Better REST API Featured Images is a free WordPress plugin designed to improve the handling of featured images within the WordPress REST API. This plugin provides a top-level field for featured image data, simplifying access without needing to embed media. It enriches the post object response by including detailed image information such as size, URLs, and metadata, which can enhance performance and reduce the number of requests required to retrieve image data.

In addition to streamlining image access, the plugin offers a filter for customization, allowing users to add extra data to the featured image response. This flexibility makes it easier for developers to tailor image handling to their specific needs. The plugin is particularly useful for those who frequently require featured image details without the overhead of additional requests, thereby improving overall efficiency in media management.
