{"name":"research-radar","description":"Re-runnable topic monitor: the latest arXiv papers sorted by most-recently-updated, recent (week-scoped) web coverage, and a structured research brief, in one call. Composite: one call runs arxiv-search + search in parallel (both required together — the call only fails if both fail) plus research-brief as an optional third leg. Distinct from patent-landscape-brief, which sorts arXiv by relevance and frames the same two search legs around prior art rather than what's newly published. Use it as a recurring topic-monitoring feed for agents tracking a fast-moving research area.","price":"$0.05","method":"POST","input_schema":{"properties":{"topic":{"type":"string","description":"Research topic to monitor, e.g. 'mixture of experts routing'.
