Web search

The web_search tool searches the web using your configured provider and returns results. Results are cached by query for 15 minutes (configurable).

OpenClaw also includes x_search for X (formerly Twitter) posts and web_fetch for lightweight URL fetching. In this phase, web_fetch stays local while web_search and x_search can use xAI Responses under the hood.

Info

web_search is a lightweight HTTP tool, not browser automation. For JS-heavy sites or logins, use the Web Browser. For fetching a specific URL, use Web Fetch.

Quick start

1. Choose a provider

   Pick a provider and complete any required setup. Some providers are key-free, while others use API keys. See the provider pages below for details.

2. Configure

   openclaw configure --section web

   This stores the provider and any needed credential. You can also set an env var (for example BRAVE_API_KEY) and skip this step for API-backed providers.

3. Use it

   The agent can now call web_search:

   await web_search({ query: "OpenClaw plugin SDK" });

   For X posts, use:

   await x_search({ query: "dinner recipes" });

Choosing a provider

Brave Search

Structured results with snippets. Supports llm-context mode, country/language filters. Free tier available.

DuckDuckGo

Key-free fallback. No API key needed. Unofficial HTML-based integration.

Exa

Neural + keyword search with content extraction (highlights, text, summaries).

Firecrawl

Structured results. Best paired with firecrawl_search and firecrawl_scrape for deep extraction.

Gemini

AI-synthesized answers with citations via Google Search grounding.

Grok

AI-synthesized answers with citations via xAI web grounding.

Kimi

AI-synthesized answers with citations via Moonshot web search; ungrounded chat fallbacks fail explicitly.

MiniMax Search

Structured results via the MiniMax Token Plan search API.

Ollama Web Search

Search via a signed-in local Ollama host or the hosted Ollama API.

Perplexity

Structured results with content extraction controls and domain filtering.

SearXNG

Self-hosted meta-search. No API key needed. Aggregates Google, Bing, DuckDuckGo, and more.

Tavily

Structured results with search depth, topic filtering, and tavily_extract for URL extraction.

Auto-detection

Native OpenAI web search

Direct OpenAI Responses models use OpenAI’s hosted web_search tool automatically when OpenClaw web search is enabled and no managed provider is pinned. This is provider-owned behavior in the bundled OpenAI plugin and only applies to native OpenAI API traffic, not OpenAI-compatible proxy base URLs or Azure routes. Set tools.web.search.provider to another provider such as brave to keep the managed web_search tool for OpenAI models, or set tools.web.search.enabled: false to disable both managed search and native OpenAI search.

Native Codex web search

Codex-capable models can optionally use the provider-native Responses web_search tool instead of OpenClaw’s managed web_search function.

• Configure it under tools.web.search.openaiCodex
• It only activates for Codex-capable models (openai-codex/* or providers using api: "openai-codex-responses")
• Managed web_search still applies to non-Codex models
• mode: "cached" is the default and recommended setting
• tools.web.search.enabled: false disables both managed and native search

{
  tools: {
    web: {
      search: {
        enabled: true,
        openaiCodex: {
          enabled: true,
          mode: "cached",
          allowedDomains: ["example.com"],
          contextSize: "high",
          userLocation: {
            country: "US",
            city: "New York",
            timezone: "America/New_York",
          },
        },
      },
    },
  },
}

If native Codex search is enabled but the current model is not Codex-capable, OpenClaw keeps the normal managed web_search behavior.

Network safety

Managed web_search provider calls use OpenClaw’s guarded fetch path. For trusted provider API hosts, OpenClaw allows Surge, Clash, and sing-box fake-IP DNS answers in 198.18.0.0/15 and fc00::/7 only for that provider hostname. Other private, loopback, link-local, and metadata destinations remain blocked.

This automatic allowance does not apply to arbitrary web_fetch URLs. For web_fetch, enable tools.web.fetch.ssrfPolicy.allowRfc2544BenchmarkRange and tools.web.fetch.ssrfPolicy.allowIpv6UniqueLocalRange explicitly only when your trusted proxy owns those synthetic ranges.

Setting up web search

Provider lists in docs and setup flows are alphabetical. Auto-detection keeps a separate precedence order.

