Says there’s a REST API?
Looks like it's 500k calls per month per Apple Developer Program account, so essentially $99/yr. Not totally unreasonable pricing, although I wish I could buy it a la carte. It's a bit out of my price range for hobby projects. If I ever start developing apps for my family members (who mostly have iPhones at this point) though this will be a nice freebie to come with that. Ah well.
That limits the number of use cases quite dramatically.
Here's the pricing for those that might need >500k/mo. It looks like it won't be available until after this hits beta, but it looks to be $50/mo extra for each 1m calls (plus the price of a membership).
