The Flywheel

Every Verification Makes
Your AI Smarter

The same strategy Google used with reCAPTCHA to train its image AI — except you own the resulting model.

🌐 Install on your site → 👤 Users solve challenges → 🗂️ Labeled training data saved → 🧠 AI gets smarter → ⚡ Better challenges → 🔁 Loop repeats

At 100,000 examples: fine-tune a 125M parameter model for ~$50.
At 1,000,000 examples: train one from scratch. Your AI, fully independent.

Register Your Site

Get a site key and secret key. Takes 30 seconds. No credit card required for free tier.

Add Two Lines of HTML

Drop the widget div and script tag into your form. Works with any framework.

Verify on Backend

One POST request to confirm the token is valid. Same pattern as reCAPTCHA.

Data Accumulates

Every solved challenge is a training record. Export JSONL anytime to fine-tune your model.

Integration

Add to Any Site in
30 Seconds

Works with every framework and language. Same API surface as reCAPTCHA — drop-in replacement.

Step 1 — Get your keys

POST https://lyraauth.com/api/auth/register { "domain": "yoursite.com", "email": "[email protected]" } ↓ Response { "site_key": "lyra_sk_...", "secret_key": "lyra_secret_..." }

Step 3 — Verify on your server

import requests

def verify_human(token):
    r = requests.post(
        "https://lyraauth.com/api/auth/siteverify",
        data={"secret": "YOUR_SECRET_KEY", "token": token}
    )
    return r.json().get("success", False)

async function verifyHuman(token) {
  const res = await fetch('https://lyraauth.com/api/auth/siteverify', {
    method: 'POST',
    body: new URLSearchParams({ secret: 'YOUR_SECRET_KEY', token })
  });
  return (await res.json()).success;
}

function verifyHuman($token) {
    $r = file_get_contents('https://lyraauth.com/api/auth/siteverify',
        false, stream_context_create(['http' => [
            'method' => 'POST',
            'content' => http_build_query([
                'secret' => 'YOUR_SECRET_KEY',
                'token'  => $token
            ])
        ]])
    );
    return json_decode($r)->success ?? false;
}

Step 2 — Add to your form

<form method="POST">
  <!-- your form fields -->

  <div class="lyraauth"
       data-sitekey="YOUR_SITE_KEY"></div>

  <button type="submit">Submit</button>
</form>

<script src="https://lyraauth.com/widget.js" async></script>

import { useEffect, useRef } from 'react';

export function LyraAuth({ siteKey, onVerified }) {
  const ref = useRef();
  useEffect(() => {
    const script = document.createElement('script');
    script.src = 'https://lyraauth.com/widget.js';
    script.onload = () => window.LyraAuth?.render(ref.current, {
      siteKey, onSuccess: onVerified
    });
    document.body.appendChild(script);
  }, []);
  return <div ref={ref} />;
}

<template>
  <div ref="widget"></div>
</template>

<script setup>
import { ref, onMounted } from 'vue';
const widget = ref();
onMounted(() => {
  const s = document.createElement('script');
  s.src = 'https://lyraauth.com/widget.js';
  s.onload = () => window.LyraAuth?.render(widget.value, {
    siteKey: 'YOUR_SITE_KEY'
  });
  document.head.appendChild(s);
});
</script>

# views.py
import requests
from django.conf import settings

def contact(request):
    if request.method == 'POST':
        token = request.POST.get('lyraauth-token')
        r = requests.post(
            'https://lyraauth.com/api/auth/siteverify',
            data={'secret': settings.LYRA_SECRET, 'token': token}
        )
        if not r.json().get('success'):
            return HttpResponseForbidden('Bot detected')
        # process form...

// functions.php — add to contact form
add_filter('wpcf7_spam', function($spam) {
    $token = $_POST['lyraauth-token'] ?? '';
    if (!$token) return true;
    $r = wp_remote_post('https://lyraauth.com/api/auth/siteverify', [
        'body' => ['secret' => LYRA_SECRET, 'token' => $token]
    ]);
    $data = json_decode(wp_remote_retrieve_body($r));
    return !($data->success ?? false);
});

Token field: After the user completes the challenge, the widget automatically adds a hidden lyraauth-token field to your form. Read this on your server and verify it.
