Web Fetch Tool

This document describes the web_fetch tool.

web_fetch

• Purpose: Processes content from one or more URLs (up to 20) embedded in a prompt. This tool is ideal for tasks that require summarizing, comparing, or extracting specific information from web pages.
• Arguments:
  • prompt (string, required): A comprehensive prompt that includes the URL(s) (up to 20) to fetch and specific instructions on how to process their content. For example: "Summarize https://example.com/article and extract key points from https://another.com/data". The prompt must contain at least one URL starting with http:// or https://.
• Behavior:
  • The tool sends the prompt and the specified URLs to the Gemini API.
  • The API fetches the content of the URLs, processes it according to the instructions in the prompt, and returns a consolidated response.
  • The tool formats the response, including source attribution with citations, and returns it to the user.
• Examples:
  • Summarizing a single article:

    web_fetch(prompt="Can you summarize the main points of https://example.com/news/latest")
    

  • Comparing two articles:

    web_fetch(prompt="What are the differences in the conclusions of these two papers: https://arxiv.org/abs/2401.0001 and https://arxiv.org/abs/2401.0002?")
    

• Important Notes:
  • This tool relies on the Gemini API's ability to access and process the given URLs.
  • The quality of the output depends on the clarity of the instructions in the prompt.
