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
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.
Configure
```bash
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.
Use it
The agent can now call `web_search`:
```javascript
await web_search({ query: "OpenClaw plugin SDK" });
```
For X posts, use:
```javascript
await x_search({ query: "dinner recipes" });
```
Choosing a provider
- Brave Search — Structured results with snippets. Supports
llm-contextmode, country/language filters. Free tier available. - Codex Hosted Search — AI-synthesized grounded answers through your Codex app-server account.
- DuckDuckGo — Key-free provider. 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_searchandfirecrawl_scrapefor 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.
- Parallel — Paid Parallel Search API (
PARALLEL_API_KEY); higher rate limits and objective tuning. - Parallel Search (Free) — Key-free opt-in. Parallel's free Search MCP, with LLM-optimized dense excerpts and no API key.
- 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_extractfor 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
The Codex app-server runtime uses Codex's hosted web_search tool automatically when web search is enabled and no managed provider is selected. Native hosted search and OpenClaw's managed web_search dynamic tool are mutually exclusive, so managed search cannot bypass native domain restrictions. OpenClaw uses the managed tool when hosted search is unavailable, explicitly disabled, or replaced by a selected managed provider. OpenClaw keeps Codex's standalone web.run extension disabled because production app-server traffic rejects its user-defined web namespace.
- Configure native search under
tools.web.search.openaiCodex - Set
tools.web.search.provider: "codex"to provision Codex Hosted Search as the managedweb_searchprovider for any parent model. Each call runs a bounded ephemeral Codex app-server turn and fails if Codex does not emit a hostedwebSearchitem. mode: "cached"is the default preference, but Codex resolves it to live external access for unrestricted app-server turns; set"live"to request live access explicitly- Set
tools.web.search.providerto a managed provider such asbraveto use OpenClaw's managedweb_searchinstead - Set
tools.web.search.openaiCodex.enabled: falseto opt out of Codex-hosted search; other managed providers remain available - Restricting the Codex native tool surface also keeps managed
web_searchavailable - When
allowedDomainsis set, automatic managed fallback fails closed if hosted search is unavailable so the native allowlist cannot be bypassed - Tool-disabled LLM-only runs disable both native and managed search
tools.web.search.enabled: falsedisables both managed and native search
Persistent effective Codex search-policy changes start a fresh bound thread so an already loaded app-server thread cannot keep stale hosted-search access. Transient per-turn restrictions use a temporary restricted thread and preserve the existing binding for later resume.
Direct OpenAI ChatGPT Responses traffic can also use OpenAI's hosted web_search tool. That separate path remains opt-in through tools.web.search.openaiCodex.enabled: true and only applies to eligible openai/* models using api: "openai-chatgpt-responses".
{
tools: {
web: {
search: {
enabled: true,
// Optional: use Codex Hosted Search from non-Codex parent models too.
provider: "codex",
openaiCodex: {
enabled: true,
mode: "cached",
allowedDomains: ["example.com"],
contextSize: "high",
userLocation: {
country: "US",
city: "New York",
timezone: "America/New_York",
},
},
},
},
},
}For runtimes and providers that do not support native Codex search, Codex can use the managed web_search fallback through OpenClaw's dynamic tool namespace. Use an explicit managed provider when you need OpenClaw's provider-specific network controls instead of Codex-hosted search.
Selecting provider: "codex" enables the bundled codex plugin and uses the same tools.web.search.openaiCodex restrictions shown above. Authenticate the Codex app-server first with openclaw models auth login --provider openai. The parent agent can use any model or runtime; only the bounded search worker runs through Codex.
Network safety
Managed HTTP 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. Codex Hosted Search is the exception: its bounded worker delegates network access to Codex app-server's hosted web_search tool.
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:
- Brave --
BRAVE_API_KEYorplugins.entries.brave.config.webSearch.apiKey(order 10) - MiniMax Search --
MINIMAX_CODE_PLAN_KEY/MINIMAX_CODING_API_KEY/MINIMAX_OAUTH_TOKEN/MINIMAX_API_KEYorplugins.entries.minimax.config.webSearch.apiKey(order 15) - Gemini --
plugins.entries.google.config.webSearch.apiKey,GEMINI_API_KEY, ormodels.providers.google.apiKey(order 20) - Grok -- xAI OAuth,
XAI_API_KEY, orplugins.entries.xai.config.webSearch.apiKey(order 30) - Kimi --
KIMI_API_KEY/MOONSHOT_API_KEYorplugins.entries.moonshot.config.webSearch.apiKey(order 40) - Perplexity --
PERPLEXITY_API_KEY/OPENROUTER_API_KEYorplugins.entries.perplexity.config.webSearch.apiKey(order 50) - Firecrawl --
FIRECRAWL_API_KEYorplugins.entries.firecrawl.config.webSearch.apiKey(order 60) - Exa --
EXA_API_KEYorplugins.entries.exa.config.webSearch.apiKey; optionalplugins.entries.exa.config.webSearch.baseUrloverrides the Exa endpoint (order 65) - Tavily --
TAVILY_API_KEYorplugins.entries.tavily.config.webSearch.apiKey(order 70) - Parallel -- paid Parallel Search API via
PARALLEL_API_KEYorplugins.entries.parallel.config.webSearch.apiKey; optionalplugins.entries.parallel.config.webSearch.baseUrloverrides the endpoint (order 75)
Configured endpoint providers after that:
- SearXNG --
SEARXNG_BASE_URLorplugins.entries.searxng.config.webSearch.baseUrl(order 200)
Key-free providers such as Parallel Search (Free), DuckDuckGo, Ollama Web Search, and Codex Hosted Search are available only when you select them explicitly with tools.web.search.provider or through openclaw configure --section web. OpenClaw does not send managed web_search queries to a key-free provider just because no API-backed provider is configured.
OpenAI Responses models are an exception: while tools.web.search.provider is unset, they use OpenAI's native web search instead of the managed providers above. Set tools.web.search.provider to parallel-free (or another provider) to route them through the managed path.
Note
All provider key fields support SecretRef objects. Plugin-scoped SecretRefs under plugins.entries.<plugin>.config.webSearch.apiKey are resolved for the bundled API-backed web search providers, including Brave, Exa, Firecrawl, Gemini, Grok, Kimi, MiniMax, Parallel, Perplexity, and Tavily, whether the provider is picked explicitly via tools.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_fetchcan use installed plugin providers that declarecontracts.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/v1orhttps://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 file
Run `openclaw configure --section web` or set the key directly:
```json5
{
plugins: {
entries: {
brave: {
config: {
webSearch: {
apiKey: "YOUR_KEY", // pragma: allowlist secret
},
},
},
},
},
}
```
Environment variable
Set the provider env var in the Gateway process environment:
```bash
export BRAVE_API_KEY="YOUR_KEY"
```
For a gateway install, put it in `~/.openclaw/.env`.
See [Env vars](/en/help/faq#env-vars-and-env-loading).
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)
