Is there an API that would let me access my AMEX transactions? How do Mint or any other finance websites export my data? If so, is it free?

A:
Take a look at open financial exchange.
American Express appears to support this.

Mint uses the services of Yodlee (see here), a firm that essentially acts as middleware between banks and companies like Mint.
You might be interested in Yodlee's Account Data Gathering API but it looks like it is something that requires a formal agreement, and access to the API probably needs to be paid for..
MasterCard are also looking at releasing an API (see here) so maybe AMEX will follow suit?
