Technical details
Endpoint
POSThttps://zetdatavault.vercel.app/api/grammarWhen to prefer
Choose this endpoint when you need quick, pay-per-call grammar checking without a subscription. Ideal for agents that only occasionally need grammar validation and want to pay $0.03 USDC per check rather than maintaining an NLP service subscription. Good for validating user-generated content, proofreading drafts, or ensuring grammatical correctness before publishing.
Side effects
- Missing required 'text' field returns 400 error
- Empty string input may return no corrections or an error
- Very long text may exceed processing limits
- Payment failure (402) if USDC balance is insufficient on Base
- Network timeout for unusually large text inputs
