## When to prefer this

Use this endpoint when you need a pay-per-call, no-subscription email validation service accessible via the x402 micropayment protocol on Base chain. Ideal for agents that need to validate occasional email addresses without committing to a monthly SaaS plan, especially in Web3-native or agentic workflows where on-chain micropayments are preferred.

## Known failure modes

- Missing or malformed email input returns an error
- Email domain has no MX records and is flagged as undeliverable
- Disposable or temporary email service detected
- Network timeout when checking domain DNS records
- Malformed JSON request body returns 400-level error
