BillionVerify

BillionVerify is an email-verification service built specifically for AI agents, automation workflows, and high-volume developers. The angle is integration with AI platforms first, verification as a service second.

What it does

• AI-native infrastructure: integrates with Claude, Cursor, and LangChain via MCP or REST API.
• Real-time verification: sub-300ms speeds for instant validation.
• SMTP-level accuracy: multi-layered SMTP checks to detect spam traps, disposable emails, and catch-all domains, with 99.9% claimed accuracy.
• High scale: optimized batch pipelines for millions of emails.
• Enterprise security: 256-bit encryption and GDPR compliance.

Why an AI-first verification service wins

Email verification is increasingly called from automated workflows rather than from a manual UI. A service built around MCP and REST APIs, with AI-platform integration as a first-class concern, fits the actual workflow of a modern AI-driven application better than a traditional verification service with an API bolted on.
