REST API Inspector

REST API Inspector is a developer tool that displays all registered REST API routes, endpoints, parameters, and properties in a set of organized list tables. It is designed for developers who need to quickly inspect, debug, or understand the API structure of a site without manually searching through code or making live requests.

Key features:

• Route and endpoint list tables – View every registered route and its associated HTTP methods (GET, POST, PUT, DELETE, etc.) in a sortable, filterable table. Each row shows the route pattern, available methods, and callback details.

• Parameter and property inspection – For each endpoint, see the accepted parameters (query, body, path) and their types, required status, and default values. Properties of response schemas are also listed for deeper understanding.

• Schema and handbook links – Row actions provide quick access to the raw schema for any route and a link to the REST API handbook for reference.

• Built on standard list table patterns – The interface follows the same conventions as other admin list tables (posts, users, etc.), making it familiar to anyone who works in the admin area. Each data type (routes, endpoints, parameters, properties) has its own screen with dedicated help tabs.

• Open source and extensible – The code is structured to allow subclassing and customization. It is available on GitHub for contributions, bug reports, and feature requests.
