I've used avatars.io for many projects - most recently https://wayback.4ty2.fun.
It's a super simple image API, and I can build cool live previews of profiles with it too π
I use it for one of my project, but recently, Avast consider avatars.io to be a malicious link and throw tons of warning message to my visitor's browser π

Support for more avatar services like https://avatar.tobi.sh and http://avatars.adorable.io would be super cool π₯
Pros:Super simple API, works with multiple socials
Cons:The client libraries don't work, Github is down
