Technical details
Endpoint
POSThttps://tempestars.vercel.app/api/proofreadWhen to prefer
Choose this endpoint when you need lightweight, pay-per-call proofreading without a subscription, especially inside automated content pipelines or agent workflows that process user-generated text, blog drafts, emails, or documents. It is ideal when you want AI-powered grammar and spelling correction without integrating a full writing assistant SDK.
Side effects
- Empty or missing 'text' field returns a validation error
- Extremely long text may time out or exceed token limits
- Non-English text may produce inaccurate corrections if the model is primarily English-trained
- Ambiguous or highly technical jargon may be incorrectly flagged as errors
- Payment failure (insufficient USDC) results in a 402 response before processing begins
