I am currently making a site to promote esport professional streams and I am trying to figure out how to check if a channel is live and display it next to the hyperlink for the stream, this is the site currently and I will be needing to add that “check” for ~200-300 streams for the LoL tab [http://www.prostreams.gg/](http://www.prostreams.gg/) Any advice on has to how I should do this?

Use the following API endpoint (at least in v5):

> **[Reference](https://dev.twitch.tv/docs/api/reference/)**
>
> Twitch Developer tools and services to integrate Twitch into your development or create interactive experience on twitch.tv.

You can query 100 channels at a time, so break your list up accordingly. Remember that it is 2-3 minutes behind when streams actually go live as it is cached data. Do not constantly poll the endpoint though, put a pause between each query.

If wanting to use the New Twitch API:

> **[Reference](https://dev.twitch.tv/docs/api/reference/#get-streams)**
>
> Twitch Developer tools and services to integrate Twitch into your development or create interactive experience on twitch.tv.

Again, limited to 100 channels at a time. Rate limits are enforced here so be sure that you are following the rate limit guidelines depending upon the type of authentication you are using.

100 channels per page or could I set it to do 100 more channels after that?

You can scan 100 at a time. You would just need to break your master list of channels, be it 100, 200, 350, 512, … channels into lists of 100 and then perform a query for each list. Build up a master list of the data that comes back and refresh your page from that. You could even refresh in between queries if you wanted. However you are designing your solution.

Think of the code like this (quick and dirty):

```auto
ChannelIndex = 0
FOR ListOfChannels
    FOR 1...100
        QueryListOfChannels += ListOfChannels[ChannelIndex++]
    DONE
    responseData = QueryTwitch(QueryListOfChannels)
    UpdateWebPage(responseData)
    DELETE QueryListOfChannels
DONE

```

There are probably better ways to accomplish this, this is just off the top of my head.

I appreciate the help, I have no experience in web dev outside of what I have learned this week making the site, so all of this really helps!
