API Setup
You can use the Web API for free (up to 100,000 a year)! You will need a User ID. Once you get a User ID then you can API Codes for embedding in your Web api calls. We use the API Codes to keep track of your usage. The first 100,000 api calculations in a 12 month period are free. 100,000 is all probably all you need, but if you get near that limit you can purchase additional 100,000 calculations for a fee of $99.00.
