I'm just looking through API documentation, and I didn't come across the API calls for IB to check the number of shares available to short and the present shorting fee for shorting the stock.
https://www.interactivebrokers.com/en/?f=%2Fen%2Ftrading%2FViewShortableStocks.php%3Fcntry%3Dusa%26a
Is the sort of information I want to be able to query through the API.
To query the shorting fee rate itself you need to be logged into IB.
Apologies if this is covered in the API docs and I missed it.
Unfortunately, it's not something that we have good support for at this time. Depending on what tools and brokerage info you have, you might be able to get shorting availability into a CSV and then import it using Fetcher each morning. But there is no easy, pre-built API.
It's definitely something we want to add in the future.

Thanks for your answer Dan. Look forward to that feature.
Another question for you - what happens to a running algorithm if a stock that is being shorted presently gets recalled (as in the broker no longer has any inventory available).
The actual recall process is entirely done by your broker, according to your agreement with them. Quantopian will learn about it when your position changes - presumably some short position will close, or get smaller. When that happens, Quantopian automatically synchronizes your algorithm's portfolio to match the broker-reported portfolio.
There isn't a special handler for this kind of situation - we do a synchronization every minute, and this is one of the many cases that is handled by that.
