react-native-maps which api use and how is its costs?

I'm creating an app based on maps.
From 11 June 2018 Google changes his price plan of the Google Maps Api.
I read here (Google maps price matrix) that for mobile application it's unilimited free.
But... which api use Google Maps in this library?
I try to use the library and for emulator not use Google API KEY. In this way i'm not sure that i use only free plan.
How i understand how calculate my costs? If there are.
I found all information about it.
react-native-maps use Maps SDK for iOS and Android.
This page Google Maps Costs examplain that for SDK there aren't costs.
I tried to enable only SDK Api and check report monitor on Google Cloud console
In this way you can use dynamic maps, use marker in your react application without costs.
It is different if you use search api or geocode api. This api follow the common cost of api reported in previous link.
In this case you can use mix of Google Maps SDK and Open Street maps API

Must I use Google play billing library if i want to sell an ad space directly to advertisers?

I want to sell an ad space in my Android app that's on play store. I want to sell it directly to advertisers who will need to pick the target for their ads, Is it a must to use google play billing library to get payed for the adspace or i will be violating google play terms if i use another payment system. I went through this article https://play.google.com/about/monetization-ads/payments/ unfortunately it was not clear to me. Any help please.
No, Google Play Billing Library only supports selling digital goods and click-based ads.

Google analytics demo account

I am keen on learning more about Google Analytics but the accounts I have access to only have 70% of the functionalities implemented.
Is there a google demo/test account (free service) that I could use to explore all GA Features?
Thanks in advance for any feedback!
There isn't any official Analytics demo account.
But Google Analytics is free, so create an account and play with it or/and learn with the tutorials !

API/method to create a sub-account in Google Merchant Center

I have a multi-client account for Google Merchant Center ("GMC"). To submit products to GMC, I need to create several thousand sub-accounts (one for each user of the site I'm submitting). Doing this manually is not an option. I can't find any API or way to do this. Do you know of a way?
you can use the new Google Content API for Shopping v2 to achieve this.
