StatusAPI tracks popular APIs (AWS, Githbub, Stripe, etc) and provides realtime data on any outages. Think of a status page (ex. https://status.io/ ) but 100% automated, granular APIs monitoring, and collected by a trusted 3rdParty.
Check it out, let me know what you think. We are looking to provide a subscription model to realtime + historical data, please let me know if you would be intersted. Thanks folks!
