I was looking to see what the actual metrics would be for a completion, to see if this is something of interest to me. So I tried to run the example here:

https://www.traceloop.com/openllmetry

Problem 1 (very minor): it's missing an `import os`

Problem 2: I need an API key.

Problem 3: The link that it tells me to go to for an API key is malformed: https://https//app.traceloop.com/settings/api-keys

Is there a way to see what the output is like without getting an account, and presumably also connecting to an observability platform like Grafana? I already made a venv and installed the package, so I'm not sure if I'm ready for even more steps just to see if this is something that might be useful to me.
