If it doesn't connect

  • BoltAI couldn't verify this API key: copy the key again in full. If you just created it, wait a few minutes and try again.
  • Setup works, but replies fail: the account may be out of credits. Check your billing in your Anthropic account.
  • A model is missing: on the provider's page, click Refresh Model List.
  • On the provider's page, open the ⋯ menu and choose Test Connection.
