AIOSEO REST API allows developers to interact programmatically with the All in One SEO (AIOSEO) plugin’s features on a WordPress website. It provides a set of endpoints that enable external applications or other plugins to access and manipulate AIOSEO data, such as SEO settings, metadata, and other configuration options, without needing to access the WordPress admin interface directly. The REST API can be used to automate SEO tasks, integrate AIOSEO with third-party tools, and retrieve or update SEO-related information on the website in a structured way, making it easier to manage SEO at scale or integrate it with custom workflows and applications.
