How do I authenticate Genius API on Retool

I want to use the Genius API on my Retool frontend. However I am rather new to using APIs and lack the knowledge on how to do the authorizations for APIs in general.
My questions are below:
Which type of authorization does Genius use, can you tell given the below screenshots of the APIs details? I asume OAuth 2.0
On the retool Resources setting form, under OAuth2.0 they ask for a couple of properties under Authenication, where do I get these:
Authorization URL
Access Token URL

Instagram API - Fetching list of followers for my account

I am making a widget for my iPhone to fetch data about my Instagram followers. I won't be putting it on the App Store, and I won't be fetching any other users' data.
Can I do this? I have tried to figure out what to do but I think I have to register my website, even though I'm not making a website and this won't be shared with anyone else.
As stated in Instagram Developer Documentation, you will have to register your application before using the API.
1. Register
We'll assign an OAuth client_id and client_secret for each of your
applications.
2. Authenticate
Ask users to authenticate and authorize your application with
Instagram.
3. Start making requests!
Make requests to our API Endpoints with the users' OAuth credentials.
The takeaway here is that you'll need the OAuth credentials to access the API.

Can you authenticate the Twitter API within the URL?

Is it possible to authenticate the Twitter API through a URL in a web browser?
ex. https://api.twitter.com/1.1/search/tweets.json?q=%40twitterapi&secret_token=234234234234
I've been researching this for quite a while and haven't found a definite answer.
And if so, where in the docs would the names of the variables be that I need to authenticate via a URL?
No, that's not how the Twitter API works. You need to construct a valid OAuth authorization string and include it as the header in your request.
See Authorizing a Request in the Twitter REST API documentation.

How to use OAuth2.0 token with Google Translate

According to the Google Translate API docs, https://cloud.google.com/translate/v2/using_rest, you can authenticate with OAuth 2.0 or an API key.
All of the examples online I've seen simply provide an API key.
Do you know how to run a Google Translate API call with an OAuth 2.0 access token?

Server-to-server calls with YouTube API

I need to access the YouTube API, authenticating as a single account so I can access its videos, tags, comments, etc.
A Public API Access key does not seem to cover this scenario as tags aren't visible to the public. Is it necessary to implement OAuth just to authenticate one account? I have no intention of having other users authenticate with the web app - only the YouTube account that belongs to the owner of the web app.
I have the username & password for the YouTube account. Is there no way to authenticate one YouTube account with the API as a single-user?
A Service Account seems most suitable for me, but apparently the v3 API doesn't support them.
