Ask HN: What Would you want in a government API?

I'm marveling over the new whitehouse.gov and thinking that the government should have an API. I imagine it would create a thousands of government jobs, boost every sector of hardware sales, foster the creation of thousands of start ups and bring accountability and transparency to government, among other things. I'd say my first request would be this function:

getEveryDollarSpent, which would accept as parameters paidTo, authorizedBy, minDollars, maxDollars, dateFrom and dateTo.

What's yours?
