Developer question: service call for Location

Greetings.

I have built an AI model for minor image processing, facial recognition, and identification card reading. It works within all parameters and I am happy with result.

I have wrote a complete age verification module that looks very professional, and uses web cam / phone cam for real time pictures. I am considering releasing this module, but it would be on a subscription base since I would have to charge per verification. With the computing requirements I could essentially provide verification for 1000 scans for $20.00 (0.02 ea) - where most providers for such are wanting .50 to .90 per scan. I need to know interest in this, and I will decide whether I want to design an API.

Now... To my question... From scanned identifications, I have a complete address. I would like to filter this through the UNA location service to get long and lat. Also to update bx_persons data table. I don't want to hardcode a provider, since it can switch in UNA.

Can you please provide me with a sample call to the internal UNA location functions? Or please give me the files I need to look through for the code necessary?

Thank you!
