danawa-price-search

This skill compares Korean shopping-mall prices by reading Danawa's public, login-free search and price-comparison surfaces in a strictly read-only way. It solves the problem of finding the true lowest purchase price for a product, going beyond the sticker price to account for shipping-included real cost, free-shipping status, card-discount prices, and installment offers, and doing so conservatively so conditional prices are not mistaken for normal ones.

It ships a Python helper (danawa_search.py) with three commands: search (find product candidates and their pcode by keyword), offers (list per-mall offers for a product), and compare (search then attach offers to candidates). The helper calls Danawa's public search page, product detail page, and a price-comparison AJAX endpoint that returns an HTML fragment, then parses mall names, prices, shipping text, payment-condition badges (cash-only, points, coupon, card, discount, membership), card-discount lines, and installment layers. It outputs JSON only. Offers are sorted by shipping-included total price in ascending order as a single criterion, with conditional prices flagged per row (via fields like payment_condition_label and is_conditional_price) rather than filtered out, so users can judge based on their own payment method. The skill emphasizes read-only behavior and explicitly excludes purchasing, login, cart, wishlist, and ordering actions. Its documented non-goals notably refuse high-frequency crawling and CAPTCHA, access-block, or fingerprint bypass, and its failure modes advise adding throttling/backoff and reporting blocks instead of evading them.

The target users are Korean shoppers and chat-bot builders who want a quick, honest price comparison presented as a Korean-language table. Use cases include finding the cheapest real price for electronics, checking free-shipping and card-discount impact, and surfacing installment options.
