API to get daily price for Bitcoin.

[DeathAndTaxes]

Anyone know of any API to get Mt.Gox daily price information for Bitcoin?

There is:
http://bitcoincharts.com/t/trades.csv?symbol=mtgoxUSD&start=1315906316

but it returns every trade.

I just need daily price.  Would prefer volume weighted average price but opening price, closing price, simple avg price, just about anything on a daily basis would work

Something like this but for BTC:USD

About the closest that I know of where the data is ready-to-go comes from extracting the data from the html source for:
 - http://www.blockchain.info/charts/market-price?timespan=all

That's what I use to (manually) feed:
