What problem does it solve? Daangn Market's web search only shows listings from a single selected neighborhood, with no nationwide search option. This Skill solves that by iterating region IDs so you can find rare items like large appliances or laptops that never appear in just one neighborhood. ## Core Features & Use Cases - Wide-Area Crawling: Iterates administrative region IDs (Seoul districts mapped to ID ranges, plus other provinces) to search entire cities or the whole country. - Listing Parsing: Extracts title, price, neighborhood, and time from server-rendered search result HTML using fetch only, no browser required. - Rate-Limit Handling: Applies safe concurrency (2-3 parallel, 250-450ms intervals) with 403 backoff guards to avoid CloudFront blocking. - Use Case: You want a used washer-dryer combo. Run searches for "콤보", "세탁건조기", and "워시타워" across hundreds of Seoul neighborhoods, deduplicate by URL, filter noise, and sort by price to see the market distribution. ## Quick Start Search Daangn Market across all of Seoul for washer-dryer combo listings and summarize the price distribution.
