Gemini Search

OpenClaw supports Gemini models with built-in Google Search grounding, which returns AI-synthesized answers backed by live Google Search results with citations.

Get an API key

1

Create a key

Go to Google AI Studio and create an API key.
2

Store the key

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

​
Config

{
  plugins: {
    entries: {
      google: {
        config: {
          webSearch: {
            apiKey: "AIza...", // optional if GEMINI_API_KEY is set
            model: "gemini-2.5-flash", // default
          },
        },
      },
    },
  },
  tools: {
    web: {
      search: {
        provider: "gemini",
      },
    },
  },
}
Environment alternative: set GEMINI_API_KEY in the Gateway environment. For a gateway install, put it in ~/.openclaw/.env.

​
How it works

Unlike traditional search providers that return a list of links and snippets, Gemini uses Google Search grounding to produce AI-synthesized answers with inline citations. The results include both the synthesized answer and the source URLs.
  • Citation URLs from Gemini grounding are automatically resolved from Google redirect URLs to direct URLs.
  • Redirect resolution uses the SSRF guard path (HEAD + redirect checks + http/https validation) before returning the final citation URL.
  • Redirect resolution uses strict SSRF defaults, so redirects to private/internal targets are blocked.

​
Supported parameters

Gemini search supports the standard query and count parameters. Provider-specific filters like country, language, freshness, and domain_filter are not supported.

​
Model selection

The default model is gemini-2.5-flash (fast and cost-effective). Any Gemini model that supports grounding can be used via plugins.entries.google.config.webSearch.model.
