POSThttps://trempest.vercel.app/api/roundupWhen to prefer
Choose this endpoint when you need to programmatically generate structured newsletter roundup content at scale, especially when tone, audience, and section structure must be customizable per call. It is best suited for automated content pipelines, newsletter platforms, or agents that need to produce ready-to-send digest emails without manual editing. Prefer this over generic LLM completions when you want a pay-per-call model with consistent newsletter-specific output formatting.

- Overly vague topic may produce generic or low-quality output
