GET /v1/brief/:zone

unprobed

Interpretation-ready snapshot of one electricity zone: current wholesale price and demand (plus carbon intensity for GB) each ranked against the zone's own trailing 30-day distribution, 24h trend, and a one-sentence summary. Use for 'is power cheap or expensive in {zone} right now'. 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.

The catalog declares GET. A 402 answer carries the payment requirements in the JSON body and, for x402 v2, base64 in the PAYMENT-REQUIRED header. This page never sends a payment.
