No. Dedicated API pack credits are one-time purchases and do not expire.
Dedicated API packs are API-only. Max plan image credits are shared across Studio, Agent and the API, so each use deducts from the same balance. Credits included with Yearly or Lifetime membership also remain usable on the API.
The API supports CV-1, CV-2 Standard, CV-2 Max, CV-3 Fast and CV-3 Fine. CV-2 Standard is the default.
CV-1 costs 1 credit at 2K and 2 at 4K. CV-2 Standard costs 1 and 2, and CV-2 Max costs 2 and 4. CV-3 Fast and CV-3 Fine each cost 1 and 2 in Standard mode, and 2 and 4 in Max mode.
