Since we have radio inbuilt in the device there must be some API available for scanning the stations

I would venture that less than 1% of Android devices have any sort of "radio" that has "stations". If you happen to have a device that has an AM, FM, shortwave, or similar sort of "radio", you are welcome to contact the manufacturer of that device to see if they have some sort of means to allow you to control it.
