I need a compact WordPress plugin that ships with its own simple form and automatically screens every submitted address against a disposable-email detection API. The plugin must fire the check the moment the user clicks “Submit,” receive a boolean response, and make that result available to me (true = disposable) so I can decide what happens next in my own code or workflow. Key points you’ll build: • A lightweight front-end form packaged inside the plugin. • Server-side call to the API endpoint for each email, returning a clear true/false flag. • If the flag is true, no error needs to appear to the visitor; instead the plugin should expose the result (e.g., via a hook, filter, or metabox entry) so an admin can take further action later. • Clean, well-commented PHP that follows WordPress coding standards and works from WP 6.0 upward. • One-click installation and removal without leaving tables or options behind. Deliverables: the installable .zip, documented hooks/filters, and a short README explaining setup and the exact API request/response format.
