Technical details
Endpoint
POSThttps://tumpest.vercel.app/api/expandWhen to prefer
Use this endpoint when you need to programmatically lengthen a piece of text — such as turning a short draft, summary, or bullet points into a fuller document — especially when you want control over style and expansion ratio. Prefer it over general rewrite endpoints when the primary goal is increasing length and detail rather than changing tone or format.
Side effects
- Missing required 'text' field returns validation error
- Invalid target_length value (not 'double' or 'triple') may cause unexpected behavior
- Payment of 0.2 USDC not sent or rejected causes 402 response
- Very long input text may cause truncation or timeout
- Vague or empty style parameter may result in generic expansion
