# Resource Analysis

`POST /api/v1/analysis/resources`

## Request

- Base URL: `https://api.bellatorsi.com` (the document declares no server; this is the origin it was published from)
- URL: `https://api.bellatorsi.com/api/v1/analysis/resources`
- Auth: none declared

Run a time-phased resource analysis on a schedule.

Accepts a schedule payload (tasks), optional resource availability
declarations, and analysis options. Returns demand profiles per resource,
over-allocation periods, leveling candidates, and a composite risk score.
