# Strain Infrastructure Slow Slip

`POST /api/v1/strain/infrastructure/slow-slip`

## Request

- Base URL: `https://www.deepmapai.com`
- URL: `https://www.deepmapai.com/api/v1/strain/infrastructure/slow-slip`
- Auth: none declared

Detect slow-slip events from noise-cleaned borehole strain.

Runs full analysis pipeline (fetch strain -> noise model ->
spectral subtraction -> transient detection -> slow-slip
classification) for a named site.

Required fields: ``site`` (string, e.g. "cascadia", "milford")
Optional fields: ``use_demo`` (bool, default False),
    ``days`` (int, 1-30, default 14),
    ``threshold_sigma`` (float, default 3.0)

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

Returns slow-slip probability, transient detection results,
geodetic moment rate, Coulomb stress change, and equivalent
moment magnitude.
