Technical details
Endpoint
POSThttps://tempestars.vercel.app/api/expandWhen to prefer
Choose this endpoint when you need to take a concise piece of text and make it substantially longer while preserving its meaning — ideal for fleshing out drafts, elaborating short descriptions, or padding content to a target length. Prefer this over a general rewrite endpoint when the primary goal is expansion rather than style change or correction.
Side effects
- Missing required 'text' field returns an error response
- Invalid 'target_length' value (not 'double' or 'triple') may produce unexpected output or error
- Very long input text may hit token limits
- Payment failure via x402 protocol returns 402 status before processing
- Network timeout on Vercel serverless cold start
