We have been using Xero (www.xero.com) and absolutely loving it for several years. They are web based and have an API.

They're getting pretty popular in New Zealand (we're they and we are based) but also gaining traction in Australia and the UK. They have a US version available as well but marketing seems to have been focused outside the US so far.

They're a listed company here in New Zealand so I expect they'll be here for quite some time.
