## Products

### Shield — Device Intelligence for Stripe Radar
Shield is a drop-in Stripe.js replacement that enriches every PaymentIntent with device, network, and session signals so you can write stronger, more accurate Radar rules.

Key features:
- One-line frontend integration, 15KB script
- No backend changes required
- AI-powered Radar rule recommendations
- Device fingerprinting, session intelligence, real-time risk scoring
- Payment enrichment: attaches device, network, and session signals to each PaymentIntent
- Adaptive Radar rules: analyzes fraud patterns and suggests rule updates automatically

Pricing: $0.05 per enriched PaymentIntent, 1,000 free. No minimums, no contracts.

How it works:
1. Install the Shield App via the Stripe App Marketplace
2. Add the Shield script next to Stripe Elements (replace loadStripe() with Shield.Shield())
3. Shield enriches PaymentIntents with metadata usable directly in Radar rules

### Chargeback AI — Automated Dispute Response for Stripe
Claude Code plugin that responds to Stripe disputes in minutes. Pulls dispute details, generates submission-ready rebuttal letters, and audits your evidence — all from the terminal.

Key features:
- Two installs, zero code (Claude Code + Stripe MCP)
- Reason-code-aware rebuttals (Visa, Mastercard)
- Evidence checklist with gap analysis and win-condition identification
- Free — open source Claude Code plugin

How it works:
1. Point it at a dispute: /chargeback-ai:respond ch_your_charge_id
2. Get a submission-ready rebuttal written for your specific dispute, reason code, and evidence
3. Get an evidence audit showing what you have, what's missing, and what wins

Setup:
```
# Connect Stripe to Claude Code
$ claude mcp add stripe
# Install Chargeback AI
> /plugin marketplace add go-canonical/chargeback-ai
> /plugin install chargeback-ai@chargeback-ai
# Fight your first dispute
> /chargeback-ai:respond ch_your_charge_id
```

### Checkout — Hosted Checkout (Launching Soon)
A Canonical-hosted checkout for merchants on Stripe Hosted Checkout who want more from Radar. Full Shield signal capture, stronger Radar rules, better dispute outcomes — without touching your payment flow.

Key features:
- Drop-in replacement for Stripe Hosted Checkout
- Full device + session signal capture built in
- No frontend work required

## Services

We're ex-Stripe Merchant Risk. We use AI to find fraud patterns human review misses, build Radar rules default tooling can't write, and investigate incidents at machine speed.

### Custom Radar Rules
We write Radar rules using signals most merchants can't access — device fingerprints, session behavior, velocity patterns. AI analyzes your transaction history to find the rules that would have caught fraud your current setup missed. Not generic threshold tweaks — rules built from your data, for your fraud patterns, in your vertical.

### Fraud Investigation
When fraud spikes or coordinated attacks hit, we investigate. AI-assisted analysis across your payment data surfaces fraud rings, synthetic identities, and attack vectors — then we build controls to block them. Incident response at machine speed with pattern detection across millions of transactions.

### Sigma & Data Analysis
Stripe Sigma gives you SQL access to your payment data. We write the queries that matter — surfacing fraud patterns, modeling revenue impact, and building the data foundation for smarter rules. AI-assisted query generation that finds what you didn't know to look for.

### Engagement Process
- Phase 1 — Discovery (Week 1): Connect to Stripe, run Sigma queries, map fraud surface. Outputs: fraud surface map, risk segmentation, dispute trend analysis, revenue leakage estimate.
- Phase 2 — Build (Weeks 2–3): Write custom fraud rules tested against historical data. Outputs: custom Radar rule sets, device fingerprinting integration, velocity and behavioral rules, A/B test framework.
- Phase 3 — Deploy & Monitor (Ongoing): Shadow mode first, then enforcement. Outputs: shadow mode validation, gradual rollout, weekly performance reports, continuous rule adaptation.

### Free Fraud Scan Tool
AI-powered scan that analyzes your domain and identifies potential fraud vectors. No signup, no Stripe connection required.

## Shield Installation Guide

Shield is a client-side drop-in replacement for Stripe.js that enriches your PaymentIntents with device-based risk signals for Stripe Radar. No backend changes are required.

