Technical details
Endpoint
POSThttps://api.vextorium.com/v1/mastodon-trending-tags?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need real-time trending hashtag data from a specific Mastodon/fediverse instance, including both daily and 7-day usage statistics and account counts. Prefer it over generic social media trend APIs when the user specifically wants fediverse or Mastodon data rather than Twitter/X trends.
Side effects
- Invalid or unreachable Mastodon instance returns an error or empty result
- Instance does not expose public trending-tags API (some instances disable it)
- Limit parameter out of range may be clamped or cause an error
- Network timeout if the Mastodon instance is slow to respond
