# PingWhen

> Watch a URL. Get pinged when it changes or dies. Alerts go to email, SMS (US/CA), or a signed HTTPS webhook. Paid plans only: Starter $9/mo (10 watches, every 15 min), Plus $19/mo (40 watches, every 5 min). Agents pay the same Stripe subscription as humans.

We watch the HTML we receive (visible text, hashed); JavaScript-only pages are not supported. Create a watch with POST /v1/watches; the response includes a Stripe checkout_url for a human (or authorized agent) to pay. Poll until status=active.
