## Description

Advanced REST API DevTools brings the power of Postman directly into your WordPress
admin dashboard. Explore routes, build and test API requests, profile performance,
log traffic, manage collections and environments — all without leaving the admin
area.

**Features:**

 * **Route Explorer** — Browse all registered REST API routes with search, filter,
   and source detection
 * **Request Builder** — Full-featured request builder with method, headers, body,
   auth options
 * **Pre-request Scripts** — Dynamic variable/header manipulation before sending
 * **Test Assertions** — Post-response assertions (status, JSON path, contains, 
   equals)
 * **Collections** — Save, organize, and run request collections with pass/fail 
   results
 * **Environments** — Manage variable sets with {{var}} syntax replacement
 * **Request History** — Browse and reload recent requests
 * **Performance Profiler** — Timing breakdown (routing, permissions, callback, 
   DB queries)
 * **Authentication Debugger** — View current user auth context, caps, and method
   validation
 * **Request Logger** — Opt-in REST API traffic logging with filters and auto-purge
 * **Mock Responses** — Stub mock responses for offline/testing workflows
 * **Code Generation** — Export requests as cURL, PHP (wp_remote_*), or JavaScript(
   fetch)
