Stop Burning Runway on Fake Users.

Relying on basic open-source disposable email checkers creates a false sense of security. While standard regex fails, sophisticated abusers silently drain your infrastructure resources, pollute your conversion metrics, and burn your finite startup runway on AWS bills.

Engineered for B2C / B2B SaaS Scale.

Infrastructure Protection: Stop paying your cloud provider for fake accounts. We programmatically identify and block sophisticated bots at the sign-up gate before they hit your database.
Advanced Evasion Detection: Our API instantly catches sophisticated exploits out-of-the-box, powered by a dynamic rule engine that adapts to your specific threat vectors.
Zero-Friction Integration: Do not waste weeks building custom auth validation flows. Drop our endpoint into your Go, Java, Rust, Node backend and secure your freemium funnel today.

Integration in Seconds, Not Weeks.

curl -X POST "https://api.autheona.com/v1/intelligence" \
  -H "Content-Type: application/json" \
  -H "x-api-key: <access-token>" \
  -d '{
    "email_address": "<email-address>"
  }'

Copy the complete cURL command above and paste it into your AI assistant with this prompt: 'Integrate this API into my sign-up flow and load the access token via environment variables.' You will be fully protected in under 60 seconds.

Built by Founders, for Founders.

We are a security company focused on protecting the PLG funnel. We built this API because we were tired of watching our own server costs explode from free-tier abuse, and we wanted to give technical founders their time back.

Architecture & Evidence.

Dive into our API documentation, review how we handle complex evasion tactics in production, and see exactly why PLG founders choose our infrastructure over bloated enterprise alternatives or failing open-source lists.
