How to enable URL Context and Google Search Grounding using this SDK?

[adyingdeath]

The Gemini models support URL Context and Google Search Grounding features, which are very useful. However, after searching online and trying various parameters like extraBody, I still can't figure out how to enable these features through this SDK.

For example, when I provide a Reddit post URL and ask a question about its content, it works in Google AI Studio but fails here—indicating these features aren't properly enabled in my implementation.

I've tried the following approaches without success:

const { text } = await generateText({
  model: openrouter(GEMINI_MODEL, {
    extraBody: {
      tools: [{ urlContext: {} }]
    }
  }),
  prompt: "xxx"
});

const { text } = await generateText({
  model: openrouter(GEMINI_MODEL, {
    extraBody: {
      config: {
        tools: [{ urlContext: {} }]
      }
    }
  }),
  prompt: "xxx"
});

Could you please provide guidance on the correct way to enable these features? Any documentation references or working examples would be greatly appreciated.
