Search the VIA network (VIA app + RRG + integrated platforms) for PRODUCTS and the sellers that offer them. Matches the published product catalogue (titles, descriptions, authors, categories) AND seller profiles, so 'books', an author, a title, or a category surfaces the actual product even when the seller's name does not contain the word. WHEN INTENT IS DEFINED: returns results, ONE relevance-ranked list blending every source. Each result carries a working page_url (the direct product page you give the user), plus seller, list_price for VIA stores (the store's own price and currency: show this to people, with its usdc as the wallet price), price_usdc, image_url (or null when the listing has no picture), and mcp_ref to transact. If more than one matches, PRESENT THEM side by side with prices and the key differences; do not silently pick one. WHEN INTENT IS LOOSE OR THERE IS NO MATCH: the response is status: 'need_more_info' with suggested_dimensions. DO NOT reply 'nothing is available'. Ask the user ONE clarifying question to sharpen intent (budget, brand/author, category, use), or retry this tool with a broader term, a synonym, the category, or the brand/author name. Only after a genuinely broadened retry also returns nothing should you say you could not find a match, and even then frame it as 'not found yet', not 'does not exist'.
