Has anyone had experience with the Google Maps Geolocation API?

Question

Google

Guys, hello everyone. Tell me where did you use the Google Maps Geolocation API resource?
Tell me how you can find all these pieces of the client:
The main part of the request must be in JSON format. The following fields are supported, all of which are optional.

homeMobileCountryCode: The mobile phone country code (MCC) for the device's home network.
homeMobileNetworkCode: The mobile network code (MNC) for the device's home network.
radioType: mobile radio type. Supported values ​​are lte, gsm, cdma, and wcdma. Although this field is optional, it must be used (when present) for more accurate results.
carrier:the name of the communication service provider.
considerIp: Specifies whether to fall back to geolocation by IP address if no Wi-Fi hotspot or cell tower signals are detected. Note that the IP address in the request header may not be the device's IP address. The default is set to true. To disable this return, set considerIp to false.
cellTowers: An array of cell tower objects. See Cell Tower Objects below.
wifiAccessPoints: array of objects - Wi-Fi access points. See Wi-Fi hotspot objects below.
independent searches, unfortunately, so far have not led to anything
if you send without these things, then a very large error, about 9 km, for the city is a catastrophe
