May i know, what is the documentation for batch API calls in Finnhub? Where can i get it?

[ProgrammingTed]

Hi, i am new here, I tried many times to call the batch API calls in Finnhub to improve the performance of retrieving the data, but I also failed, and I can't find any documentation online. Where can I have more informations for my references?

dataframe_result = pd.DataFrame(columns= my_columns)
for symbol_strings in symbol_strings[:1]:

#Request the quote data (support batch API calls?)
batch_api_url_quote= f'https://finnhub.io/api/v1/quote?symbol=
{symbol_2}&token={CLOUD_API_TOKEN}'
quote_data= requests.get(batch_api_url_quote).json()
print(batch_api_url_quote)

#Request the profile data (support batch API calls?)
batch_api_url_quote = f'https://finnhub.io/api/v1/profile2?symbol=
{symbol_2}&token={CLOUD_API_TOKEN}'
price_data = requests.get(api_url).json()

#Combine both data dictionaries
#final_data = {**profile_data, **price_data}
#print(final_data)

Thanks
