Integrating Emailable with Clay Workflow for Email Verification

Hi friends, I am trying to integrate my email verification app into my clay workflow. I use emailable, however I see no option for it on the clay enrichments. Can I set an API key within Clay to call on Emailable or do I need to set my API call outside the app (ex.apify) and then make an apify call from Clay? What would the process be? And is this possible or is email validation limited to the providers that are within clay enrinchments?
