| Tool | Description | Behaviour |
|---|---|---|
| get_cluster | Get one news event in detail. A cluster is a single real-world event assembled from many outlets covering the same happening and deduplicated into one item, so you get one event rather than 20 near-duplicate headlines. Returns its summary, a significance score (1 to 10, where 8 and above is exceptional), a source count, the situation it belongs to if any, and its underlying source articles with links. It returns up to 100 representative articles, one per source; `sources` and `articles_total` are the full count, and `articles_truncated` says whether the list was cut. Use this when the user wants the specifics of one event. Get a cluster id from search_situations, get_situation_timeline, or a clstr.news URL. Cite the returned URLs. (Requires sign-in, or a free API key: https://clstr.news/developers) | Read-only |
| get_situation_timeline | Get the full chronological timeline of one situation. A situation is an ongoing storyline (story arc) that groups related news events over time; it carries a maintained summary plus every event in order, so you see not just what happened but how it developed. Each event is a cluster (one happening assembled from many outlets and deduplicated) with its date, a significance score (1 to 10, where 8 and above is exceptional), a source count, and a canonical clstr.news link. Use this to brief on a story's history or answer 'how did this develop'. Get a situation id from search_situations or get_top_situations, or from a clstr.news URL. An id that was retired when two situations merged resolves to the successor, flagged with merged_into_shown. Cite the returned URLs. | Read-only |
| get_top_situations | List the situations developing right now, ranked by relevance: a blend of significance, how many outlets are covering it, and how recently it moved. So a lower significance score can rank above a higher one, and that ordering is intentional; do not re-sort. A situation is an ongoing storyline that groups related news events over time and carries a maintained summary and a source count (how many outlets are behind it). Optionally filter by category, by country, and by time window (24h, 7d, or 30d), and switch the ordering to newest activity first with sort. Use this to answer 'what is going on in the world', 'what is happening in <category>' or 'what is happening in <country>' when there is no specific topic yet, then open any result with get_situation_timeline. When there are more, the result ends with a cursor to page further. Pass summary: "full" to get each situation's maintained summary in full, instead of a one-line preview, without a follow-up call per result; full summaries in a list are not enabled for every account, so read summary_mode in the result to see what you got, and use get_situation_timeline for one situation's summary in full. Cite the returned URLs. | Read-only |
| search_situations | Search the news by topic to find matching situations and events. A situation is an ongoing storyline (story arc) that groups related events over time; an event, called a cluster, is one happening assembled from many outlets and deduplicated into a single item, so you get one event rather than 20 near-duplicate headlines. Results come back grouped under their situations, each with a one-line summary, a significance score (1 to 10, where 8 and above is exceptional), a source count (how many outlets are covering it), and a canonical clstr.news link. Use this to answer 'what is happening around X' for a topic, company, country, or event. Then open a result with get_situation_timeline for the full history, or get_cluster for one event's detail. Results are relevance ordered and bounded to the top matches: when there are more, the result ends with a cursor to pass back, and each page counts as one search against your cap. Pass summary: "full" to read each match's summary untruncated instead of one line. Cite the returned URLs. (Requires sign-in, or a free API key: https://clstr.news/developers) | Read-only |
