Why This Matters for Operators

Content teams spend hours manually hunting trends, guessing post timing, and copy-pasting posts across networks. ViralHunt turns that into one agent-drivable loop - every number (best time, hashtag strength, trend velocity) comes with its sample size and time window, so an agent can state how much to trust it instead of hallucinating confidence. The growth_24h field on trending posts shows how much a post moved between readings, which is the difference between catching a trend early and chasing it late.
