Quick Start

Introduction

The KuCoin Pool Developer Documentation is an API document written for users who wish to obtain data from the KuCoin Pool.

Upcoming Changes

08/05/2023:

  • Update Interface /v1/external/earn/query,/v1/external/worker/query,/v1/external/worker/get,/v1/external/earn/query,/v1/external/reward/query add coinName field to request parameter

23/02/2023:

  • Update Interface /v1/external/earn/query adds rejectRate field

14/07/2022:

  • Add Accumulated income of user interface

27/07/2022:

  • Add Accumulated income of all sub-accounts interface

07/09/2022:

  • Update The maximum value of paging parameter pageSize is 100
  • Update The request parameter sortField of the interface /v1/external/worker/query cancels the HASH_RATE_DAY sorting

REST API

API Server

Base URL: https://www.kucoin.com/_api/miningpool

The request URL needs to be determined by BASE and specific endpoint combination.

Endpoint of the Interface

Each interface has its own endpoint, described by field HTTP REQUEST in the docs.

For the GET METHOD API, the endpoint needs to contain the query parameters string.

For example, to obtain mining income data, the default endpoint is /v1/external/earn/query. If your request parameter is algo=SHA256d, then the endpoint will be /v1/external/earn/query?algo=SHA256d. Therefore your ultimate request URL should be https://www.kucoin.com/_api/miningpool/v1/external/earn/query?algo=SHA256d.

Request

  • The POST request should be application/json.
  • The return type of requests is application/json.

All timestamp parameters are calculated in Unix timestamp milliseconds unless otherwise stated (e.g., 1544657947759).

Request Parameter

For GET requests, the parameters should be spliced into the request URL (e.g., /v1/external/earn/query?algo=SHA256d).

For POST and PUT requests, the parameters should be spliced into the request body in JSON format (e.g., {"algo": "SHA256d"}). Note: Do not add spaces to the JSON string.

Returned Error

The system will return an HTTP error code or a system error code. You can troubleshoot the cause of the error based on the returned parameter messages.

HTTP Error Code

Code Description
400 Bad Request -- Invalid request format.
401 Unauthorized -- Invalid Api-Key.
403 Forbidden or Too Many Requests -- Requests are forbidden or have exceeded the request frequency limit.
404 Not Found -- The specified resource could not be found.
405 Method Not Allowed -- The method you requested the resource from is invalid.
415 Content-Type: application/json -- The request type must be application/json.
500 Internal Server Error -- Server error, please try again later.
503 Service Unavailable -- The server is under maintenance, please try again later.

ystem Error Code

Code Description
200002 Please try again later -- Requests have been sent too frequently. The interface has begun limiting requests.
400001 Any of key, timestamp, passphrase, version is missing in your request parameters -- Missing parameters for signature verification in the request parameters.
400002 Invalid timestamp -- The time difference between the request and the server is more than 5 seconds.
400003 Key not exists -- The API-Key does not exist.
400004 Invalid passphrase -- The passphrase is incorrect.
400100 Parameter Error -- The request parameter is invalid.
500000 Internal Server Error -- Server error, please try again later.

If the system returns an HTTP status code of 200 but the service fails, the system will report an error. You can troubleshoot errors based on the returned parameter messages.。

API Return

The API return is in JSON format.

When the system returns HTTP status code 200 and system code 200000, this means the response was successful. The return results are as follows.

  1. General Requests
{
  "success": true,
  "code": "200", //status code
  "msg": "success", //error message
  "retry": false,
  "data": "" //returned data (any type, representing the returned data)
}
  1. Pagination Requests
{
  "code": "200", //status code
  "data": {      //returned data (any type, representing the returned data)
    "currentPage": 1, //current page
    "items": [], //array data
    "pageSize": 10, //results of each page
    "totalNum": 100, //total results
    "totalPage": 10 //total pages
  },
  "msg": "success", //error message
  "retry": false,
  "success": true
}

Pagination

Pagination allows the fetching of results using the current page count and is highly suitable for fetching real-time data. For example, the /v1/external/worker/query and /v1/external/earn/query endpoints both return the results of the first page by default, with a total of 50 pieces of data. For more data, specify additional pagination based on the currently returned data and then make the request.

Request Parameters

Parameter Default Value Description
currentPage 1 Current page
pageSize 50 Number of results per page (min: 10, max: 100)

Example GET /v1/external/worker/query?currentPage=1&pageSize=50

API Verification

Create Api-Key

Before making a request through the API, you must create an Api Key from the official website from KuCoin Pool > Settings > API Management. After creating an API Key, store the following three pieces of information in a safe place.

  • Api-Key
  • Api-Secret
  • Api-Passphrase

The Api-Key and Api-Secret are randomly generated and provided by KuCoin, while Api-Passphrase is defined by you when creating the API. If the above information is lost, it cannot be recovered and you will need to re-apply for an Api-Key.

Creation Request

The REST request parameters must contain the following:

  • key: Api-Key(passed as a string)
  • timestamp: the timestamp of the request
  • passphrase: the password of the API Key when creating the API
  • version: the key version number, current version number convention=2

**passphrase:**in the request parameters

  1. Use the API-Secret to encrypt the passphrase with HMAC-sha256, then pass the encrypted content through base64 encoding.
#Example for get algo list in python

import base64
import hashlib
import hmac
import time
import requests

url = 'https://www.kucoin.com/_api/miningpool/v1/external/algo/query'
api_key = "api_key"
api_secret = "api_secret"
api_passphrase = "api_passphrase"
now = int(time.time() * 1000)
params = {
    'key': api_key,
    'passphrase': base64.b64encode(
        hmac.new(api_secret.encode('utf-8'), api_passphrase.encode('utf-8'), hashlib.sha256).digest()),
    'timestamp': now,
    'version': 2
}
response = requests.get(url, params=params)
print(response.status_code)
print(response.json())
