API for Options Firms?

Hi Everyone,

which firms provide an API to trade for Options?

(also if someone could provide rough execution/clearing costs)

Thanks.

 

anyone?

 

The obvious choice is interactive brokers.
Decent API connection, 70 cents per contract (1$ minimum) a little less if you trade larger lots and enough of them

OptionsXPress is another choice (web service api i think), not sure about their commission structure.

 

All ET threads eventually mention IB... It's the ET equivalent of Godwin's law.

 

Not to praise their features but I have a thinkorswim and a IB account.
I love TOS (support and platform) but I also love IB for their API and their commission structure. I'd be in a world of hurt if either broker decides to terminate my account
