Is this is possible to fetch data through API that how much followers a snapchat user have?

Hello Stack overflow community,
I am trying to create an app where a user can put the link or username of his/her snapchat profile. And I want my app to automatically get the user's amount of followers he/she have and save it into a sheet. The reason for doing this is because then I want to assign advertising projects to him/her according to the followers he/she have. I want to fetch that data automatically through the API when a user enter his profile link or username.
And is it possible to check the amount of views a user get on any post by using link of that post through the API

Is it possible to get display name from google account email

Abstract
I develop a Google API integration for a Saas product.
One of its functions is to retrieve the email and displayName of the participants of an event registered in Google Calendar.(ref 1, same issue is reported)
At first I try to get email and display name from get method for google calendar events resources,but I found that many event participants have an email but no displayName.( ref 2,3 )
Then, I try to use google people api to get displayName from email but I couldn't find the way to get it.
Question
If you know the way to get displayName from google account email, please tell me how to do it.
Reference
Google Calendar API: Display Name doesn't work
Google Calendar API, Events Resource representations
Google Calendar API, Events Resource representations
The displayName availability depends either from that account's Name set at Google profile) or from the API caller's contact List in Google Contact.
If the caller and the affected account are within the same Google Workspace environment, then the domain's user profile Name is taken into account.
If that account is added to the caller's Contacts, then it is also possible to retrieve its Display Name via People API.
If the affected account doesn't have a name set nor it is within the caller's contacts, that's expected behavior.

twitter's user search api:- search using email id

I am working on a requirement where I need to fetch user profile from various social media sites. For example, I can use the twitter's user search api to fetch user profile using the user name. But i have only email address and want to fetch user profile data from twitter using email address. I found out that twitter's api does not support user search based on email address. Similarly facebook API also does not support user profile search based on email ID. Is there any other way to fetch the user profile data from these websites using email Id's?

Services that get facebook emails

I've noticed that my android phone, the iphone, outlook.com, and yahoo mail all can import my friends' email addresses (and sometimes phone numbers) from facebook. However, I don't see anywhere in the documentation of the API to suggest that you can get email.
Do these services have special agreements with Facebook or am I just not finding the specific api for "contact" importing? I've not had any luck using "email" field with friends api.
Any ideas?
These services have some special agreements with Facebook and thus are able to retrieve the Email Ids of the Friends of the User. Most of them don't allow further exporting of data obtained from there directly.
And as per Email Permissions documentation here it clearly states that for App Developers
Note: There is no way for apps to obtain email addresses for a user's friends.
As per the phone number, there is no access to it no matter what permission. You may though ask the user to fill those for you.

Send an Email as the Currently Logged in User | Google API

Is it possible to send an email to join the site as the currently logged in user on your site to his/her contacts?
You can do that now with the GMail API. You will need the user's consent of course, and will need the Contacts API to retrieve the user's contacts.
