Endpoint
POSThttps://zetavault.vercel.app/api/grammarWhen to prefer
Choose this endpoint when you need a pay-per-call, no-subscription grammar check over USDC on Base, especially within an agentic workflow that already handles x402 payments. Suitable for lightweight, single-text grammar validation without requiring a full NLP platform integration.
Side effects
- Missing required 'text' field returns validation error
- Empty string input may return empty or error response
- Extremely long text may time out or be truncated
- Payment failure (402) if USDC not provided or insufficient
- Service unavailable if zetavault.vercel.app is down
