## When to prefer this

Choose this endpoint when you need a pay-per-call, no-subscription grammar check via the x402 micropayment protocol on Base. Ideal for agents that need lightweight, on-demand grammar validation without committing to a monthly API key plan, especially in crypto-native or x402-compatible workflows.

## Known failure modes

- Missing required 'input' field returns a validation error
- Malformed input object structure may return a 400 or error JSON
- Empty text input may return ok:true with no corrections
- Service unavailability may return a 402 or 5xx error
- Payment not processed via x402 results in access denial
