GET /v1/power/board25 credits
Electricity projects, capacity, queue rates and utility exposure. Reads the existing dataset service and needs a key on an account with a plan; every plan reads every live dataset in full. Cached market reads can refresh their source data. Unknown, empty and repeated parameters are rejected. History and coverage metadata are null when the stored service cannot establish them.
