GET /api/taxonomies

unprobed

Browse the category tree: children of a taxonomy node (roots when parent is omitted), each with subtree product counts and live in-stock counts - walk the tree to find branches with sellable inventory. Payer wallet must be deployed (counterfactual smart accounts are not supported).

Verdict: not verified by an unpaid GET. not probed yet. This says nothing about whether the route works when called as declared.
