You'll be prompted at install for:
| Field | Required | Notes |
|---|---|---|
api_key | yes | Your public API key from https://dashboard.coinvoyage.io → Developers |
api_secret | optional | Needed for SALE/REFUND orders, webhook management, and fee claims. Leave blank to restrict Claude to read + DEPOSIT flows only. |
api_base_url | optional | Defaults to https://api.coinvoyage.io |
