What Hashtag.org Hashtag Metrics is
Hashtag.org Hashtag Metrics provides free analytics on hashtag usage, related tags, top posts, engagement, and posting hours. The web tool requires no login, and the same metrics can be retrieved as JSON through the `/api/hashtags/<tag>` endpoint. Its directory offers browsing across 1,251,230 measured tags. Mastodon public tags, trends, and search APIs supply usage counts, while Bluesky’s public search API supplies post metrics. The Mastodon counts cover roughly seven days; Bluesky metrics reflect the latest sample of posts. Each figure identifies its source and fetch time, and values the service cannot measure appear as a dash. Metrics for X, Instagram, and TikTok are absent because their numbers are behind paid APIs. The service also describes a public-bid auction for claiming a hashtag as a #name on the hashtag.org network. Hashtag Metrics is available on the web and through an API.
