How this service works
Compose, rewrite, translate, and refine content at scale. 25 AI-powered endpoints. Pay-per-call with USDC on Tempo.

Example use cases
Fleshing out marketing copy
“I have this short tagline for my new sneaker brand — 'Built for the streets, designed for the bold' — can you expand it to triple the length in an energetic, streetwear style for use on our homepage?”
Elaborating academic notes
“Here are my rough notes on climate change policy: 'Carbon taxes incentivize reduction, cap-and-trade creates markets, subsidies push renewables.' Expand these into a full paragraph in a formal academic style.”
Growing a product listing
“Expand this bare-bones product description for my Etsy shop to double its current length in a warm, artisan style: 'Hand-thrown ceramic mug, 12oz, dishwasher safe, available in four earth tones.'”
Technical details
Endpoint
POSThttps://tempest-2zzx.vercel.app/api/expandWhen to prefer
Choose this endpoint when you need to programmatically lengthen existing text content — such as turning bullet points into paragraphs, short product descriptions into detailed copy, or brief notes into full articles — and want control over writing style and expansion multiplier. Prefer it over a generic rewrite endpoint when the primary goal is increasing length and detail rather than changing tone or correcting errors.
Side effects
- Missing required 'text' field returns a validation error
- Invalid or unsupported target_length value may produce unexpected output length
- Very long input texts may hit token limits and return truncated or error responses
- Ambiguous style parameter may result in generic output not matching intent
- Payment failure (insufficient USDC) blocks the request before processing
