Check available appointment slots for a specific service at a local business on a given date. This calls the business's configured availability provider live and fails closed when the provider fails. Returns time windows when the business is free and the service bookingStartPolicy permits the start. For services with maxParticipants > 1, provider-returned starts remain available until capacity is full. ONLY call this if the business has 'booking' in its enabledFeatures array. If the business doesn't support booking, share their contact info from get_business_info instead.
