Leaking an API access token to the web client... oh no no noooo...

are those the api keys that get used in npm packets for everyone to use for free

including your api key in a stackoverflow question

Leaking api keys on github

Use your api key as an example in the documentation ( ͡° ͜ʖ ͡°)

I for one appreciate when apps do this. It makes it so much easier to figure out how to use their stupid API in the first place rather than navigating through a bunch of crappy docs to access endpoints that don't do what you need.
