Do I need a CareerStudioMax account?

No. Registering here creates a standalone Transformer API account — separate login, separate keys, independent of the main platform and of CSTM-1/CSTM-2's own developer accounts.

What happens after the daily limit?

Requests return 429 with the exact reset time until your daily window rolls over — no silent throttling.
