From WordPress content to a REST response.
Three steps in the visual builder. Your content stays in WordPress.
Start with the content already in WordPress.
Choose a post type or taxonomy as your GET endpoint’s source. This real capture shows Posts selected in Endpoint Settings.
Select the fields your application needs.
Add fields to the Active Output Zone and leave unused values out. Here, ID, Title, Excerpt and Featured Image URL are selected.
Check the response before you connect your app.
Inspect a sample of live JSON in the builder, then save and test the endpoint URL. Preview is a sample, not the full paginated response.
A clear path from prototype to production.
Install RKX API Studio Free first. Add the separate Pro plugin alongside it when your project needs ACF mapping, structured block output, or regex formatting.
Deploy with the WordPress workflow you already know.
Install Free from the authorized download, then add Pro from your RKXBeta dashboard. Keep Free and Pro active, then open RKX API Studio → License and activate your license to authorize Pro features.
Choose by what your project needs.
Free is usable on its own. Pro extends the same builder. All commercial Pro plans share the capabilities below.

Installation, licensing and support.
Does Free need an account or license?
No. Free works independently and includes GET endpoints, mapping, queries, caching, import/export and single-key protection.
How do I install Pro?
Install Free first. Download eligible Pro releases from My Plugins, upload the ZIP in WordPress and keep both plugins active. Then activate your license under RKX API Studio → License. Read the installation guide.
Can Pro create and update posts without code?
Write routes dispatch authenticated developer hooks. Your integration must supply validation and the actual operation; they do not automatically perform post CRUD.
What happens if my license expires or validation is offline?
Free remains independent. Qualifying existing activations have a bounded expiration grace window; temporary offline authorization also has a deadline. Private updates require current authorization. Read the license policy guide.
Where can I get help?
Browse the documentation, open a customer support ticket or use Contact for presales and account questions. Send version numbers and reproduction steps with secrets removed.
