Protect Every Email Entry Point

Prevent disposable and repeatedly aliased email addresses from claiming free trials, AI credits, or promo rewards.

🎯 3-State Policy Directives

Direct machine-readable recommendation (allow | review | block). Apply proportionate friction like OTP verification or credit withholding instead of naive blanket rejections.

⚡ Sub-30ms Edge Decisions

Instant in-memory classification across 75,000+ disposable domains, 250+ rotating MX server clusters, and real-time DNS resolution without external network overhead.

🔒 Deterministic Canonical Normalization

Automatically strips provider-specific dots and plus aliases (Gmail, Yahoo, Proton, Outlook) to catch repeated signups on identical mailboxes.

🤖 Built for AI Coding Agents

Native Model Context Protocol (MCP) server support, standardized OpenAPI schema, and copy-paste server recipes designed for Claude Code, Cursor, and Codex.

Next.js SvelteKit Supabase Node.js

🛡️ Privacy-Preserving by Design

Strict multi-tenant isolation with zero plaintext PII storage. All persistent logs record only cryptographic hashes and domain metadata.

🔑 Keyed & Predictable Quotas

Authenticated production API with real-time balance tracking, atomic pre-settlement, and automatic idempotent deduplication.
