How to create a program that enters the web and takes the data of the stock exchange [closed]

API for stock quotes of stock

• link

Rate tables:

• link

Using with Python 3

In Python 3 you can use urllib.request with json

import json
import urllib.request

url = "http://api.bolsafinanceira.com:8080/composition/?token=<seu-token>&codelist=ibovespa,ibrx50"

with urllib.request.urlopen(urlData) as f:
   data = f.read()
   encoding = f.info().get_content_charset('utf-8')
   json.loads(data.decode(encoding))

Or use import requests

  

To install, use the command:

 pip install requests

     

Or pipenv (depends on your environment)

 pipenv install requests

It should look like this:

import requests

url = 'http://api.bolsafinanceira.com:8080/composition/?token=<seu-token>&codelist=ibovespa,ibrx50';

r = requests.get(url, print=pretty')

# Exibe a resposta
print(r.json())
