n8n HTTP Tool Tutorial: Build AI Agents with API & Scraping Tools

This n8n workflow is a hands-on tutorial template showing how the built-in HTTP Tool node can dramatically simplify building API-connected AI agents - cutting down what used to take ten separate nodes into one. It includes two working examples: an AI agent that scrapes a webpage and another that fetches data from an external API, both driven by OpenAI's chat model. It's an excellent starting point for developers and n8n builders who want to understand tool-calling patterns and quickly wire single-purpose APIs into their own AI agents without heavy post-processing logic.
