Use `firecrawl_search` when additional web sources are needed; on an authenticated session, `firecrawl_map` lists a site's URLs and `firecrawl_crawl` collects a set of pages.\n\nFirecrawl may serve recently indexed content; set `maxAge: 0` for a live fetch or a smaller `maxAge` to bound staleness.

"description": "\nSearch web, news, or image sources and return ranked results with query-relevant highlights. Use it for current information, or to list businesses, people, products, jobs or events with websites, prices or contacts. Each web result is a title, URL, and description; use `firecrawl_scrape` on a result URL when the excerpt is not enough.\n\nAuthenticated search also returns matching Alexandria data providers in data.tools (companies, people, jobs, finance and filings, public records and government spending, real estate, places and restaurants, retail and prices, package registries and developer data, news, research, and more). Prefer a provider over scraping pages when the task needs the same fields across several entities, exact figures or timestamps, provenance, or many records; use web results when they already answer the question. Authenticated searches always add alexandria to the sources, so sources: [\"web\"] also returns providers; domainTools: false turns off website-matched tools only.\n\nOn an authenticated session, tool matches describe available capabilities; `firecrawl_find_tools` returns their contracts and `firecrawl_scrape` with an `alexandria` body executes a selected capability. Keyless sessions get no Alexandria matches in data.tools.\n\nFor a programming question, add `categories: [\"developer\"]`; its hits return in `data.web` with `category: \"developer\"`. For a legal or regulatory question, `categories: [\"gov\"]` returns hits in `data.web` with `category: \"gov\"` and cannot be combined with other categories; authenticated sessions also have `firecrawl_gov_search` as the dedicated tool. Verify gov results' issuer, jurisdiction, status, and version before citing current law. `categories: [\"research\"]` restricts web results to research-affiliated websites; the `firecrawl_research_*` tools are a separate surface over paper abstracts and full text (PubMed, bioRxiv, medRxiv, arXiv).
