Introduction
Welcome to KuCoin’s trader and developer documentation. These documents outline the exchange functionality, market details, and APIs.Key Upgrades#
Compared with the old version of the API documentation, the main changes are as follows:Online Debugging Supported
Each REST interface can be directly tested and run online—what you see is what you get. (The current version only supports the Public endpoint. We will support all interfaces in the next version.)
SDK Refactoring
We have rewritten the SDK in all languages, with more standardized data specifications and a more convenient user experience. Offline Data Download Supported
Market data obtainable through Offline Data Download function to facilitate backtesting. Readability Improvements to API Documentation
The API documentation has been revised and proofread to improve clarity and reduce confusion. Any parts of the previous documentation that were not clear have been revised to provide better explanations.
Document Structure#
Under each endpoint, there are several modules, as follows:1. domain#
Prefix domain name. The request URL needs to be determined by BASE and the specific endpoint combination.2. api-channel#
Private or Public endpoint. If it is a private interface, apikey is required to access it.3. api-permission#
You can manage the API permission on KuCoin’s official website. Please refer to the documentation below to see what API key permissions are required for a specific route. The permissions are:General: Limited to read-only operations such as querying account information, account statements, and order information. The API cannot be used to perform operations such as order placement or withdrawals.
Spot: This API can be used for spot trading to perform order placements, order cancellations, etc.
Margin: This API can be used for margin trading to perform order placements, order cancellations, etc.
Futures: This API can be used for futures trading to perform order placements, order cancellations, etc.
Earn: You may use this API to subscribe to, redeem, or make early redemptions of KuCoin Earn products.
Withdrawal: This permission allows you to withdraw assets, acquire deposit addresses, cancel withdrawals, and execute other operations. To use this permission, you must enable IP Restriction. Please note that when authorizing the Transfer permission, you can use the API to transfer money without email verification or Google verification.
FlexTransfers: Allow this API key for FlexTransfers. This will enable asset transfers across the multiple supported transfer types. The respective permissions for each individual transfer type remains unaffected. If this option is enabled, IP access restriction filters must also be applied.
LeadtradeFutures: Allow this apikey to use the Futures CopyTrading function. Please note that only the TRADER (Lead Trader) need use this permission, not the FOLLOWER (Copy Trader).
