I took them up on their challenge of integrating in 15 minutes, and have been using them ever since. Delightful API/clients, support for a large number of services (though, no DHL).

Forwarded us through 6 sales agents and the last one even didn't understand what we need (after 50 emails sent). Looking good from outside, bad inside.

Are not friendly at all.

Pros:

good idea

Cons:

sales agent are awful

Not friendly at all

This is a simple RESTful API for the major US postal services that allows you to get real time shipping rates, address validation and print pre-paid shipping labels.

I use them for StartupThreads. The alternatives to this are a bit difficult to work with. Once they get integrated in some of the big ecommerce platforms, they will explode.

Baller team too, e.g. the homie Justin Mares.
