UK Carbon Futures

UK ETS / UKA carbon futures.

Available Variants

/v1/futures/uk-carbon currently has exactly three documented endpoints: base, /historical, and /curve (curve verified live in production 2026-07-22). Do not build against /ohlc, /intraday, /spreads, or /spread-history for UK carbon unless those variants are added by the backend.

The canonical slug is uk-carbon (contract codes are UKA_FUTURES_*). The near-miss spellings uka-carbon, uka, and ukets-carbon are served as aliases of the same base, /historical, and /curve actions, but use uk-carbon in new integrations.

Front-month via /v1/prices

by_code=UKA_FUTURES on /v1/prices/latest (and the other /v1/prices/* endpoints) resolves to the current front-month contract — verified live 2026-09-11, it returned "code": "UKA_FUTURES_2026_09". Use it when you want the rolling front-month price without tracking contract expiry yourself.

Access

Requires Futures Data. It is included in Professional and above; other paid plans can add it for $39/month from Dashboard → Billing. A key without it receives 403 — see Access and limits.
