Energy API Use Cases: Mark Oil, Hedge Gas, and Book EUA

An energy price API is useful when you persist the same three marks every morning: oil, gas, and carbon. On Energy-API that is GET https://energy-api.com/api/v1/latest with query api_key. Official docs mix dated 2026-06-11 prints BRENT_CRUDE 74.82 USD, TTF_GAS 38.15 EUR, and EUA_CO2 67.40 EUR. BRENT_CRUDE is the EIA/FRED Europe spot, not an ICE futures print.

Starter is $19.99/mo (5,000 calls, 5 symbols) with a 7-day trial / 50 calls. Do not send base=USD if you need EUR rows — the mix is base: MIXED. There is no MCP. Docs: energy-api.com/docs.

Use cases

• Mark a crude book. Persist rates.BRENT_CRUDE and currencies.BRENT_CRUDE (USD in this fixture).
• Hedge EU gas. TTF_GAS is EUR here. For the US print, call /gas/latest or /symbols?category=gas — official catalog includes HENRY_HUB (USD/MMBtu, EIA/FRED).
• Book EUA for a power desk. EUA_CO2 67.40 EUR on the same dated mix. Pair with OMIE_ES_DA 82.30 if you also mark Spain day-ahead.
