Drop CopBuyer-confirmed UCP cartLive variant revalidation
Drop prep without crossing the checkout line.
Describe the product, color, size, and price you want. Drop Cop checks Supreme's advertised Shopify UCP catalog, revalidates one exact live variant, and can prepare a one-item merchant cart only after you ask. Supreme remains responsible for buyer review, shipping, payment, CAPTCHA, and the final order.

A configured target matched an available official product. Open the official page only if you want to review it manually.
Ready For Human Review
Demo observations never refresh automatically. Live UCP catalog data is requested only when you choose Assess live catalog. A merchant cart is created only when you separately choose Prepare checkout; neither request polls in the background.
Case study
How Drop Cop became a bounded, testable product.
- Status
- Working portfolio beta
- My role
- Product strategy, UCP catalog/cart integration, matching logic, and safety UX
- Current release
- Buyer-confirmed UCP cart handoff
The problem
Drop-day tools often collapse product discovery and purchasing into one risky automation problem. The useful need is narrower: help a shopper describe a target, understand whether a current catalog item matches, and reach the official product page quickly without taking over the purchase.
Product response
Drop Cop turns saved preferences into deterministic match scores, revalidates one exact available variant, and creates one merchant UCP cart only after an explicit shopper action. The returned continuation link moves the shopper to Supreme for every buyer and payment step.
Architecture at a glance
- Validate bounded target preferences on the client and again at the server boundary.
- Discover the merchant-advertised UCP catalog and allow only approved HTTPS hosts and tools.
- Normalize product, variant, price, option, and explicit availability records, then select by ordered color and size preference.
- Re-read the chosen product and create one non-retried UCP cart before returning the merchant continuation link.
Proof, not claims
- The response exposes source, freshness, timestamps, failures, fallback reason, and circuit status.
- Route tests cover discovery drift, malformed products, unsafe cart URLs, unavailable variants, upstream failures, and duplicate-prevention behavior.
- Production-browser tests cover live-match rendering, one-cart preparation, merchant continuation links, and the absence of deprecated checkout demos.
Honest boundaries
- Only the advertised UCP create_cart tool is used; no storefront control, checkout completion, payment, CAPTCHA, queue, stealth, proxy, or credential automation.
- Unknown availability is never promoted to available, and fallback fixtures are never presented as current inventory.
- Catalog checks and cart preparation are separate shopper actions; the state-changing cart call never retries automatically.
Next release
- Prove catalog and cart reliability during real release windows and expose source-health metrics.
- Add private, user-controlled target persistence and optional time-boxed drop reminders.
- Measure time from live match to merchant handoff without weakening buyer-confirmation boundaries.
