Environment Variables
| Variable | Required | Description |
|---|---|---|
KUCOIN_API_KEY |
for authenticated use | KuCoin API key. |
KUCOIN_API_SECRET |
for authenticated use | KuCoin API secret. |
KUCOIN_API_PASSPHRASE |
for authenticated use | KuCoin API passphrase, set when the key was created. |
All three fall back to a constructor argument of the same name
(KuCoin.new(api_key=..., api_secret=..., api_passphrase=...)), and all three are
skipped entirely for a KuCoin.new(public=True) client. None are read from anywhere but
the environment or the constructor call — keep them in an untracked .env file or your
process's own secret store.
