Fetch Candlestick/Kline data from Binance API using Python (preferably requests) to get JSON Dat

Question

I am developing a telegram bot that fetches Candlestick Data from Binance API. I am unable to get JSON Data as a response. The following code is something that I tried.

 import requests 

 import json

 import urllib.request

`url = "https://api.binance.com/api/v1/klines"

response = requests.request("GET", url)
print(response.text)`

Desired Output:

[ [ 1499040000000, // Open time "0.01634790", // Open "0.80000000", // High "0.01575800", // Low "0.01577100", // Close "148976.11427815", // Volume 1499644799999, // Close time "2434.19055334", // Quote asset volume 308, // Number of trades "1756.87402397", // Taker buy base asset volume "28.46694368", // Taker buy quote asset volume "17928899.62484339" // Ignore ] ]

Question Edited:

The output that I am getting is:

 `{"code":-1102,"msg":"Mandatory parameter 'symbol' was not sent, was empty/null, or malformed."}'

Solution 1

you are missing the mandatory parameters symbol and interval, the query should be like this:

https://api.binance.com/api/v3/klines?symbol=BTCUSDT&interval=1h

you need to import only requests:

import requests

market = 'BTCUSDT'
tick_interval = '1h'

url = 'https://api.binance.com/api/v3/klines?symbol='+market+'&interval='+tick_interval
data = requests.get(url).json()

print(data)

Please check the official Binance REST API documentation here: https://github.com/binance/binance-spot-api-docs/blob/master/rest-api.md

Solution 2

The requests python package has a params, json argument, so you don't need to import any of those packages you are importing.

import requests

url = 'https://api.binance.com/api/v3/klines'
params = {
  'symbol': 'BTCUSDT',
  'interval': '1h'
}
response = requests.get(url, params=params)
print(response.json())

Is it possible to pass a list of symbols?

@HAßdøµ No you can't pass a list of symbols, please refer to the API documentation: github.com/binance/binance-spot-api-docs/blob/master/….

[Domenico]

the last line should be: print(response.json()) instead of: print(response.json)
