I just signed up for the Developer API (premium) and was put on the “beta wait list” (ouch! - insulted and waitlisted). I was curious if anyone has a ballpark estimate of the review time before approval. I was going to use the Search API with the 30 day lookback limit if that has any bearing on the matter. It is for a grad school project and it is time sensitive, so I may need to scrap my project topic if the approval time is tentatively long in the beta line.
