Four new endpoints give an agent the same numbers our public pages show, with the sample size and the window every time. The MCP server (0.2.0) and the agent skill expose them, plus the Editorial Board, and trending now serves all twelve networks.
Until now an agent connected to ViralHunt could find what is trending and publish it. It can now answer the questions that come right after: when, with which hashtags, on which sound, and where.
GET /best-time): the weekday and hour the posts that went viral on a network were published, over the last 365 days, with the hit rate of each slot, the worst slot, today's best hours, proof posts, and every hour rotated to the time zone you ask for. Add a keyword and the slots are recomputed on posts about it; under 200 posts it says so and falls back.GET /hashtags): per network or across all, by engagement, posts or per post, or one hashtag broken down by network.GET /sounds): audio trending on TikTok, Instagram Reels and Douyin, cross-network sounds first, with the posts that used each one.GET /communities): subreddits ranked by peak score per 1,000 members, each with the best hours to post there, pace, flairs, top posts and similar communities; and Bluesky custom feeds with their top posts, authors and hashtags.Each response carries its sample size and its time window, and a confidence level where an hour is being named. An agent that quotes "Thursday at 8 pm, over 18,000 posts of the last year, 19.6% of them in the top 10%" is giving advice; one that quotes a bare hour is guessing. The API makes the first one the easy one.
Trending now serves Reddit, Mastodon, Tumblr and Hacker News alongside TikTok, Instagram, X, Facebook, Pinterest, Bluesky, Douyin and RSS, each with its own sorts and, where we hold two readings, how much a post moved between them.
The MCP server gains four tools for the endpoints above and five for the Editorial Board (context, create a card, move it, your cards, comments), so an agent can hand content to a team instead of publishing it directly. The agent skill documents all of it. Both are at viralhunt.io/api.
