| Variable         | Required | Description                                                                             |
| ---------------- | -------- | --------------------------------------------------------------------------------------- |
| `COHERE_API_KEY` | Yes      | Cohere API key from the Cohere dashboard [Docs](https://dashboard.cohere.com/api-keys). |

## Setup

1. **Create a Cohere account**: Go to [https://dashboard.cohere.com](https://dashboard.cohere.com) and sign up or sign in. New accounts get a free trial key that works for evaluation without billing.
2. **Create an API key**: Open [https://dashboard.cohere.com/api-keys](https://dashboard.cohere.com/api-keys). Use the trial key for testing, or click 'New Production Key' for production use (requires billing details).
3. **Store the key**: Copy the key and add it to your .env file as COHERE\_API\_KEY=...
4. **Verify access**: Run the List Models tool to confirm the key works. A 401 means the key is wrong or revoked.

* Trial keys are free but heavily rate limited - switch to a production key for real workloads
* Chat, Embed, and Rerank calls are billed per token/search unit on production keys
