This API validates email addresses through format checks, MX record lookup, SMTP probing, and catch-all detection. It is designed for AI agents to efficiently assess and filter out invalid email addresses before further processing, without the need for a user dashboard. The service is accessible via a straightforward JSON response, suitable for automated workflows.
Build an inline email gate for agent-driven outreach, a real-time verifier for lead scrapers, or a pre-send safety check in automation. You get a single JSON response that tells your code whether an address is valid, risky, or invalid and why. The service probes MX and mailbox existence without sending messages and includes catch-all detection and confidence scoring. Note: production API keys are paid (a limited browser demo is free to try).
