Full Explanation
Claude does not have built-in internet access during standard API calls. It relies entirely on its training data and information provided in the prompt. To give Claude access to real-time information, developers must either include relevant content in the prompt or implement tool use with a web search function that fetches data and passes it to Claude. Some Claude-powered products (like Claude.ai) may implement web search as a tool, but this is a product-layer addition, not a base API feature. All three incorrect options falsely claim some form of built-in internet access.
