GET /v1/latest/:zone

unprobed

Most recent value of every metric one electricity zone publishes (wholesale price, demand, interchange; generation mix for GB and US-CAISO; carbon intensity for GB), each with unit and timestamp. Note European day-ahead prices can carry a timestamp up to ~36h ahead. 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.

Try it (unpaid: shows the 402)

curl -si -X GET 'https://api.grid-hub.app/v1/latest/:zone' -H 'accept: application/json'

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.
