Using web scraping to recive all Twitter followers

I want to create giveaways which require the participants to follow the twitter account of the giveaway creator.
My first idea was to use the Twitter API (endpoint: "/2/users/:id/followers"). This works fine for me however I always run into rating limits. The API allows me to send 15 requests every 15 minutes and returns a maximum of 1000 users per request. Since many accounts have more then 15000 followers and since many request happen at the same time (many users want to participate in a giveaway) this solution is not suitable for me.
My secound idea was to use web scraping instead (e.g Node Fetch). I was following along this tutoria: However doing so I always run into the issue that Twitter uses random strings to name their html elements. You can see in the picture there is no defined class to grap the elements.
So my main question is how can I access these element ?
Random Follower of my Twitter Account
I also have a follow up question regarding the effictivness of this method. Assuming I have multiple people who want to particpate in a short amount of time (e.g 10 people in 5 minutes) and they all need to follow a big twitter account (e.g 100k followers).
Is it efficent to scrape all 100k followers each time or should I instead try to fetch the 100k followers once, safe them to my database and use my database to check for each user later ?
As a side note, I am using node.js and node-fetch, however I have no problems to switch the framework. In addition I think the grabbing of the element as well as the performance should be universal.
Thanks for your help :)
They're going to detect your servers excessive calls. There is a Twitter Developer Portal where you can request elevated access which may raise the limits for you.

What's the rate limit between requests for Instagram's Private API?

I want to get the whole list of followers, which means iterating through the pages. However, I don't know whether instagram will ban me with too many requests too quickly. Does anyone know the rate restrictions on instagram?
Instagram's private API works like the app do, so you won't have the limits that the official API has, however, you still can't make as many requests, in that case Instagram will know and ban your account.

Set API MaxTimeout in Loopback.io and detect slow apis

We are using loopback.io for writing and exposing our apis.
I need to do two things on my apis -
Need to set max timeout say 30 sec. max, for all apis. ( I tried some ways from Internet, none of them worked. )
If I am able to set the timeout for apis, I Need to get Slow apis list like alert, email or slack notification whatever possible.
All APIs which are not able to give response withing 29 seconds, I will send the api name as an slack notification that the API is taking time.
Any workaround on this?
Thanks,

Is there a way to get Instagram #Mention History via API or otherwise?

The native application doesn't show all the activity, only the most recent.
Therefore I lose 70-90% of my notifications overnight. There must be a way to get all that historical data.
I told you can't, but, thinking.. you can. :)
The API don't provide that facility.. You can check all endpoints here: http://instagram.com/developer/endpoints/
But you can iterate over all your medias an get all comments and likes. If you store it locally, after, will be possible to request API again and check your new unseen interactions.
It will work for likes and comments.

How to grab instagram users based on a hashtag?

is there a way to grab instagram users based on a specific hashtag ?
I run contests based on re posting photos with specified hashtag then randomly pick a winner, i need a tool that can grab the usernames of those who reposted that photo and used that hashtag.
You can query instagram using the API. There are official clients for both python and ruby.
You didn't specify what language/platform you are using, so I'll give you the generic approach.
Query instagram using the Tag Recent Media endpoint.
In the response, you will receive a user object that has the user's username, id, profile url, and so on. This should be enough to do what you are describing.
As far as tools, there aren't great options to probably do things exactly how you want. If you just want a simple contest, you could use statigram, but it's not free.
If you roll your own solution, I highly recommend you also do the following:
Implement a rate limiting mechanism such as a task queue so you don't exceed your API calls (5000 per hour for most calls). Also useful for failures/network hicups, etc.
Have users authenticate so you can use OAuth to extend your API calls to 5000/per user/hour to get around #1.
Try the subscribe API if there won't be many items. You can subscribe to a specific tag as well, and you will get a change notification. At that point though you need to retrieve the actual media item(s), and this can cost a lot of API calls depending on how frequent and what volume these changes occur.
If your users don't have much photos/relatively small/known in advance, you can actually query the user's recent media instead and filter in your own code by hash tag.
