For our first project, we developed a prototype Eligibility API for The Special Supplemental Nutrition Program for Women, Infants, and Children (WIC). This work allowed us to show that we could accommodate varied state policy options into a single Eligibility API ruleset. (Note: The prototype is for demonstration purposes only and is not an official interpretation of policy.)

For our second project, we developed an Eligibility API for Disaster Supplemental Nutrition Assistance Program (D-SNAP) as well as an online Regististration App that uses the API.
