What's going wrong
Site owners using calendar, checkout, cron, performance and security plugins report that once the REST API is blocked for logged-out visitors, those plugins stop working. Calendars freeze on button clicks, checkout requests fail with unauthorized errors, and scheduled URL actions cannot reach custom endpoints. Owners want a way to allow just the routes a plugin needs without opening everything. Some said the block is simpler to get around with a server rule, but that is risky for non-technical owners. A tool that finds the needed routes and builds a safe allowlist would fix this.
