# Real-time power grid fuel mix

`GET /api/grid/fuel-mix`

## Request

- Base URL: `https://dchub.cloud`
- URL: `https://dchub.cloud/api/grid/fuel-mix`
- Auth: API key in header `X-API-Key`

What a US grid is generating from RIGHT NOW — MW and share by fuel (gas, nuclear, coal, wind, solar, hydro, storage) with the reading's own timestamp. Use this instead of quoting an annual average when the question is about current conditions. Covers the seven US ISOs/RTOs only — not utility-level or non-US grids. Requires an X-API-Key header for a key on any paid DC Hub plan, or a key with full-answer access. The free key from /api/v1/keys/claim does not open it.

## Query parameters

- `iso` 'ERCOT' | 'PJM' | 'CAISO' | 'MISO' | 'SPP' | 'NYISO' | 'ISONE'

## Response `200`

Grid fuel mix data

## Other responses
