Authentication

For all endpoints, you must provide KuCoin API credentials with Broker-level permissions.

Required credentials:

• API Key (KC-API-KEY): Your KuCoin Broker API key
• API Secret: Your KuCoin API secret (used for signing)
• Passphrase (KC-API-PASSPHRASE): Your API passphrase (HMAC-SHA256 encrypted)

Base URL:

• Production: https://api.kucoin.com

Security

Share Credentials

Users can provide KuCoin API credentials by sending a file where the content is in the following format:

your-api-key
your-api-secret
your-passphrase

Never Disclose API Key and Secret

Never disclose the location of the API key, secret, or passphrase file.

Never send the API key, secret, or passphrase to any website other than the official KuCoin API endpoint.

Never Display Full Secrets

When showing credentials to users:

• API Key: Show first 5 + last 4 characters: abcde...wxyz
• Secret Key: Always mask, show only last 5: ***...s3cr3
• Passphrase: Always mask entirely: ***...

Example response when asked for credentials: Account: main API Key: abcde...wxyz Secret: ***...s3cr3 Passphrase: ***...

Listing Accounts

When listing accounts, show names and environment only -- never keys: KuCoin Accounts:

• main (Production)
• broker-keys (Production)

Transactions in Production

When performing operations that modify data (transfers, creating sub-accounts, updating API keys), always confirm with the user before proceeding by asking them to write "CONFIRM" to proceed.
