  1. Exchange Broker

Introduction

Exchange Broker Program (Crypto-as-a-Service)#

The Exchange Broker Program (Crypto-as-a-Service) offers a flexible brokerage service designed for managing client accounts without disclosing their identities to KuCoin. As an Exchange Broker, you handle all aspects of client management, including customer registration, funding, customer service, and marketing.

Key Features#

The program provides a robust set of API services to streamline operations, including:
Creating unlimited sub-accounts
Deleting sub-accounts
Generating API keys for sub-accounts
Querying sub-account rebate records
And more
Sub-account API keys enable trading functionalities such as placing orders, viewing account assets, and managing deposits. Note that withdrawals and KCS deductions are not supported for sub-accounts and must be handled through the broker's Special Account.

Broker Special Account#

The broker's Special Account (Sub-account) functions similarly to a "main account" in a standard KuCoin account. Most endpoints available to a main account in the ordinary API interface are accessible for the broker's Special Account, except for KCS deduction functionalities.

API Key Clarification#

To ensure correct API access, please distinguish the following API key types and use the appropriate key for each endpoint group:
Management API Key (ND Broker API Key): Used for sub-account management and broker-related APIs, such as creating or deleting sub-accounts, querying rebate records, and the APIs highlighted in the yellow rectangle in the screenshot.
Trading API Key: Used for trading-related endpoints, including placing orders, querying account assets, and managing deposits.
Futures Lead Trading Key: Used for the futures lead trading APIs highlighted in the orange rectangle in the screenshot.
Screenshot 2026-03-13 at 15.31.35.png
Usage by Endpoint Group
1.
For the API marked with a red rectangle in the screenshot, please use the API Trading Key.
Note: To access the trading permissions of a specific sub-account, the broker must create and manage a separate trading API key exclusively for that sub-account. Please use Add sub-account API and Get sub-account API for this purpose.
2.
For the APIs highlighted in the yellow rectangle in the screenshot, use Management API Key.
3.
For the APIs highlighted in the orange rectangle in the screenshot, use Futures Lead Trading Key.
Please locate your Management API Key, API Trading Key, and Futures Lead Trading Key on the official page shown in the screenshot.

Ideal Clients#

The Exchange Broker Program is tailored for a variety of clients, including:
Cryptocurrency exchanges
Wallet providers
Cryptocurrency payment service providers
Custodial or non-custodial trading platforms
Aggregation trading platforms
By leveraging the Exchange Broker Program, you can efficiently manage client accounts while maintaining full control over their trading experience.
