# Ulf Mt Profile

`POST /api/v1/cross/ulf-mt/profile`

## Request

- Base URL: `https://www.deepmapai.com`
- URL: `https://www.deepmapai.com/api/v1/cross/ulf-mt/profile`
- Auth: none declared

Resistivity-depth profile to mantle depths from ULF MT analysis.

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

Combines INTERMAGNET magnetometer B-field data with Raspberry Shake
seismic ground motion to estimate electromagnetic impedance at ULF
frequencies (0.001-0.1 Hz), yielding resistivity structure from
mid-crust (~16 km) to upper mantle (~159 km).

## Query parameters

- `x_api_key` string, nullable

## Request body

- BodyUlfMtProfileApiV1CrossUlfMtProfilePost
  - `mag_station` string, required: INTERMAGNET station code (e.g. BOU, FRD, TUC)
  - `rs_station` string: Raspberry Shake station code for seismic proxy
  - `hours` integer: Hours of data to process (12-168)
  - `melt_threshold` number: Resistivity threshold for melt detection (ohm-m)

## Response `200`

Successful Response

- unknown

## Other responses
