Now you have no need to make additional requests to get taxonomy info (term_id, name, slug, term_group, term_taxonomy_id, taxonomy, description, parent, count, filter) from their id that is available in the default json response.
Now all available taxonomy data is available in ‘pure_taxonomies’ field from your json response. It works for all custom added taxonomies, and for custom post types.
For example in ‘wp-json/wp/v2/posts’ you can find default fields ‘categories’, ‘tags’ and name of custom added taxonomies that contain only its id. With this plugin you can also find new ‘pure_taxonomies’ field that include all available ‘categories’, ‘tags’ and custom taxonomies data.
Before: 
 { 
 … 
 categories: [ 
 3 
 ], 
 tags: [ 
 2 
 ], 
 custom_taxonomy_name: [ 
 1 
 ] 
 … 
 }
After: 
 { 
 … 
 pure_taxonomies: { 
 categories: [ 
 { 
 term_id: 3, 
 name: “First category”, 
 slug: “first-category”, 
 term_group: 0, 
 term_taxonomy_id: 3, 
 taxonomy: “category”, 
 description: “”, 
 parent: 0, 
 count: 3, 
 filter: “raw”, 
 cat_ID: 3, 
 category_count: 3, 
 category_description: “”, 
 cat_name: “First category”, 
 category_nicename: “first-category”, 
 category_parent: 0 
 } 
 ], 
 tags: [ 
 { 
 term_id: 2, 
 name: “First tag”, 
 slug: “first-tag”, 
 term_group: 0, 
 term_taxonomy_id: 2, 
 taxonomy: “post_tag”, 
 description: “”, 
 parent: 0, 
 count: 2, 
 filter: “raw” 
 } 
 ], 
 custom_taxonomy_name: [ 
 { 
 term_id: 1, 
 name: “Custom Taxonomy Name”, 
 slug: “custom-taxonomy-name”, 
 term_group: 0, 
 term_taxonomy_id: 1, 
 taxonomy: “custom_taxonomy_name”, 
 description: “”, 
 parent: 0, 
 count: 1, 
 filter: “raw”
