Depends on your business model, how useful/unique the API is and many other things.
I would suggest making it free to get an API key and run a small number of queries (or a low rate limit). That allows devs to build against your API without needing to take out their credit card. Beyond that, I'd suggest something like $1 per thousand calls and add a bulk discount if your larger users are providing extra value to you.
I think it's important to consider the shift in home dynamics if someone is WFH vs in office. WFH gives a lot more flexibility to help out with house chores, childcare etc. In contrast, in office work removes this possibility which can be either a feature or a bug. Talking to a lot of old timey in office proponents, it sounds like many of them shifted housework/childcare to a partner and had a good time mostly because they weren't doing any of that work.
Do it! Don't tell them you drive SCCA though the judges will absolutely give you a hard time. My only advice is that passes don't matter in lemons. Stay out of the pits, drive clean laps, and have similar skill drivers and you'll be quick.
From what I understand it's all ego and ethics from him - the board is not stoked about the risk involved and the potential upside. I think Epic has something to gain by removing app store fees for medium sized games though - that would put money back in their pocket creating an opportunity to charge more for Unreal revshare.
