• search

  Sofya

  Search the web for current information on any topic. Returns extracted page content, not just snippets. Best for factual lookups, specific questions, or when you need a list of sources. For open-ended questions that need synthesis across many sources, use the research tool instead. For news queries (current events, breaking news, politics, world events), set topic="news" to search news sources specifically. This returns recent articles with publication dates. Set include_answer=true to get an AI-synthesized answer alongside results (adds 5 credits). This is the sweet spot for most agent tasks, e.g. basic + include_answer = 8 credits, much cheaper than a full 25-credit research call. Returns: query, answer (if requested), results (array of {title, url, content, description, fetched, published_date}), search_depth, topic, elapsed_ms, credits_used, credits_remaining, altered_query. Args: query: The search query search_depth: "basic" (default) for extracted page content (3 credits), "snippets" for SERP snippets only without page fetching (1 credit) max_results: Number of results (default 10, max 20) include_answer: Generate an AI answer that synthesizes the search results (adds 5 credits) include_domains: Only include results from these domains (max 10) exclude_domains: Exclude results from these domains (max 10) topic: "general" for web search, "news" for news articles. use "news" for current events, breaking news, politics, or any time-sensitive query freshness: Filter by recency - "day", "week", "month", "year", or "YYYY-MM-DD:YYYY-MM-DD"

• search_reviews

  Search Cochrane systematic reviews via PubMed. Finds Cochrane Database of Systematic Reviews articles matching your query. Returns PubMed IDs, titles, and publication dates.

Args: query: Search terms for finding reviews (e.g. 'diabetes exercise', 'hypertension treatment', 'childhood vaccination safety'). limit: Maximum number of results to return (default 20, max 100).

  Agent402.Tools — pay-per-call web tools

  Keyword search over Agent402's 1432 pay-per-call web tools (live market data like stock-quote at $0.003, encoding, crypto, text, time, math, validation, unit conversions, network, browser, PDF, search, memory).

There is also an OpenAI-compatible LLM gateway at https://agent402.tools/v1 — flat per-call (chat nano $0.003, auto $0.01, embeddings $0.002), no API key: a funded wallet is the account.

Trigger on queries like: - "is BTC bullish or bearish?" - "what's the signal for ETH right now?" - "should I buy/sell XRP?" - "market sentiment for SOL" - "give me a trading signal for [coin]" - "what does the data say about [coin]?"

• firecrawl_map

  firecrawl-mcp

  Map a website to discover all indexed URLs on the site. **Best for:** Discovering URLs on a website before deciding what to scrape; finding specific sections or pages within a large site; locating the correct page when scrape returns empty or incomplete results. **Not recommended for:** When you already know which specific URL you need (use scrape); when you need the content of the pages (use scrape after mapping). **Common mistakes:** Using crawl to discover URLs instead of map; jumping straight to firecrawl_agent when scrape fails instead of using map first to find the right page. **IMPORTANT - Use map before agent:** If `firecrawl_scrape` returns empty, minimal, or irrelevant content, use `firecrawl_map` with the `search` parameter to find the specific page URL containing your target content. This is faster and cheaper than using `firecrawl_agent`. Only use the agent as a last resort after map+scrape fails. **Prompt Example:** "Find the webhook documentation page on this API docs site." **Usage Example (discover all URLs):** ```json { "name": "firecrawl_map", "arguments": { "url": "https://example.com" } } ``` **Usage Example (search for specific content - RECOMMENDED when scrape fails):** ```json { "name": "firecrawl_map", "arguments": { "url": "https://docs.example.com/api", "search": "webhook events" } } ``` **Returns:** Array of URLs found on the site, filtered by search query if provided.

• brave_local_search

  brave

  Brave Local Search API returns enriched information (address, phone, hours, rating) for location-search results. Access requires the Brave Search API Pro plan; currently US-only. Two-step flow: first call `brave_web_search` with `result_filter=locations` to obtain `locations.results[].id`, then pass them here. NOTE: This tool takes location IDs from a prior web-search response; if you have a free-text query, call `brave_web_search` first.
