# Wind power potential - capacity factor (Sugra derived)

`GET /api/v2/energy/wind`

Modelled wind power potential (capacity factor 0-1) at any coordinate worldwide, computed by Sugra from the Sugra Earth forecast spine's 10 m wind via a clean-room turbine power curve. A grid-derived free-rider (no new external fetch). v1 is a 10 m APPROXIMATION - not hub-height wind - and understates true hub-height potential.

## Query parameters

- `lat` number, required — Latitude, decimal degrees.
- `lon` number, required — Longitude, decimal degrees.

## Response `200`

    - `location` DemandLocation, required
      - `requested` object, required — The requested {lat, lon}.
      - `tile` string, required — Spine tile id serving this coordinate.
    - `wind_speed_10m_ms` number, required — 10 m wind speed, m/s.
    - `wind_direction_deg` number, required — Meteorological direction the wind blows FROM, degrees.
    - `capacity_factor` number, required — Modelled capacity factor [0,1] from the 10 m wind.

      - `institution` string, nullable
      - `model` string, nullable
      - `grid` string, nullable
      - `cycle` string, nullable
      - `valid_time` string, nullable — Valid time of the analysis snapshot (ISO 8601 UTC).
    - `attribution` DemandAttribution, required
      - `attribution` DemandAttributionEntry[] — The Sugra-derived entry first (no sovereign shield), then each contributing base model.
        - `registry_key` string, required
        - `source_name` string, required
        - `licence` string, nullable
        - `citation` string, nullable

      - `effective_reexport` string, required
    - `methodology` string, required
    - `disclaimer` string, required
  - `meta` SugraMeta, required — Metadata attached to every /api/v1/* response envelope.
    - `endpoint` string, required — Requested endpoint path.
    - `data_time` string, required — ISO 8601 UTC timestamp of the source data, not of the request.
    - `response_time` string, required — ISO 8601 UTC timestamp when this response was produced.
    - `provider` string, required — API name and version.
    - `source` string, nullable — Identifier of the primary upstream source used for this response.
    - `attribution` string, nullable — Human-readable attribution mandated by an upstream source (e.g. a securities regulator or self-regulatory organization). Present only on responses whose source requires the owner and source to be clearly identified. Do not remove or alter it when using the response.
    - `fallback_used` boolean, nullable — True when the primary source failed and a fallback produced the data.
    - `fallback_chain` string[], nullable — Ordered list of sources attempted, in the order they were tried.
    - `cached` boolean, nullable — True when this response was served from the internal cache.
    - `stale` boolean, nullable — True when the cached response was returned after the upstream rate-limited or errored. Clients can use this to detect degraded data.

## Other responses

- `401` — Missing or invalid `x-api-key` header.
- `422` — Validation Error
- `429` — Daily rate limit exceeded. Check `X-RateLimit-Reset` for the next window.
- `503` — Upstream source is temporarily unavailable. Retry after a short delay.
