web_search
Read-onlyIdempotent
Search the web to retrieve relevant page titles and snippets without reading full content. Filter results by domain, time range, or trusted sources for targeted research.
Instructions
Search the web and get a list of relevant pages with titles and snippets — without reading the full page content. Narrow results to one domain with the site parameter, or apply a search lens to restrict to trusted sites in a field (see the lens parameter for the full list). Use search_and_scrape if you need full page text, news_search for current events, or academic_search for research papers. Results stay fresh for 30 minutes; use time_range to get more recent results.
Input Schema
TableJSON Schema
| Name | Required | Description | Default |
|---|---|---|---|
| lens | No | Focus your search on trusted sites in a specific field: docs, academic, academic-extended, clinical, security, journalism, programming, devops, news, tech, legal, medical, finance, science, government. Only one lens can be active at a time (overrides the site parameter). | |
| safe | No | SafeSearch level: off, medium (default), or high. | |
| site | No | Restrict to a single domain (e.g. stackoverflow.com). Cannot combine with lens. | |
| claim | No | Optional claim to evaluate against each result's snippet. When set, each result gains a claimSignal (the most claim-relevant snippet sentence) to help triage which links to read; for full-text evidence use search_and_scrape with claim. Evidence only — the server never decides supports/contradicts. | |
| query | Yes | The search query text (1-500 chars). Be specific with key terms and qualifiers for better results.,required | |
| country | No | Restrict to a country using ISO 3166-1 alpha-2 code (e.g. US, GB). | |
| language | No | Filter by language using ISO 639-1 code (e.g. en, fr, de). | |
| provider | No | Choose which search engine to use for this query: google, brave, serper, searxng, searchapi, duckduckgo, tavily, exa, hackernews. Leave empty to use the default. Returns an error if the chosen provider isn't set up. | |
| sessionId | No | Link results to a sequential_search session. Sources are automatically recorded in the session for recovery after context loss. | |
| time_range | No | Restrict to a time period: day, week, month, or year. Omit for all-time results. | |
| exact_terms | No | Phrase that must appear verbatim in results. | |
| num_results | No | Number of results to return (1-10). Default: 5. Higher values increase latency. | |
| exclude_terms | No | Terms to exclude from results (space-separated). |
