Technical details
Endpoint
POSThttps://trempest.vercel.app/api/expandWhen to prefer
Use this endpoint when you need to take a short piece of text and automatically expand it to a longer, richer version without manually rewriting it. Ideal for content teams scaling up short copy into full descriptions, marketers elaborating on brief product blurbs, or writers who need a first draft at a longer length. Choose this over a general rewrite endpoint when the primary goal is increasing length rather than changing tone or fixing errors.
Side effects
- Missing required 'text' field returns a validation error
- Invalid target_length value (not 'double' or 'triple') may produce unexpected results or an error
- Very long input text may exceed token limits and return an error
- Payment not included or insufficient USDC balance results in a 402 payment required response
- Network timeout if the AI generation takes too long
