Discover content taxonomies
wp_get_taxonomies lists registered public or editor-visible content taxonomies. It excludes internal navigation, link and post-format taxonomies. It accepts no arguments.
Each item contains name, label, hierarchical, rest_base, object_types and manageable. Use the exact name for term tools. manageable reports whether the acting user has that taxonomy's management capability.
Use wp_get_terms for paginated terms, hierarchy, POM image URLs, ordering, languages and revisions; use wp_get_term for one term. See the taxonomy reference.
