Technical details
Endpoint
POSThttps://tempestars.vercel.app/api/roundupWhen to prefer
Choose this endpoint when you need a fully structured, multi-section newsletter roundup generated in one call, especially when you need tone and audience customization built in. It is ideal for automating recurring email digests or briefings at scale via pay-per-call, without managing your own LLM prompting infrastructure. Prefer alternatives if you need fine-grained control over individual paragraph generation or need to generate non-newsletter content formats.
Side effects
- Missing required 'topic' field returns a validation error
- Vague or overly broad topics may produce generic, low-quality roundups
- Unsupported tone descriptors may be ignored or produce unexpected stylistic output
- Very long or complex section lists may exceed model context limits
- Service may return a non-success flag if the AI generation step fails internally
