  description: |-
    Workflow capability that wraps the Email Verifier API 16-point verification engine. Used by
    growth, marketing, and lead-generation teams to validate email addresses at signup, before
    a marketing send, and during list cleanup. Exposes a single normalized verify-email
    operation as a REST resource and an MCP tool, with credit-balance awareness so AI agents
    can budget verification work against the customer's remaining credits.

            Verify whether an email address is deliverable using the Email Verifier API 16-point engine.
            Returns a top-level status (passed / failed / unknown / transient), a granular event code
            (mailboxExists, mailboxDoesNotExist, isCatchall, isGreylisting, etc.), and intelligence
            flags such as isDisposable, isRoleAccount, isFreeService, and isGibberish. The response
            includes the customer's remaining credit balance so the agent can budget further work.
