I'm wondering what API methods there are to determine a company's market cap, i.e. (number of shares issued) * (price per share).

I know IQfeed and perhaps Yahoo will do this - does anyone know of any other API's that will do the job?

I know you mentioned that you already know about Yahoo's ability to do this. However, I thought I'd add the following snippet on how to do this with Yahoo. It's a trivial HTTP Get, and is likely the quickest and easiest way to get the information you're after:

> curl "http://download.finance.yahoo.com/d/quotes.csv?s=CSCO&f=j1"
86.991B

That will return a single result with one entry, which is the market cap of the stock you supplied. You can also supply more than one stock:

> curl "http://download.finance.yahoo.com/d/quotes.csv?s=CSCO,AAPL&f=j1"
86.991B
355.9B

See Yahoo Query Language (YQL) blog: Getting stock information with YQL and open data tables.

Go to the YQL console, and use the following query:

select MarketCapitalization from yahoo.finance.quotes where symbol in ("YHOO","AAPL")

Here is key part of the result:

<results>
    <quote>
        <MarketCapitalization>20.508B</MarketCapitalization>
    </quote>
    <quote>
        <MarketCapitalization>317.5B</MarketCapitalization>
    </quote>
</results>

Once you have the result in .xml, its easy to query it using LINQ in C#.

The Zacks API should have this data, see http://www.zacksdata.com/zacks-data-api
