UCP Audit — Merchant Readiness Scanner

Scan a merchant's website and produce a UCP readiness report with a 0-100 score, asset inventory, gap analysis, and recommended integration path.

Prerequisites

• Python 3.10+ with requests, beautifulsoup4
• Merchant URL must be publicly accessible

Step 1: Check UCP Profile

1.1. Fetch {merchant_url}/.well-known/ucp

• If exists: parse JSON, validate against profile schema, record capabilities found
• If 404: record as "no UCP profile" (this is expected for most merchants)
• If malformed JSON: record as "broken UCP profile"

1.2. Record:

• has_ucp_profile: boolean
• ucp_capabilities: list of capability names (if profile exists)
• ucp_version: version string (if profile exists)
• profile_errors: list of validation errors (if any)

Step 2: Detect Platform

2.1. Check response headers and HTML for platform signatures:

Platform	Detection Method
Shopify	x-shopify-stage header, /cdn.shopify.com/ in HTML, Shopify.theme in JS
WooCommerce	wc-ajax in HTML, woocommerce in body class, /wp-content/plugins/woocommerce/
Magento	mage/ in scripts, Magento_ in HTML comments
BigCommerce	bigcommerce.com in scripts, data-content-region attributes
Custom	None of the above detected

2.2. Record: platform, platform_confidence (high/medium/low)

Step 3: Inventory Existing Structured Data

3.1. Parse homepage + 2-3 product pages for:

• JSON-LD (<script type="application/ld+json">) — look for @type: Product, Offer, Organization
• Open Graph (og:* meta tags) — title, description, image, price
• Schema.org microdata (itemscope, itemprop attributes)
• Meta tags — product:price:amount, product:price:currency

3.2. For each product page, extract what's already available:

• Product title → maps to UCP title
• Price → maps to UCP price.amount (note currency and whether minor units)
• Description → maps to UCP description.plain
• Images → maps to UCP media[]
• SKU → maps to UCP variants[].sku
• Availability → maps to UCP variants[].availability
• Categories → maps to UCP categories[]

3.3. Record:

• structured_data_types: list of found types (json-ld, opengraph, microdata)
• product_fields_available: dict of {ucp_field: source_field}
• product_fields_missing: list of UCP required fields with no source
• sample_products: 2-3 parsed product examples

Step 4: Detect Payment Methods

4.1. Scan for payment provider signatures:

Provider	Detection
Stripe	js.stripe.com, stripe.com/v3 in scripts
PayPal	paypal.com/sdk in scripts
Adyen	adyen.com in scripts, adyen in form actions
Square	squareup.com, square.com in scripts
Braintree	braintreegateway.com in scripts
Klarna	klarna.com in scripts

4.2. Record:

• payment_providers: list of detected providers
• ucp_payment_handler_ready: boolean (true if Stripe/Adyen/Square detected — these have known UCP payment handler specs)

Step 5: Check API Accessibility

5.1. If platform detected, probe for existing API:

• Shopify: {url}/products.json (public storefront API)
• WooCommerce: {url}/wp-json/wc/v3/ (needs auth but check if endpoint exists)

5.2. Record:

• has_public_api: boolean
• api_type: string (storefront, rest, graphql, none)

Step 6: Calculate Score & Generate Report

Scoring rubric (100 points total):

Check	Points	Condition
UCP profile exists	20	/.well-known/ucp returns valid JSON
UCP profile has checkout capability	10	dev.ucp.shopping.checkout in capabilities
UCP profile has catalog capability	10	dev.ucp.shopping.catalog in capabilities
Structured product data exists	15	JSON-LD or microdata with Product type
All required product fields available	10	title + price + description + at least 1 image
Payment provider detected	15	At least one known provider
UCP-compatible payment provider	5	Stripe, Adyen, or Square specifically
Public product API available	10	Storefront API or REST API accessible
HTTPS enabled	5	Site loads over HTTPS

Report Output Format

Save to store/clients/{client_name}/audit-report.md:

# UCP Readiness Audit — {merchant_name}

**URL:** {url}
**Date:** {date}
**Score:** {score}/100

## Summary
{1-2 sentence assessment}

## Platform
- **Detected:** {platform} ({confidence})
- **Payment:** {providers}

## What You Already Have (Reusable Assets)
{table of existing data that maps to UCP fields}

## What's Missing
{numbered list of gaps, ordered by impact}

## Recommended Integration Path
{step-by-step plan based on platform + gaps}

## Estimated Effort
- Profile setup: {estimate}
- Catalog mapping: {estimate}
- Checkout API: {estimate}
- Total: {estimate}

HARD RULE — Never fabricate data. If a check fails or returns ambiguous results, report it as "inconclusive" with the raw observation. Do not guess platform type or payment provider.
