The Address Matching System Application Program Interface (AMS API) Developer's Kit is a tool used in the development of address-matching software. It is available on CD-ROM media commonly referred to as the AMS Commercial CD-ROM and contains the following information:

• API library(s) for each specific computer platform
• Interface definition file (ZIP4.H)
• Test utility (SAMPLE.EXE)
• Test utility source code
• Sample configuration data files
• User documentation

The test utility can be used to ensure that the Address Matching System and data files have been installed correctly and to provide access to USPS® matching logic, which displays the standardized address returned by the matching engine. This enables you to verify the accuracy of the ZIP + 4® results returned from your product.

The AMS software, including, but not limited to, .DLLs, shared objects and static objects all expire and cease functionality based on the CASS™ guidelines. The eLOT® and DPV® files can also be used in conjunction with the AMS API Developer's Kit.

Subscriptions are maintained on a calendar year basis and require signature compliance with a license agreement. Pricing varies depending on product and platform usage, so please ask for more details.
