# Fetch URL

> Use this tool when you need to retrieve content from URLs, solve problems like accessing web documentation or gathering online information, and interface with JSON-RPC style requests from stdin to receive formatted responses. It handles tool calls asynchronously and provides proper error handling, making it ideal for AI assistants that require web content access during conversations. The Fetch URL tool is particularly useful in contexts where online information retrieval is necessary, such as checking resources or gathering data from specific websites.
