Example use cases
Tone-matched email drafting
“Take this rough email I wrote to a client and rewrite it in a formal, confident tone while keeping the same core message: 'Hey, just checking in — we haven't heard back about the proposal and wanted to see what's up.'”
Marketing copy style refresh
“Rewrite this product description in a casual, friendly style so it sounds more approachable to a younger audience — but keep all the key product details intact: 'Our device features a high-capacity lithium-ion battery with a 48-hour lifespan and fast-charge capability.'”
Academic paper simplification
“Take this dense academic sentence and rewrite it in plain, simple language without losing the meaning: 'The heterogeneous distribution of socioeconomic resources precipitates differential access to educational attainment outcomes across demographic cohorts.'”
Technical details
Endpoint
POSThttps://tempost.vercel.app/api/rewriteWhen to prefer
Choose this endpoint when you need to transform existing text into a different tone or style rather than generating text from scratch. It is well-suited for content pipelines that need consistent voice adaptation (e.g., formalizing user-generated content, adapting blog posts for different audiences) and when meaning preservation is a priority. Prefer it over a general generation endpoint when the source text already exists and structural changes should be minimal.
Side effects
- Missing required 'text' field returns validation error
- Empty string for text may produce unexpected output or error
- Ambiguous or conflicting tone/style combinations may yield inconsistent results
- Very long texts may hit token limits and be truncated
- Network timeout for unusually complex rewrites
- Insufficient USDC balance results in 402 Payment Required error
