Technical details
Endpoint
POSThttps://nexus-api-peach-nine.vercel.app/api/ai/grammarWhen to prefer
Use this endpoint when you need a pay-per-call grammar check with no API key setup, particularly in automated agent workflows on the Base blockchain payment rail. Suitable for one-off grammar validation tasks where setting up a subscription-based grammar API is overkill.
Side effects
- Empty query string returns an error or empty result
- Very long input may exceed processing limits
- Non-English text may produce inaccurate results
- Ambiguous or highly technical text may yield false positives
- API returns generic 402 Payment Required if USDC payment not attached
