Checkout is the hard part, and most solutions clear it only where the merchant has integrated. CartAI completes checkout on any live merchant surface with no merchant-side work, cooperating with bot detection instead of evading it. One developer-first API, four products: Catalog (search and live pricing across merchants), Checkouts (clear and track orders to confirmation), Payments (PCI off your stack via Visa and Mastercard agent rails), Monetization (commissions on every agent sale).
Hey PH 👋 I'm Manil, founder of CartAI. We have been building CartAI for more than a year now and today we're shipping the developer release. The problem we kept running into: every AI agent demo ends right before the part that matters. Browser automation can navigate the web but can't pay. Payment APIs can move money but can't navigate. Your agent gets to the checkout button — and stops.
CartAI is the API that closes that gap. Integrate, point an agent at any web property, and it completes the transaction — checkouts, subscriptions, invoices, orders.
It's four products covering the full transaction lifecycle, with checkout as the wedge everything sits on:
→ Catalog — find the product: search across merchants, live variants + pricing, and checkout estimates before a cart even exists → Checkout — clear the order: complete on the live merchant surface, tracked to confirmation with normalized orders + webhooks → Payments — move the money: hosted, PCI-compliant sessions on Visa Intelligent Commerce and Mastercard Agent Pay → Monetization — share the upside: affiliate commission captured automatically across 70,000+ brands, attribution preserved through to the sale
Three ways to use it: → Automate — your agent runs the full flow autonomously → Embed — drop our agent into your app workflow → Enable — add checkouts to surfaces that never had one. Make any surface commerce enabled.
What's actually hard here isn't the navigation. It's PCI-compliant payment handling, cooperative bot-mitigation so you clear checkout instead of getting blocked (we cooperate with Cloudflare/HUMAN/Akamai/Fingerprint via Web Bot Auth and signed agent identity using Skyfire — we don't evade them), and workflows that always terminate in a known transactional state. That's the part we built.
CartAI clears real orders on production merchants: start to finish, from one API call. There's also an open-source MCP server if you'd rather drop it straight into Claude, Cursor, or your own agent.
Would love your feedback, especially from anyone building agents that need to actually transact. What would you point CartAI at first?

Who hunted CartAI?
CartAI was hunted by Rohan Chaubey. A “hunter” on Product Hunt is the community member who submits a product to the platform — uploading the images, the link, and tagging the makers behind it. Hunters typically write the first comment explaining why a product is worth attention, and their followers are notified the moment they post. Around 79% of featured launches on Product Hunt are self-hunted by their makers, but a well-known hunter still acts as a signal of quality to the rest of the community. See the full all-time top hunters leaderboard to discover who is shaping the Product Hunt ecosystem.
