### 🌐 Get Website Content Using Dumpling AI

This section starts with a manual trigger, then fetches a list of website URLs from a connected Google Sheet. Each URL is sent to Dumpling AI’s crawl endpoint, which extracts readable content up to a set depth. The response is an array of article-like results. These are then split one by one for individual processing. The `Set` node maps key fields such as the original URL, article title, and cleaned content for each page.
