search_worlds
Search worlds
Browse and search published worlds. Sort by newest, liked, or trending. The days filter accepts 1, 7 (API default), or 30 UTC calendar days including today, or all for any sort. Newest filters publication date unless days=all or creator is specified. Liked ranks period likes, or lifetime likes when days=all. Trending ranks period activity, or lifetime plays and likes when days=all, with publication-age decay in both cases. Older worlds may appear in activity rankings. The Explore website defaults to liked/all; API defaults remain newest/7. Search text can include exact #tags; custom tags are supported without a fixed vocabulary. Liked and trending require the community flag. Follow nextCursor with unchanged filters until null. Drafts and offline worlds are excluded. Public; no authentication is required.
