add_gift
ChatGPTUse this when the authenticated user wants to add a product from an online store to one of their MyRegistry gift lists. Requires productUrl. Title and price are strongly recommended — when omitted, title falls back to the URL hostname and price defaults to $0.00, which makes the gift hard to recognise; provide them whenever the page exposes them. If registryId is omitted, the currently active gift list is used; call get_active_gift_list if the target is unclear. Do not use this to search for products, compare prices, purchase items, reserve gifts, or modify gifts already on a list.
