For months I've been using a url like this, from perl:

http://finance.yahoo.com/d/quotes.csv?s=$s&f=ynl1 #returns yield, name, price;

Today, 11/1/17, it suddenly returns a 999 error.

Is this a glitch, or has Yahoo terminated the service?

I get the error even if I enter the URL directly into a browser as, eg:

http://finance.yahoo.com/d/quotes.csv?s=INTC&f=ynl1

so it doesn't seem to be a 'crumb' problem.

Note: This is NOT a question which has been answered in the past! It was working yesterday.That it happened on the first of the month is suspicious.

I'm voting to close this question as off-topic because this is not the Yahoo site status. We're not support for any third-party off site location or vendor. Contact that site directly to inquire about their status. This site is for programming related questions.Rob
I am facing the same issue as well on my side, it was all good yesterday. Anyone have a working API code?Dennis
Many people are having this problem, but congratulations - your site remains pure.user1067305
They change public type to private for some tables, but (server-side, without yahoo login, only with app key and app secret) auth api doesn't existSalavat
It seems like they know about the issue, and intended to fix it. forums.yahoo.net/t5/Known-issues-and-updates/…despecher

Yahoo confirmed that they terminated the service:

It has come to our attention that this service is being used in violation of the Yahoo Terms of Service. As such, the service is being discontinued. For all future markets and equities data research, please refer to finance.yahoo.com .

As noted in the other answers and elsewhere (e.g. https://stackguides.com/questions/47076404/currency-helper-of-yahoo-sorry-unable-to-process-request-at-this-time-erro/47096766#47096766), Yahoo has indeed ceased operation of the Yahoo Finance API. However, as a workaround, you can access a trove of financial information, in JSON format, for a given ticker symbol, by doing a HTTPS GET request to: https://finance.yahoo.com/quote/SYMBOL (e.g. https://finance.yahoo.com/quote/MSFT). If you do a GET request to the above URL, you'll see that the financial data is contained within the response in JSON format. The following python3 script shows how you can parse individual values that you may be interested in:

import requests
import json

symbol='MSFT'
url='https://finance.yahoo.com/quote/' + symbol
resp = requests.get(url)

#parse the section from the html document containing the raw json data that we need
#you can write jsonstr to a file, then open the file in a web browser to browse the structure of the json data
r=str(resp.content, 'utf-8')
i1=0
i1=r.find('root.App.main', i1)
i1=r.find('{', i1)
i2=r.find("\n", i1)
i2=r.rfind(';', i1, i2)
jsonstr=r[i1:i2]      


#load the raw json data into a python data object
data = json.loads(jsonstr)

#pull the values that we are interested in 
name=data['context']['dispatcher']['stores']['QuoteSummaryStore']['price']['shortName']
price=data['context']['dispatcher']['stores']['QuoteSummaryStore']['price']['regularMarketPrice']['raw']
change=data['context']['dispatcher']['stores']['QuoteSummaryStore']['price']['regularMarketChange']['raw']
shares_outstanding=data['context']['dispatcher']['stores']['QuoteSummaryStore']['defaultKeyStatistics']['sharesOutstanding']['raw']
market_cap=data['context']['dispatcher']['stores']['QuoteSummaryStore']['summaryDetail']['marketCap']['raw']
trailing_pe=data['context']['dispatcher']['stores']['QuoteSummaryStore']['summaryDetail']['trailingPE']['raw']
earnings_per_share=data['context']['dispatcher']['stores']['QuoteSummaryStore']['defaultKeyStatistics']['trailingEps']['raw']
forward_annual_dividend_rate=data['context']['dispatcher']['stores']['QuoteSummaryStore']['summaryDetail']['dividendRate']['raw']
forward_annual_dividend_yield=data['context']['dispatcher']['stores']['QuoteSummaryStore']['summaryDetail']['dividendYield']['raw']

#print the values
print('Symbol:', symbol)
print('Name:', name)
print('Price:', price)
print('Change:', change)
print('Shares Outstanding:', shares_outstanding)
print('Market Cap:', market_cap)
print('Trailing PE:', trailing_pe)
print('Earnings Per Share:', earnings_per_share)
print('Forward Annual Dividend Rate:', forward_annual_dividend_rate)
print('Forward_annual_dividend_yield:', forward_annual_dividend_yield)

There is still a way to get this data by querying some APIs used by the finance.yahoo.com page. Not sure if Yahoo will be supporting it long term as the previous API was (hopefully they will).

I adapted the method used by https://github.com/pstadler/ticker.sh into the following python hack that takes a list of symbols from the command line and outputs some of the variables as a csv:

#!/usr/bin/env python

import sys
import time
import requests

if len(sys.argv) < 2:
    print("missing parameters: <symbol> ...")
    exit()

apiEndpoint = "https://query1.finance.yahoo.com/v7/finance/quote"
fields = [
    'symbol',
    'regularMarketVolume',
    'regularMarketPrice',
    'regularMarketDayHigh',
    'regularMarketDayLow',
    'regularMarketTime',
    'regularMarketChangePercent']
fields = ','.join(fields)
symbols = sys.argv[1:]
symbols = ','.join(symbols)
payload = {
    'lang': 'en-US',
    'region': 'US',
    'corsDomain': 'finance.yahoo.com',
    'fields': fields,
    'symbols': symbols}
r = requests.get(apiEndpoint, params=payload)
for i in r.json()['quoteResponse']['result']:
    if 'regularMarketPrice' in i:
        a = []
        a.append(i['symbol'])
        a.append(i['regularMarketPrice'])
        a.append(time.strftime(
            '%Y-%m-%d %H:%M:%S', time.localtime(i['regularMarketTime'])))
        a.append(i['regularMarketChangePercent'])
        a.append(i['regularMarketVolume'])
        a.append("{0:.2f} - {1:.2f}".format(
            i['regularMarketDayLow'], i['regularMarketDayHigh']))
        print(",".join([str(e) for e in a]))

Sample Run:

$ ./getquotePy.py AAPL GOOGL
AAPL,174.5342,2017-11-07 17:21:28,0.1630961,19905458,173.60 - 173.60
GOOGL,1048.6753,2017-11-07 17:21:22,0.5749836,840447,1043.00 - 1043.00

var API = "https://query1.finance.yahoo.com/v7/finance/quote?symbols=AAPL"; $.getJSON(API, function (json) {...});call throws this error: No 'Access-Control-Allow-Origin' header is present on the requested resource. Origin 'http://www.microplan.at/sar' is therefore not allowed access.

My Python program using Yahoo Finance has recently stopped working properly, but it didn't return that error, it just replaced stock prices with 0's. I initially saw this when I debugged and then, when I went to the yahoo finance URLS for those stocks, I confirmed the error. Since the actual data is messed up, I don't think the work-arounds that have been suggested would fix my problems. Is this likely related to yahoo discontinuing their API? I can't understand what could explain this.

Examples:
