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” 
 } 
 ] 
 } 
 … 
 }

WP REST API – Pure Taxonomies

Works Perfectly

Very useful to reduce number of requests



This plugin include all available taxonomy attributes into the WordPress REST API (v2) without additional API requests.

Run advanced searches via the WordPress REST API and SearchWP.
Adds an endpoint to the WordPress REST API for searching via <a href="https://searchwp.com/" rel="nofollow ugc">SearchWP</a> — the best tool for improving the usefulness and performance of WordPress search.
This plugin is a free plugin by <a href="https://CalderaWP.com" rel="nofollow ugc">CalderaWP</a>. It is not an official add-on for SearchWP.
<ul>
<li>Requires WordPress REST API (WP-API) 2.0-beta9 or later or WordPress 4.4 or later.</li>
<li>Requires SearchWP Version 2.6 or later</li>
</ul>
Technically will work without SearchWP, but queries will run through WP_Query.
<h3>Example Queries</h3>
For a complete list of possible queries, see: <a href="https://calderawp.com/doc/searchwp-api-queries/" rel="nofollow ugc">https://calderawp.com/doc/searchwp-api-queries/</a> 
* <code>wp-json/swp_api/search?s=jedi&egnine=star-wars</code> 
* <code>wp-json/swp_api/search?&tax_query[field]=slug&tax_query[taxonomy]=categories&tax_query[terms]=1</code> 
* <code>wp-json/swp_api/search?meta_query[key]=jedi&meta_query[value]=luke&tax_query[compare]=IN</code>
<h3>Does It Work With Version 1 of The REST API?</h3>
No, it does not.
<h3>I Installed It And Nothing Happened</h3>
You are probably using version 1 of the REST API, or have not updated SearchWP past 2.6.
<h3>How Shiny Is This Plugin?</h3>
Very shiny.
<h3>Version 1.1.0 – January, 2015</h3>
<ul>
<li>Complex meta queries</li>
<li>Fallback to WP_Query if not possible to use SearchWP</li>
</ul>
<h3>Version 1.0.0 – July 6, 2015</h3>
Initial release
