Is there any sort of API that just offers a simple symbol lookup service? i.e., input a company name and it will tell you the ticker symbol? I\'ve tried just screen-scraping Google Finance, but after a little while it rate limits you and you have to enter a CAPTCHA. I\'m trying to batch-lookup about 2000 ticker symbols. Any ideas?

You can use yahoo's symbol lookup like so:

http://d.yimg.com/autoc.finance.yahoo.com/autoc?query=yahoo&callback=YAHOO.Finance.SymbolSuggest.ssCallback

Where query is the company name.

You'll get something like this in return:

YAHOO.Finance.SymbolSuggest.ssCallback(
{
    "ResultSet": {
        "Query": "ya",
        "Result": [
            {
                "symbol": "YHOO",
                "name": "Yahoo! Inc.",
                "exch": "NMS",
                "type": "S",
                "exchDisp": "NASDAQ"
            },
            {

                "name": "Yamana Gold, Inc.",
                "exch": "NYQ",

                "exchDisp": "NYSE"
            },
            {

                "exch": "NYQ",

                "exchDisp": "NYSE"
            },
            {

                "name": "YAMANA GOLD INC COM NPV",

                "type": "S",
                "exchDisp": "Toronto"
            },
            {

            {

            {

                "name": "YANGTZEKIANG",
                "exch": "HKG",
                "type": "S",
                "exchDisp": "Hong Kong"

            {

                "name": "Yadkin Valley Financial Corp.",
                "exch": "NMS",
                "type": "S",
                "exchDisp": "NASDAQ"
            }
        ]
    }
}
)

Which is JSON and very easy to work with.

Hush... don't tell anybody.

Google Finance does let you retrieve up to 100 stock quotes at once using the following URL:

www.google.com/finance/info?infotype=infoquoteall&q=[ticker1],[ticker2],...,[tickern]

For example:

www.google.com/finance/info?infotype=infoquoteall&q=C,JPM,AIG

Someone has deciphered the available fields here:

http://qsb-mac.googlecode.com/svn/trunk/Vermilion/Modules/StockQuoter/StockQuoter.py

The current price ("l") is real-time and the delay is on par with Yahoo Finance. There are a few quirks you should be aware of. A handful of stocks require an exchange prefix. For example, if you query "BTIM", you'll get a "Bad Request" error but "AMEX:BTIM" works. A few stocks don't work even with the exchange prefix. For example, querying "FTWRD" and "NASDAQ:FTWRD" both generate "Bad Request" errors even though Google Finance does have information for this NASDAQ stock.

The "el" field, if present, tells you the current pre-market or after-hours price.

回答3:

You can send an HTTP request to http://finance.yahoo.com requesting symbols, names, quotes, and all sorts of other data. Data is returned as a .CSV so you can request multiple symbols in one query.

So if you send:

http://finance.yahoo.com/d/quotes.csv?s=MSFT+F+ATT&f=sn

You'll get back something like:

"MSFT","Microsoft Corp"
"F","FORD MOTOR CO"
"ATT","AT&T"

Here is an article called Downloading Yahoo Data which includes the various tags used to request the data.

回答4:

The NASDAQ site hosts separate CSV lists for ticker symbols in each stock exchange (NYSE, AMEX and NASDAQ). You need to complete the captcha and get the CSV dump.

回答5:

If you didn't want to sign up for a service, I'd probably go back to the exchanges themselves; most of them aren't CAPTCHAed yet...

The symbol lookup page for:

• NYSE is at http://www.nyse.com/interface/html/SymbolLookup.html
• NASDAQ is at http://www.nasdaq.com/asp/NasdaqSymLookup2.asp?mode=stock
• London Stock Exchange is at http://www.londonstockexchange.com/en-gb/pricesnews/prices/Trigger/genericsearch.htm
• ASX is at http://www.asx.com.au/asx/research/codeLookup.do

etc...

回答6:

Use YQL and you don't need to worry. It's a query language by Yahoo and you can get all the stock data including the name of the company for the ticker. It's a REST API and it returns the results via XML or JSON. I have a full tutorial and source code on my site take a look: http://www.jarloo.com/yahoo-stock-symbol-lookup/

回答7:

Currently, the NASDAQ web site publicly provides CSV files containing bulk listings -- it is broken up by first letter.

回答8:

Google Finance has an API - you probably have to apply for a developers key, but at least you'd save yourself the hassle of screen-scraping: http://code.google.com/apis/finance/reference.html

回答9:

Your best bets are probably going with one of the other lookup services (still screen-scraping), and checking whether they don't require CAPTCHAs.

• Yahoo Finance
• MSN Money
• AlphaTrade Finance

The last appears the least likely to require a CAPTCHA at any point, but it's worth checking all three.

回答10:

Use YQL: a sql-like language to retrieve stuff from public api's: YQL Console (external link)

It gives you a nice XML file to work with!

You can use the "Company Search" operation in the Company Fundamentals API here: http://www.mergent.com/servius/
