I am connecting to Compound Finance API but i am not getting the desired result

New Markets

** I have connected to the api successfully but it is output an empty list in most of the values except assert**

import json
import pandas as pd
import requests

url = ("https://api.compound.finance/api/v2/market_history/graph? asset=0xf5dce57282a584d2746faf1593d3121fcac444dc&min_block_timestamp=1556747900&max_block_timestamp=1559339000&num_buckets=10")
headers = {
'Content-Type': 'application/json'
}

res = requests.get(url, headers=headers)
res = requests.get(url).json()

** When i call res i get this**

{'asset': '0xf5dce57282a584d2746faf1593d3121fcac444dc',
'borrow_rates': [],
'error': {'error_code': 0, 'field_errors': {}, 'message': ''},
'exchange_rates': [],
'prices_usd': [],
'supply_rates': [],
'total_borrows_history': [],
'total_supply_history': []}
