Technical details
Endpoint
POSThttps://api.vextorium.com/v1/mastodon-trending-posts?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need real-time engagement-ranked posts from a specific Mastodon instance, including full text and author details. Prefer it over scraping Mastodon's web UI or using the raw Mastodon API directly when you want a simple, paid-per-call abstraction without authentication overhead. Ideal for trend monitoring, content curation, and social listening on the Fediverse.
Side effects
- Invalid or unreachable Mastodon instance hostname returns an error or empty result
- Instance with no trending data (e.g. small servers with disabled trending) returns empty posts array
- Limit value out of acceptable range may be ignored or cause a validation error
- Rate limiting by the target Mastodon instance may result in stale or incomplete data
- Non-Mastodon ActivityPub servers passed as instance may fail silently
