unprobed
Historical price time series for one electricity zone, oldest-first, max 31 days per call (start/end are Unix seconds; default last 24h; limit caps rows). Use for trends and backtests; use /v1/latest or /v1/brief for current values. Zone ids from /v1/zones.
Verdict: not verified by an unpaid GET. not probed yet. This says nothing about whether the route works when called as declared.
