- URL: `https://www.deepmapai.com/api/v1/cross/fault-water/profile`
- Auth: none declared

Compute Vp/Vs depth profile at a location.

Uses ambient noise cross-correlation between two RS stations to
extract group velocity dispersion and invert for Vp, Vs, and
Vp/Vs at depth. Optionally cross-validates with magnetotelluric
resistivity data if available.

**Pricing:** Included in subscription tiers (legacy list price: GET /api/v1/billing/pricing).

Parameters (JSON body)
----------------------
lat : float

lon : float
    Longitude of target location.
station_pair : list of str
    Two RS station codes to use for cross-correlation.
max_depth_km : float, optional
    Maximum depth for inversion (default 50 km).
include_mt : bool, optional
    Include synthetic MT cross-validation (default True).
