get_products
Get Products
Get full product data (offers, description, attributes, images) by product ID from a search result, or by retailer URL. Pass several IDs in one call to compare.
Use search_products to find products. Returns details in the storefront UI. 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 â including searches for new, unrelated products. Never omit it once you have one.
