Scout is an automated system providing constant end to end testing and monitoring of live APIs over different environments and resources. Scout does it by periodically running self explanatory Python tests. https://blog.cloudflare.com/keeping-cloudflare-api-all-green-using-python-based-testing/

At Cloudflare, we reuse existing core systems to power multiple products and testing of these core systems is essential. In particular, we require being able to have a wide and thorough visibility of our live APIs’ behaviors. We want to be able to detect regressions, prevent incidents and maintain healthy APIs. That is why we built Scout. blog.cloudflare.com/keeping-cloudflare-api-all-green-using-python-based-testing/
