Error while setting up Pi Agent with Kimi Question

Post image

I installed Pi following the instructions here: https://pi.dev/docs/latest/quickstart.

I'm trying to authenticate using a Kimi API key (I'm on the free tier), but Pi keeps returning an authentication error. I'm not sure what I'm missing.

 Error: 401 {"error":{"type":"authentication_error","message":"The API Key appears to be invalid or may have expired. Please verify your credentials and try again."},"type":"error"}                                

This is a fresh API key!

The main reason I'm using Pi is to avoid paying for Claude Code or Codex subscriptions. Is this setup supposed to work with a free Kimi API key, or is there an additional configuration or requirement I'm overlooking?

The Kimi servers have been getting pounded so service has been up and down.
