OpenClaw supports Grok as a web_search provider, using xAI web-grounded responses to produce AI-synthesized answers backed by live search results with citations. The same XAI_API_KEY can also power the built-in x_search tool for X (formerly Twitter) post search. If you store the key under plugins.entries.xai.config.webSearch.apiKey, OpenClaw now reuses it as a fallback for the bundled xAI model provider too. For post-level X metrics such as reposts, replies, bookmarks, or views, prefer x_search with the exact post URL or status ID instead of a broad search query.

​
Onboarding and configure

If you choose Grok during:
  • openclaw onboard
  • openclaw configure --section web
OpenClaw can show a separate follow-up step to enable x_search with the same XAI_API_KEY. That follow-up:
  • only appears after you choose Grok for web_search
  • is not a separate top-level web-search provider choice
  • can optionally set the x_search model during the same flow
If you skip it, you can enable or change x_search later in config.

​
Get an API key

1

Create a key

Get an API key from xAI.
2

Store the key

Set XAI_API_KEY in the Gateway environment, or configure via:
openclaw configure --section web

​
Config

{
  plugins: {
    entries: {
      xai: {
        config: {
          webSearch: {
            apiKey: "xai-...", // optional if XAI_API_KEY is set
            baseUrl: "https://api.x.ai/v1", // optional Responses API proxy/base URL override
          },
        },
      },
    },
  },
  tools: {
    web: {
      search: {
        provider: "grok",
      },
    },
  },
}
Environment alternative: set XAI_API_KEY in the Gateway environment. For a gateway install, put it in ~/.openclaw/.env.

​
How it works

Grok uses xAI web-grounded responses to synthesize answers with inline citations, similar to Gemini’s Google Search grounding approach.

​
Supported parameters

Grok search supports query. count is accepted for shared web_search compatibility, but Grok still returns one synthesized answer with citations rather than an N-result list. Provider-specific filters are not currently supported. Grok uses a provider-specific 60 second default timeout because xAI Responses web-grounded searches can run longer than the shared web_search default. Set tools.web.search.timeoutSeconds to override it.

​
Base URL overrides

Set plugins.entries.xai.config.webSearch.baseUrl when Grok web search should route through an operator proxy or xAI-compatible Responses endpoint. OpenClaw posts to <baseUrl>/responses after trimming trailing slashes. x_search uses the same webSearch.baseUrl fallback unless plugins.entries.xai.config.xSearch.baseUrl is set.
