Watch this vault

Pay per day for an alert when this vault's result changes, in your inbox and at your webhook if you register one, and for a shorter re-check cadence (the watcher's default is every 60 minutes for subscribed vaults, at most once a day for the rest). Every result stays public either way; a subscription buys delivery and freshness.
