{"name":"research-topic-scan","description":"Research scan API for a multi source search sweep: send one query and get back web results, recent news, an encyclopedia summary, academic papers, developer/Hacker News chatter, and X/Twitter chatter in a single call. Built for agent-led research, topic research, and due-diligence sweeps where a caller would otherwise fire off six separate lookups and merge them by hand. Composite: one call runs web-search + news-search + wikipedia-search + arxiv-search + hn-search + x-search in parallel, dedupes hits by URL, and tags each result with its source. Only web-search is required; news/wikipedia/arxiv/hn/x-search degrade the response instead of failing the call if their upstream is slow or down (x-search also needs a configured X bearer token). Use it as a research scan API, a topic research tool, or a web-news-papers-tweets aggregator for agents scoping a subject before they write or decide.","price":"$0.06","method":"POST","input_schema":{"properties":{"query":{"type":"string","description":"The topic or question to research, e.g. 'stablecoin regulation 2026'.
