search_deals
Search deals
Search active (not expired) deals on Pechincha.ai, newest first, 25 per page. Each result has price and old price in BRL, discount %, store, coupon code if any, publication date and the deal page URL. Content is Brazilian Portuguese, so search in Portuguese: `query` matches a literal substring of the title or description, prefer short terms. Accessories that mention the term also match ("notebook" returns backpacks and cables too), so check titles. For a budget ("até R$ 3.000"), pass `max_price`; for a floor or a range ("entre R$ 100 e R$ 200"), pass `min_price` too.
