search_products
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`.

Never omit it once you have one.
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`.

Never omit it once you have one.
