Technical details
Endpoint
POSThttps://tumpest.vercel.app/api/roundupWhen to prefer
Choose this endpoint when you need a fully composed, audience-specific newsletter roundup with multiple structured sections generated in one call, rather than piecing together individual content blocks from separate endpoints. Ideal for automated newsletter pipelines, content scheduling tools, or agents producing recurring digests.

- Unsupported or ambiguous tone value may produce generic output
