation" button on the bottom left.
If you click "Get Api Key", you will be given a test API key that includes 100 free queries for Email Validation and our most popular demographic fields.
You can have one key or several, depending on your needs, but your account representative will be the only one able to modify your chosen key to reflect your desired fields and/or services, appropriate limits in terms of volume, etc.
To request additional fields or API services, or to sign up for a paid account, contact us or speak with your account executive.
