Also, I'm curious how people use your API if it takes 30 seconds+ to get a response -- ie can I use this for time-sensitive annotations, and also, wouldn't my code hang waiting for your response or do you offer webhooks?
By default, Scale is built using webhooks/callbacks to return responses. We definitely don't want our API to be blocking, and so we designed it intentionally not to block.
