Why I did this?

I initially wanted to combine the subscriber numbers of Feedly and Inoreader — two of the most popular RSS providers, to calculate how many people are subscribed to my blog's RSS. Then it occured to me: I could actually make this into a "Hub", where you can provide a service name, a query key, and out comes the total subscribers of all your services...Hence, I proudly introduce: Substats!

PROs

• 🧊 Serverless deployment, minimum overhead (powered by Cloudflare)
• 🚀 Ultra-fast reachablility for all services (even in mainland China!)
• 🎈 Simple integration, easy-to-use API with nice badges provided by Shields.io

API endpoint

🚦 Only 'GET' requests are handled in order to integrate with badges.

https://api.spencerwoo.com/substats/

Single query

You can make a single query to request your RSS subscribers on Feedly.

GET /?source=feedly&queryKey=https://blog.spencerwoo.com/posts/index.xml

Which returns:

{ "status": 200, "data": { "totalSubs": 13, "subsInEachSource": { "feedly": 13 }, "failedSources": {} } }

You can then use the numbers in data.totalSubs in a dynamic badge:

Multiple sources with a single query string

GET /?source=feedly|inoreader|newsblur&queryKey=https://blog.spencerwoo.com/posts/index.xml

Which returns:

{
  "status": 200,
  "data": {
    "totalSubs": 49,
    "subsInEachSource": {
      "feedly": 17,
      "inoreader": 29,
      "newsblur": 3
    },
    "failedSources": {}
  }
}

Enter the badge! (NewsBlur is too slow to load, below is a static badge for demo purposes.)

Multiple queries

GET /?source=telegram&queryKey=realSpencerWoo&source=sspai&queryKey=spencerwoo&source=twitter&queryKey=realSpencerWoo

Which returns:

{
  "status": 200,
  "data": {
    "totalSubs": 1552,
    "subsInEachSource": {
      "telegram": 786,
      "sspai": 638,
      "twitter": 128
    },
    "failedSources": {}
  }
}

And of course, our badges!
