get_category_children
List direct Amazon subcategories under any category node, or top-level departments when no parent is given, to drill down the category tree and map levels.
Instructions
[Amazon category tree drilldown] List direct children from any node (or omit parent to start at the roots). Use when: user says "show me Amazon's category tree" / "subcategories under X" / "list top-level departments" / "drill to level 3"; building a category map; deciding which level is right after search_categories returned candidates. Don't use: when a keyword jump is faster (use search_categories); when you want products in the category, not its subcategories (use list_category_products). Returns: data.items.data[{ browseNodeId, browseNodeIdPath, browseNodeName, browseNodeNameCn, parentBrowseNodeIdPath, productType, sellable, hasChild }] + data.items.pagination.{ total, page, size, hasNext }; omit parentBrowseNodeIdPath to fetch top-level roots; hasChild=1 means the node has further children. Pagination: use the 'page' param (default 1, size default 10 / max 50); 'pagination.hasNext=true' means the node has more children not yet listed. Pair with: ↑ parentBrowseNodeIdPath either omitted (roots) or from search_categories; ↓ feed each result's browseNodeIdPath back in to drill another level, or into list_category_products / filter_categories. Cost: ~1 point/page, ~3s. Only paginate when a node has unusually many children (>size) and the user explicitly wants all subcategories.
