The live X trending-topics feed and discussion signals from one REST endpoint. Since X moved its API behind paid tiers, getting this data programmatically means paying or scraping. Trends API serves it as JSON with one key.

}X is where narratives form in public before they move to search and news. The trending-topics feed is the fastest read on what the platform is talking about right now, and it has been effectively locked behind X's paid API tiers since 2023.
Trends API gives you that feed back as clean JSON, normalized so you can line it up against Google Trends, Reddit and news volume in the same units. One key, one endpoint, no X developer account, no per-tweet pricing.
