The full published terms for a single online storefront: every fee band over basket size, the minimum order, the service area, and where each figure came from. Use to explain a deliveryFee an optimize_delivery plan reported, or to answer 'what do I need to spend for free delivery?'. Take the slug from a plan's serviceSlug. catalogSize and catalogVisibility are reported here only when already known: this tool answers from published terms and never waits on the item count. A null in either means one of two things, and they are not interchangeable: we hold no priced store for this storefront, OR the count has not been taken yet. Call list_delivery_options for a count you can rely on being present; never read a null here as an empty shop.
