- Auth: none declared

Compute neutrino absorption density profile at a target location.

Uses multi-angle Beer-Lambert absorption modeling with the global
detector network to reconstruct subsurface density at the specified
depth.  Returns absorption profile, density contrast, and detector
baseline geometry.

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