Pandas question

[new2datasci]

Pulling from polygon.io API.
(JSON Object Response example at bottom)
green text is where im stuck
red text is from documentation
this response object from the api has no top-level key for the json.
Read https://medium.com/swlh/converting-neste...106c59976e
2/3 down they have a json_normalize example
it uses a top-level key and the response object I am getting does not have one.
what do i put in my highlighted line below?

from documentation:

pandas.json_normalize(data, record_path=None, meta=None, meta_prefix=None, record_prefix=None, errors='raise', sep='.', max_level=None)

See my work right below minus API information etc(results is the information from the API's GET request:

results = requests.get(url).json()
df = pd.DataFrame.from_records(results,columns=['symbol','isUTC','day','open','close','openTrades','closingTrades'])
FIELDS = ["symbol", "isUTC", "day", "open", "openTrades.s",'openTrades.p','openTrades.x','openTrades.t','openTrades.c','closingTrades.s','closingTrades.p','closingTrades.x','closingTrades.t','closingTrades.c']
df = pd.json_normalize(results)
df[FIELDS]

Output:

Please, use proper tags when post code, traceback, output, etc. This time I have added tags for you.
