Use this endpoint when you need a quick, affordable per-call email verification paid via USDC on Base, especially within agent workflows on archtools.dev where other tools like email-find or extract-entities are also in use. Ideal for validating individual email addresses before outreach, sign-up flows, or CRM enrichment without committing to a monthly SaaS subscription.

## Known failure modes

- Missing or empty email field returns a 400-level error
- Malformed email string may return invalid format error
- Network or DNS lookup failures for the email domain may return inconclusive result
- Payment failure (insufficient USDC) prevents the call from completing
