# Wind Turbine Velocity Change

`POST /api/v1/frontier/wind/velocity-change`

## Request

- Base URL: `https://www.deepmapai.com`
- URL: `https://www.deepmapai.com/api/v1/frontier/wind/velocity-change`
- Auth: none declared

Detect relative seismic velocity changes (dv/v) between two time windows.

Compares cross-correlated Green's functions from two time
periods using stretching or doublet techniques to measure
subtle changes in subsurface velocity.  Positive dv/v may
indicate rising water tables or increased pore pressure.
**Pricing:** Included in subscription tiers (legacy list price: GET /api/v1/billing/pricing).

Parameters (JSON body):
- waveform1 : dict -- Reference Green's function waveform (required)
- waveform2 : dict -- Current Green's function waveform (required)
- frequency_band_hz : list[float] -- [min_freq, max_freq] in Hz (required)

## Query parameters

- `x_api_key` string, nullable

## Request body

- object

## Response `200`

Successful Response

- unknown

## Other responses

- `422`: Validation Error
