Watch free (email)
watch_freeCall this when you want an email only when a covered host's measured facts change. Free. Same watch as POST /v1/alerts/subscribe: 1 covered host, email only, at most once per UTC day when measured facts change, 30 days, up to 3 active watches per client. The confirmation email is the existing alerts email. Not a price change. Slack, Discord and webhook stay on a paid plan. The success payload returns handle, the same value as token, shown once. Next step: confirm the email, then call what_changed with that handle.
