HOW IT WORKS<br>01Cloudflare catches every email at the edge<br>02Worker parses it, runs Llama 3.1 spam filter<br>03Stored in Redis with 30-min TTL — auto-deleted · Zero cross-test contamination<br>04Dashboard polls every 3s · SDK uses SSE for sub-second delivery in CI<br>05Zero telemetry — we don't track your pipeline, project, or environment

🤖<br>AI Agents<br>Give Cursor, Claude Code and autonomous agents a way to verify real email delivery.

🚀<br>CI/CD<br>Run deterministic auth tests on every deployment. No infrastructure required.

AI can build authentication flows. It still can't reliably verify email delivery without infrastructure. ZeroDrop is the missing layer.
