You left some API keys in the code. I haven't tested if they work, but if they exist, it would be good to remove them.

by the way, good job!

@ricardochaves I knowingly left a few that were cycled out and only used for testing purposes so I wasn't worried... but given I don't make that clear in the documentation your concerns are justified so thanks for bringing that up!

As old an outdated as this doc is for my uses (i wrote this 4 and a half years ago and odds are a lot of it won't work right anymore, unsure) it's probably a good idea I update that just to be clear. Thanks!
