Do you provide any access to raw tick-by-tick event data or just bars?
How do you secure your users' scripts so they don't worry about you stealing their ideas or front-running them?
It might be useful to provide FX rates as a feed so users could come up with a synthetic price for non-USD pairs.
For guys who want to work passive orders, an API where they can pass a dictionary of prices/sizes they're willing to buy/sell at into a goal seeking algorithm that handles canceling/placing individual orders might be a better match and more convenient.
