## When to prefer this

Choose this endpoint when you need a fast, per-call email validation without a monthly subscription commitment, paying only $0.01 USDC per check via x402 on Base. Ideal for AI agents processing occasional or unpredictable volumes of email verifications where pay-per-use is more cost-effective than a flat subscription.

## Known failure modes

- Missing or malformed email parameter returns error response
- Invalid domain in email may return undeliverable status
- Temporary DNS lookup failures may affect domain verification
- Payment failure via x402 may block the request
- Rate limiting if request volume exceeds plan limits
