Web tools

• web_search — Search the web via Brave Search API (default) or Perplexity Sonar (direct or via OpenRouter).
• web_fetch — HTTP fetch + readable extraction (HTML → markdown/text).

​

How it works

• web_search calls your configured provider and returns results.
  • Brave (default): returns structured results (title, URL, snippet).
  • Perplexity: returns AI-synthesized answers with citations from real-time web search.
• Results are cached by query for 15 minutes (configurable).
• web_fetch does a plain HTTP GET and extracts readable content (HTML → markdown/text). It does not execute JavaScript.
• web_fetch is enabled by default (unless explicitly disabled).

​

Choosing a search provider

{
  tools: {
    web: {
      search: {
        provider: "brave"  // or "perplexity"
      }
    }
  }
}

{
  tools: {
    web: {
      search: {
        provider: "perplexity",
        perplexity: {
          apiKey: "pplx-...",
          baseUrl: "https://api.perplexity.ai",
          model: "perplexity/sonar-pro"
        }
      }
    }
  }
}

​

Getting a Brave API key

1. Create a Brave Search API account at https://brave.com/search/api/
2. In the dashboard, choose the Data for Search plan (not “Data for AI”) and generate an API key.
3. Run clawdia configure --section web to store the key in config (recommended), or set BRAVE_API_KEY in your environment.

​

Where to set the key (recommended)

​

Using Perplexity (direct or via OpenRouter)

​

Getting an OpenRouter API key

1. Create an account at https://openrouter.ai/
2. Add credits (supports crypto, prepaid, or credit card)
3. Generate an API key in your account settings

​

Setting up Perplexity search

{
  tools: {
    web: {
      search: {
        enabled: true,
        provider: "perplexity",
        perplexity: {
          // API key (optional if OPENROUTER_API_KEY or PERPLEXITY_API_KEY is set)
          apiKey: "sk-or-v1-...",
          // Base URL (key-aware default if omitted)
          baseUrl: "https://openrouter.ai/api/v1",
          // Model (defaults to perplexity/sonar-pro)
          model: "perplexity/sonar-pro"
        }
      }
    }
  }
}

• PERPLEXITY_API_KEY or pplx-... → https://api.perplexity.ai
• OPENROUTER_API_KEY or sk-or-... → https://openrouter.ai/api/v1
• Unknown key formats → OpenRouter (safe fallback)

​

Available Perplexity models

​

web_search

​

Requirements

• tools.web.search.enabled must not be false (default: enabled)
• API key for your chosen provider:
  • Brave: BRAVE_API_KEY or tools.web.search.apiKey
  • Perplexity: OPENROUTER_API_KEY, PERPLEXITY_API_KEY, or tools.web.search.perplexity.apiKey

​

Config

{
  tools: {
    web: {
      search: {
        enabled: true,
        apiKey: "BRAVE_API_KEY_HERE", // optional if BRAVE_API_KEY is set
        maxResults: 5,
        timeoutSeconds: 30,
        cacheTtlMinutes: 15
      }
    }
  }
}

​

Tool parameters

• query (required)
• count (1–10; default from config)
• country (optional): 2-letter country code for region-specific results (e.g., “DE”, “US”, “ALL”). If omitted, Brave chooses its default region.
• search_lang (optional): ISO language code for search results (e.g., “de”, “en”, “fr”)
• ui_lang (optional): ISO language code for UI elements
• freshness (optional, Brave only): filter by discovery time (pd, pw, pm, py, or YYYY-MM-DDtoYYYY-MM-DD)

// German-specific search
await web_search({
  query: "TV online schauen",
  count: 10,
  country: "DE",
  search_lang: "de"
});

// French search with French UI
await web_search({
  query: "actualités",
  country: "FR",
  search_lang: "fr",
  ui_lang: "fr"
});

// Recent results (past week)
await web_search({
  query: "TMBG interview",
  freshness: "pw"
});

​

web_fetch

​

Requirements

• tools.web.fetch.enabled must not be false (default: enabled)
• Optional Firecrawl fallback: set tools.web.fetch.firecrawl.apiKey or FIRECRAWL_API_KEY.

​

Config

{
  tools: {
    web: {
      fetch: {
        enabled: true,
        maxChars: 50000,
        timeoutSeconds: 30,
        cacheTtlMinutes: 15,
        maxRedirects: 3,
        userAgent: "Mozilla/5.0 (Macintosh; Intel Mac OS X 14_7_2) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/122.0.0.0 Safari/537.36",
        readability: true,
        firecrawl: {
          enabled: true,
          apiKey: "FIRECRAWL_API_KEY_HERE", // optional if FIRECRAWL_API_KEY is set
          baseUrl: "https://api.firecrawl.dev",
          onlyMainContent: true,
          maxAgeMs: 86400000, // ms (1 day)
          timeoutSeconds: 60
        }
      }
    }
  }
}

​

Tool parameters

• url (required, http/https only)
• extractMode (markdown | text)
• maxChars (truncate long pages)

• web_fetch uses Readability (main-content extraction) first, then Firecrawl (if configured). If both fail, the tool returns an error.
• Firecrawl requests use bot-circumvention mode and cache results by default.
• web_fetch sends a Chrome-like User-Agent and Accept-Language by default; override userAgent if needed.
• web_fetch blocks private/internal hostnames and re-checks redirects (limit with maxRedirects).
• web_fetch is best-effort extraction; some sites will need the browser tool.
• See Firecrawl for key setup and service details.
• Responses are cached (default 15 minutes) to reduce repeated fetches.
• If you use tool profiles/allowlists, add web_search/web_fetch or group:web.
• If the Brave key is missing, web_search returns a short setup hint with a docs link.
