Is there a product that can get body temperature of a person and allow me to get that value using an API or any other integration in real time?

I am expecting input device to be a smartphone. Maybe some external sensor can be used to get real time temperature but I am looking for a complete product that I can use/purchase.

The temperature I am looking to get is from a human. So the device has to have the ability to acquire that value and send it to a cloud service. That cloud service has to be able to provide me that temperature value.

Please advice.