### Step 1: Replace loadStripe() with Shield

**Before (Stripe.js):**
```javascript
const stripe = await loadStripe('pk_live_your_publishable_key');
```

**After (Shield):**
```javascript
// Load Shield SDK
const script = document.createElement('script');
script.src = 'https://cdn.gocanonical.com/shield/latest/shield.js';
script.onload = async () => {
  try {
    const Shield = window.Shield;
    if (typeof Shield?.Shield === 'function') {
      // Shield.Shield replaces loadStripe
      const stripe = await Shield.Shield('pk_live_your_publishable_key');
      // Use "stripe" exactly as you would use Stripe.js
    }
  } catch (error) {
    console.error('Error initializing Shield:', error);
  }
};
script.onerror = () => console.error('Failed to load Shield SDK');
document.head.appendChild(script);
```

### Complete Example

```html
<!DOCTYPE html>
<html>
<head>
  <title>Checkout with Shield</title>
</head>
<body>
  <div id="payment-element"></div>

  <form id="payment-form">
    <button type="submit">Pay</button>
  </form>

  <script>
    let stripe;

    const script = document.createElement('script');
    script.src = 'https://cdn.gocanonical.com/shield/latest/shield.js';

    script.onload = async () => {
      const Shield = window.Shield;

      // 1. Replace loadStripe()
      stripe = await Shield.Shield('pk_live_your_publishable_key');

      // 2. Fetch clientSecret from your backend (unchanged)
      const { clientSecret } = await fetch('/create-payment-intent', {
        method: 'POST',
        headers: { 'Content-Type': 'application/json' },
      }).then(r => r.json());

      // 3. Create and mount the Payment Element
      const elements = stripe.elements({ clientSecret });
      const paymentElement = elements.create('payment');
      paymentElement.mount('#payment-element');

      // 4. Handle payment submission (unchanged)
      document.getElementById('payment-form').addEventListener('submit', async (e) => {
        e.preventDefault();
        const { error } = await stripe.confirmPayment({
          elements,
          confirmParams: { return_url: window.location.origin + '/success' },
        });
        if (error) alert(error.message);
      });
    };

    script.onerror = () => console.error('Failed to load Shield SDK');
    document.head.appendChild(script);
  </script>
</body>
</html>
```

**Important:** Replace `pk_live_your_publishable_key` with your actual Stripe publishable key. Make sure the PK you use is from the same Stripe account you install the Shield App from. The Shield SDK initializes asynchronously, so ensure your payment logic runs after the script loads.

### Content Security Policy (CSP) Configuration

If your app uses a strict CSP, add these domains:

1. **Allow Shield SDK script:**
   ```
   script-src ... https://cdn.gocanonical.com;
   ```

2. **Allow Stripe.js:**
   ```
   script-src ... https://js.stripe.com;
   ```

3. **Allow Shield + Stripe network requests:**
   ```
   connect-src ... https://api.gocanonical.com https://cdn.gocanonical.com https://api.stripe.com;
   ```

4. **Allow Stripe Elements and 3DS iframes:**
   ```
   frame-src ... https://js.stripe.com https://hooks.stripe.com;
   ```

**Reference CSP (merge with your existing policy):**
```
Content-Security-Policy:
  default-src 'self';
  script-src 'self' 'unsafe-inline' 'unsafe-eval' data:
    https://cdn.gocanonical.com
    https://js.stripe.com;
  connect-src 'self'
    https://api.gocanonical.com
    https://cdn.gocanonical.com
    https://api.stripe.com;
  frame-src
    https://js.stripe.com
    https://hooks.stripe.com;
  img-src 'self' data:;
  style-src 'self' 'unsafe-inline';
  font-src 'self' data:;
```

### Requirements

- Stripe Elements integration: Shield works with Stripe Elements. Stripe hosted Checkout pages are not supported (use Canonical Checkout instead, launching soon).
- PaymentIntents: Shield enriches PaymentIntents with device-based risk signals. Additional enrichment types (coupons and subscriptions using SetupIntents) are available in Beta.
- Shield Stripe App: We recommend installing the Shield App from the Stripe App Marketplace for the best experience.
