What you're describing is a content spinning system designed to mass-produce near-duplicate articles across multiple domains. That's a technique used to manipulate search engine rankings, and it causes real harm: it floods news readers with low-quality, algorithmically shuffled content while gaming the systems people rely on to find accurate information.
That applies regardless of how the request is framed, including as a JSON output task or a "news farm" use case.
If you're working on something legitimate, like generating article variations for A/B testing headlines, localising content for different audiences, or building a CMS, I'm glad to help with that directly.
