The KellPro API was created to give customers with development resources a way to quickly and easily access information they need. The API itself is RESTful and requires a valid access key.

If you have any questions about the API or how to implement it into your systems, you may contact us at any time.

Pricing & Payment Options

$200 monthly fee

$5 every 1,000 transactions

Currently, you'll need to sign up for an account and sign up for the API subscription there. We accept most major credit card providers. You will be able to create and manage your API keys through the interface.

How to Calculate Transactions

We calculate usage based on what we call transactions. A transaction is counted as the request, plus each record returned in the results. For example, a search that returns 3 records would count for a total of 4 transactions. Requests that return errors do not count toward your transactions.

The charge for a group of transactions is only counted every time 1,000 transactions is reached. At that point, the charge will be added to your current month's invoice.

Client Libraries

A simple client library written in PHP. This is what we use to access our own API here at KellPro.
