Seismic-only discriminant analysis.

Evaluates mb:Ms ratio, P/S amplitude, depth, first motion
polarity, and source complexity.  Faster than full multi-physics
analysis when only seismic data is available.

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

## Query parameters

- `x_api_key` string, nullable
