HTTP Error 404 from googlefinance in python 2.7

Question

In python 2.7 shell I ran the follwoings:

$from googlefinance import getQuotes
$import json
$from urllib2 import urlopen
$print json.dumps(getQuotes('AAPL'), indent=2)

Got error message on the 4th command as follows:

Traceback (most recent call last):

    raise HTTPError(req.get_full_url(), code, msg, hdrs, fp)
urllib2.HTTPError: HTTP Error 404: Not Found

Not sure whats going on. Here is an image of my activities.

Answer 1

It seems like Google Finance modified their URLs/endpoints and the googlefinance package has not been updated to reflect the change.

Since most of these changes are rather opaque to end-users (and the library you're using hasn't been updated in 2 years), you might have better luck dealing with the raw Google Finance response yourself.

The Google Finance Endpoint

You can retrieve information about a particular ticker symbol via the following URL:

https://finance.google.com/finance?output=json&q=TICKER_SYMBOL

The Response

Google Finance returns JSON results in this format

\n// [\n{\n"symbol" : "AAPL",\n"exchange" : "NASDAQ",\n"id": "22144",\n"t" 
: "AAPL",\n"e" : "NASDAQ",\n"name" : "Apple Inc."\n, "f_reuters_url" : 
"http:\\x2F\\x2Fstocks.us.reuters.com\\x2Fstocks\\x2Fratios.asp?rpc=66\\x26symbol=AAPL.O",\n"f_recent_quarter_date" : "Q3 (Jul \\x2717)",\n"f_annual_date" : "2016",\n"f_ttm_date" : "2015",\n"financials" :

    ... a lot more stuff ...
[\n]\n}]\n'

It can't be loaded by Python's JSON parser as-is because it has leading //, and wraps everything inside []. It also has Unicode-escaped characters in various strings that need to be decoded.

Complete code and parsing

I'm going to use the requests module for this, but if you want an example with the built-in urllib module, I can show that as well.

import json

import requests

rsp = requests.get('https://finance.google.com/finance?q=AAPL&output=json')

if rsp.status_code in (200,):

    # This magic here is to cut out various leading characters from the JSON 
    # response, as well as trailing stuff (a terminating ']\n' sequence), and then
    # we decode the escape sequences in the response
    # This then allows you to load the resulting string
    # with the JSON module.
    fin_data = json.loads(rsp.content[6:-2].decode('unicode_escape'))

    # print out some quote data
    print('Opening Price: {}'.format(fin_data['op']))
    print('Price/Earnings Ratio: {}'.format(fin_data['pe']))
    print('52-week high: {}'.format(fin_data['hi52']))
    print('52-week low: {}'.format(fin_data['lo52']))

This would output:

Opening Price: 162.71
Price/Earnings Ratio: 18.43
52-week high: 164.94
52-week low: 102.53

There is a lot more data that's included in a full ticker JSON than what I'm outputting, so it's up to you to decide how you want to use any of it.

Alternatives

Alternatively, you could use the yahoo-finance module, which is probably less likely to have issues like this as Yahoo still provide a real finance API.

If you are using Python 3.6 or 2.7, try using: Quandl https://www.quandl.com/ Use WIKI it seems to be stable example: Apple = quandl.get('WIKI/AAPL', start_date="2016-12-31", end_date="") Time series docs: https://docs.quandl.com/docs/time-series-2 If you make more than 50 requests Quandl requires a key(free to use)

Multiple stock details working on this endpoint with google stock ID
