Creates a viral alert: we watch a TikTok, Instagram or YouTube profile and email the address you give when it publishes a post whose outlier score (views divided by the profile's own average) reaches minOutlierScore (default 3, minimum 1.5) within postAgeDays of posting (default 7, max 30). Identify the profile by profileId, platform+handle, or a public URL; it must already be in the database (crawl_profile it first if not). Setting up, listing and deleting alerts is free. Two things cost credits: the refresh crawl that keeps the profile fresh (10 credits per run, daily by default, started for you if you are not already monitoring the profile with track_profile) and each alert email actually sent (5 credits). Limits: one alert email per destination address per day, sent around sendHour in your timezone (defaults 9, UTC) and bundling every alert that fired; 3 emails per alert in total, after which the alert ends; expiresInDays (default 30, max 90) ends it regardless; 25 active alerts per account. A post can trigger an alert only once. Your account email needs no confirmation; any other address receives a confirmation link first and nothing is sent until it is clicked. Every alert email has its own stop link. Calling again for the same profile and address updates the settings instead of creating a duplicate.

Cost: free.
