|---|---|---|
CohereApiError: invalid api token | Wrong or expired key | Regenerate at dashboard.cohere.com |

The SDK reads CO_API_KEY automatically if set. You can skip the token param:
// Auto-reads CO_API_KEY from environment
const cohere = new CohereClientV2();
After successful auth, proceed to cohere-hello-world for your first real API call.