If no provider is set, OpenClaw checks providers in this order and uses the first one that is ready:

API-backed providers first:

1. Brave — BRAVE_API_KEY or plugins.entries.brave.config.webSearch.apiKey (order 10)
2. MiniMax Search — MINIMAX_CODE_PLAN_KEY / MINIMAX_CODING_API_KEY / MINIMAX_OAUTH_TOKEN / MINIMAX_API_KEY or plugins.entries.minimax.config.webSearch.apiKey (order 15)
3. Gemini — plugins.entries.google.config.webSearch.apiKey, GEMINI_API_KEY, or models.providers.google.apiKey (order 20)
4. Grok — xAI OAuth, XAI_API_KEY, or plugins.entries.xai.config.webSearch.apiKey (order 30)
5. Kimi — KIMI_API_KEY / MOONSHOT_API_KEY or plugins.entries.moonshot.config.webSearch.apiKey (order 40)
6. Perplexity — PERPLEXITY_API_KEY / OPENROUTER_API_KEY or plugins.entries.perplexity.config.webSearch.apiKey (order 50)
7. Firecrawl — FIRECRAWL_API_KEY or plugins.entries.firecrawl.config.webSearch.apiKey (order 60)
8. Exa — EXA_API_KEY or plugins.entries.exa.config.webSearch.apiKey; optional plugins.entries.exa.config.webSearch.baseUrl overrides the Exa endpoint (order 65)
9. Tavily — TAVILY_API_KEY or plugins.entries.tavily.config.webSearch.apiKey (order 70)

Key-free fallbacks after that:

10. DuckDuckGo — key-free HTML fallback with no account or API key (order 100)
11. Ollama Web Search — key-free fallback via your configured local Ollama host when it is reachable and signed in with ollama signin; can reuse Ollama provider bearer auth when the host needs it, and can call direct https://ollama.com search when configured with OLLAMA_API_KEY (order 110)
12. SearXNG — SEARXNG_BASE_URL or plugins.entries.searxng.config.webSearch.baseUrl (order 200)

If no provider is detected, it falls back to Brave (you will get a missing-key error prompting you to configure one).

Note

All provider key fields support SecretRef objects. Plugin-scoped SecretRefs under `plugins.entries.

.config.webSearch.apiKeyare resolved for the bundled API-backed web search providers, including Brave, Exa, Firecrawl, Gemini, Grok, Kimi, MiniMax, Perplexity, and Tavily, whether the provider is picked explicitly viatools.web.search.provider` or selected through auto-detect. In auto-detect mode, OpenClaw resolves only the selected provider key — non-selected SecretRefs stay inactive, so you can keep multiple providers configured without paying resolution cost for the ones you are not using.

Config

{
  tools: {
    web: {
      search: {
        enabled: true, // default: true
        provider: "brave", // or omit for auto-detection
        maxResults: 5,
        timeoutSeconds: 30,
        cacheTtlMinutes: 15,
      },
    },
  },
}

Provider-specific config (API keys, base URLs, modes) lives under plugins.entries.<plugin>.config.webSearch.*. Gemini can also reuse models.providers.google.apiKey and models.providers.google.baseUrl as lower-priority fallbacks after its dedicated web-search config and GEMINI_API_KEY. See the provider pages for examples. Grok can also reuse an xAI OAuth auth profile from openclaw models auth login --provider xai --method oauth; API-key config remains the fallback.

tools.web.search.provider is validated against the web-search provider ids declared by bundled and installed plugin manifests. A typo such as "brvae" fails config validation instead of silently falling back to auto-detection. If a configured provider only has stale plugin evidence, such as a leftover plugins.entries.<plugin> block after uninstalling a third-party plugin, OpenClaw keeps startup resilient and reports a warning so you can reinstall the plugin or run openclaw doctor --fix to clean up the stale config.

web_fetch fallback provider selection is separate:

• choose it with tools.web.fetch.provider
• or omit that field and let OpenClaw auto-detect the first ready web-fetch provider from available credentials
• non-sandboxed web_fetch can use installed plugin providers that declare contracts.webFetchProviders; sandboxed fetches stay bundled-only
• today the bundled web-fetch provider is Firecrawl, configured under plugins.entries.firecrawl.config.webFetch.*

When you choose Kimi during openclaw onboard or openclaw configure --section web, OpenClaw can also ask for:

• the Moonshot API region (https://api.moonshot.ai/v1 or https://api.moonshot.cn/v1)
• the default Kimi web-search model (defaults to kimi-k2.6)

For x_search, configure plugins.entries.xai.config.xSearch.*. It uses the same xAI auth profile as chat, or the XAI_API_KEY / plugin web-search credential used by Grok web search. Legacy tools.web.x_search.* config is auto-migrated by openclaw doctor --fix. When you choose Grok during openclaw onboard or openclaw configure --section web, OpenClaw can also offer optional x_search setup with the same credential. This is a separate follow-up step inside the Grok path, not a separate top-level web-search provider choice. If you pick another provider, OpenClaw does not show the x_search prompt.

