Spredfast Experiences Stream API
Curated social stream data powering Khoros Marketing Experiences visualisations — 48 operations for stream items, leaderboards, stream meta, topic and hashtag counts, and volume comparison. Served from api.massrelevance.com, the host inherited from Mass Relevance, which Spredfast acquired in 2013 and rebranded as Spredfast Experiences; the provider's own reference page states "Experiences is a Khoros Marketing product" and that access requires accepting the Spredfast Experiences API usage agreement. PROBED 2026-08-13: that host returns HTTP 502 on every path including /, while the contract remains published on the current developer center.
