# Create Hunch

`POST /api/v1/hunches`

## Request

- Base URL: `https://api.cohearence.app` (the document declares no server; this is the origin it was published from)
- URL: `https://api.cohearence.app/api/v1/hunches`
- Auth: HTTP bearer

Create a hunch from the save sheet, baselining it server-side.

Body: ``{predictor_metric_id, response_metric_id, lag_days?, method?,
preferred_lens?, hypothesis?, window_start?, window_end?, tz?}``. The
window defaults to the trailing year. Creation requires a computable
baseline (>= MIN_CORR_N overlapping days) — a hunch is a promotion of a
computed relationship, never a blind bookmark.

## Request body

- object

## Response `201`
