Massive needs an API key. If the user doesn't have one (or you get a 401),
give them the signup link to register themselves:
https://massive.com/dashboard/signup

Their key is at https://massive.com/dashboard/keys. Have the user put it in the
MASSIVE_API_KEY env var and read it from there; don't ask them to paste
the key into chat or hardcode it.
