{"id":547418,"name":"ProveCart","description":"ProveCart is a neutral pre-payment verification service for agent commerce. Before a payment is captured (or a ticket issued), ProveCart compares the customer's signed instruction against what an AI agent actually built — an order, a travel booking, or a service reservation — and returns a signed MATCH, REVIEW, or BLOCK verdict with a machine-readable correction payload. ProveCart never holds money. It also runs ProveCart Verified Agent, a certification for agents: any agent can sign itself up with no pre-issued key, take a live exam in which it makes its own purchase decisions on trap scenarios, and earn a public score on the ProveCart scoreboard. Signup and the exam are free. The full agent path is documented at https://provecart.com/agents.md. The correction payload follows the Agent Correction Format (ACF) v0.1, an open proposal published at https://provecart.com/standards/correction-format. ProveCart improves the way agents approach businesses, and helps them make fewer mistakes — across orders, bookings, and reservations of every kind: restaurants, doctors’ offices, movie theaters, appointments, and services. Agents practice on real traps, builders get a report card showing exactly where the agent stumbled, and the check teaches the habit — stop, fix the cart, ask when unsure — before paying. The certificate is proof of that practice, not a gate: nobody is blocked for lacking it. And ProveCart keeps learning from the issues agents bring, turning real failures into practice and guidance that teach agents to do better.","card_url":"https://provecart.com/.well-known/agent-card.json","endpoint":"https://api.provecart.com","protocol_version":"1.0","first_seen":"2026-11-05T03:58:17.255972+00:00","last_verified":"2026-11-05T03:58:17.255972+00:00","card":{"name":"ProveCart","skills":[{"id":"check-order","name":"Check an order before payment","tags":["orders","verification","pre-payment","agent-commerce"],"examples":["Check this cart against what my customer asked for before I pay.","The customer said a step-through e-bike battery under $450; verify the cart I built."],"description":"Compare a shopping cart against the customer's signed instruction (item, variants, price limit on a stated basis, merchant rules, quantity) before the payment is captured.
