One story I've heard is that back in the 1980s, American Express
developed an expert system (which might still be in use) for approving
credit card transactions. As I understand, AmEx doesn't assign a
specific credit limit to an account; rather, they approve transactions
on a case-by-case basis depending on various factors such as the
account's existing balance, payment history, size of the requested
transaction, and sizes of past transactions. (So e.g. if you have a
history of making large purchases and paying them off promptly,
they'll keep allowing you to do that.)

Anyway, I recall being told that somewhere AmEx had a bank of
Symbolics machines running this expert system, making these
transaction approval decisions in real time. That may not be exactly
what you have in mind, but I think it demonstrates that these machines
were perfectly capable of providing E-commerce services.
