Abstract: Cameras capture images of shelves/displays having items. The images are processed to identify real-time item counts on the shelves and/or empty or partially empty shelves with less than a configured number of items. Notifications or messages regarding item counts and/or empty shelving conditions are sent through an Application Programming Interface (API) to consuming services in accordance with custom defined rules. In an embodiment, real-time item counts and/or empty shelving conditions are dynamically reported through the API based on on-demand requests from the consuming services.