Storing API keys

Config fileEnvironment variable

Run openclaw configure --section web or set the key directly:

{
  plugins: {
    entries: {
      brave: {
        config: {
          webSearch: {
            apiKey: "YOUR_KEY", // pragma: allowlist secret
          },
        },
      },
    },
  },
}

Set the provider env var in the Gateway process environment:

export BRAVE_API_KEY="YOUR_KEY"

For a gateway install, put it in ~/.openclaw/.env. See Env vars.

Tool parameters

Parameter	Description
query	Search query (required)
count	Results to return (1-10, default: 5)
country	2-letter ISO country code (e.g. “US”, “DE”)
language	ISO 639-1 language code (e.g. “en”, “de”)
search_lang	Search-language code (Brave only)
freshness	Time filter: day, week, month, or year
date_after	Results after this date (YYYY-MM-DD)
date_before	Results before this date (YYYY-MM-DD)
ui_lang	UI language code (Brave only)
domain_filter	Domain allowlist/denylist array (Perplexity only)
max_tokens	Total content budget, default 25000 (Perplexity only)
max_tokens_per_page	Per-page token limit, default 2048 (Perplexity only)

Warning

Not all parameters work with all providers. Brave llm-context mode rejects ui_lang; date_before also needs date_after because Brave custom freshness ranges require both start and end dates. Gemini, Grok, and Kimi return one synthesized answer with citations. They accept count for shared-tool compatibility, but it does not change the grounded answer shape. Gemini supports freshness, date_after, and date_before by converting them to Google Search grounding time ranges. Perplexity behaves the same way when you use the Sonar/OpenRouter compatibility path (plugins.entries.perplexity.config.webSearch.baseUrl / model or OPENROUTER_API_KEY). SearXNG accepts http:// only for trusted private-network or loopback hosts; public SearXNG endpoints must use https://. Firecrawl and Tavily only support query and count through web_search — use their dedicated tools for advanced options.

x_search

x_search queries X (formerly Twitter) posts using xAI and returns AI-synthesized answers with citations. It accepts natural-language queries and optional structured filters. OpenClaw only enables the built-in xAI x_search tool on the request that serves this tool call.

Note

xAI documents x_search as supporting keyword search, semantic search, user search, and thread fetch. For per-post engagement stats such as reposts, replies, bookmarks, or views, prefer a targeted lookup for the exact post URL or status ID. Broad keyword searches may find the right post but return less complete per-post metadata. A good pattern is: locate the post first, then run a second x_search query focused on that exact post.

x_search config

{
  plugins: {
    entries: {
      xai: {
        config: {
          xSearch: {
            enabled: true,
            model: "grok-4-1-fast-non-reasoning",
            baseUrl: "https://api.x.ai/v1", // optional, overrides webSearch.baseUrl
            inlineCitations: false,
            maxTurns: 2,
            timeoutSeconds: 30,
            cacheTtlMinutes: 15,
          },
          webSearch: {
            apiKey: "xai-...", // optional if an xAI auth profile or XAI_API_KEY is set
            baseUrl: "https://api.x.ai/v1", // optional shared xAI Responses base URL
          },
        },
      },
    },
  },
}

x_search posts to <baseUrl>/responses when plugins.entries.xai.config.xSearch.baseUrl is set. If that field is omitted, it falls back to plugins.entries.xai.config.webSearch.baseUrl, then the legacy tools.web.search.grok.baseUrl, and finally the public xAI endpoint.

x_search parameters

Parameter	Description
query	Search query (required)
allowed_x_handles	Restrict results to specific X handles
excluded_x_handles	Exclude specific X handles
from_date	Only include posts on or after this date (YYYY-MM-DD)
to_date	Only include posts on or before this date (YYYY-MM-DD)
enable_image_understanding	Let xAI inspect images attached to matching posts
enable_video_understanding	Let xAI inspect videos attached to matching posts

x_search example

await x_search({
  query: "dinner recipes",
  allowed_x_handles: ["nytfood"],
  from_date: "2026-03-01",
});

// Per-post stats: use the exact status URL or status ID when possible
await x_search({
  query: "https://x.com/huntharo/status/1905678901234567890",
});

Examples

// Basic search
await web_search({ query: "OpenClaw plugin SDK" });

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

// Recent results (past week)
await web_search({ query: "AI developments", freshness: "week" });

// Date range
await web_search({
  query: "climate research",
  date_after: "2024-01-01",
  date_before: "2024-06-30",
});

// Domain filtering (Perplexity only)
await web_search({
  query: "product reviews",
  domain_filter: ["-reddit.com", "-pinterest.com"],
});

Tool profiles

If you use tool profiles or allowlists, add web_search, x_search, or group:web:

{
  tools: {
    allow: ["web_search", "x_search"],
    // or: allow: ["group:web"]  (includes web_search, x_search, and web_fetch)
  },
}
