Here is the reply from the USPS. Was I asking for the wrong thing? Would someone from Web Assist please assist me here. What exactly am I asking the USPS for so that this will work? Exact wording or link would be appreciated. My store is not working due to this problem.
Dear USPS Customer,
Address Information APIs are accessible with special permission. The APIs can only be used in conjunction with USPS SHIPPING SERVICES ONLY.
We must first understand how you'll be using the API. We need a commitment that the API will be used on a transactional basis (not batch processing or cleansing of a database, but as a customer enters the information into a form on a website). Also, you must state that you will use the output from this API solely in association with USPS SHIPPING SERVICES ONLY.
Please provide a detailed description how you plan to use the APIs, include the URL of the site (development or production). We will review the material received to see if you meet our requirements.
If your implementation does not meet these requirements, I suggest contacting the NCSC for other Postal products that may meet your needs.
The Address Management System Application Programming Interface (AMS API) is available on a subscription basis for $3,800/year with bi-monthly updates. For more information, write to:
