US Postal Service has APIs

It turns-out that the US Postal Service has its own set of web APIs (and has had some of them for nearly three years). They offer five types of APIs: Address Information, Delivery Information, Rate Calculators, Shipping Labels, and Carrier Pickup. The programming model is a custom XML over HTTP approach. The API documentation is reasonably good yet has a certain 'governmental office' feel to it.

Thanks to an anonymous poster yesterday for adding this and there's now 125 APIs in the database.

Be sure to read the next API article: Windows Live Local APIs
