# Digest Subscribe

`POST /public/digest-subscribe`

## Request

- Base URL: `https://api.nicheangle.com` (the document declares no server; this is the origin it was published from)
- URL: `https://api.nicheangle.com/public/digest-subscribe`
- Auth: none declared

Subscribe to the WEEKLY ROLLUP (the Underreported list) — a single, niche-agnostic
editorial email, NOT a per-niche scan (that's the paid watched-niches feature). Capture-
only for now: the email lands in the waitlist table tagged `source='weekly_rollup'` (a
distinct, filterable list — keep it OUT of any pre-launch invite blast), and the page it
converted on rides a PostHog event as a lead attribute. The rollup SEND + proper list
management ship with the Underreported Index build.
