🟢search_products(query, image_url, thread_id)

Search 100M+ products across thousands of retailers for one product type. Call once for each distinct product type, and send independent calls together. Put relevant constraints in `query`. Returns up to 8 product cards plus structured product data. The result includes a `thread_id`. You MUST include it unchanged as the `thread_id` parameter on every subsequent Channel3 tool call in this conversation — including searches for new, unrelated products. Never omit it once you have one.
