I need a widget for our real estate agency website that displays a preview of a home's value using RentCast's API. The widget should work by showing a preview of the full report, which includes a full competitive market analysis, and then hide the complete details behind a lead capture form. This ensures visitors provide contact information to access the detailed data. The widget needs to deliver a user-friendly experience with accurate integration of the RentCast API. Please ensure the design is clean and the functionality is seamless for potential leads.
