Andrew Trice has an interesting post/example using data from StrikeIron. As he mentions, their Super Data Pack (free up to 10,000 hits/month) offers lots of interesting data:

  • US Census data by zip code
  • Historical currency exchange rates
  • Historical prime interest rates
  • Airport statistics
  • Biodeisel stations
  • And much more…

Their paid web services include an SMS message sending service, a postal address verification service, and others.

StrikeIron also publishes a Global Directory which lists over 1000 web services offered by themselves and others. This made me wonder what other web service directories are out there. A quick Google search found these:

Also, ProgrammableWeb.com‘s listing of APIs includes web services and lots of other great resources.

What are your favorite web services and/or directories?

Do they have a crossdomain.xml file, so that we can access them from Flex without a proxy?
