{"id":112244,"title":"Agentcard: Cards for AI agents","tagline":"Let agents buy anything online","body":"[ ](https://www.youtube.com/watch?v=RaeATYNiBbY)\n**TL;DR**\\\nBuying online with agents is hard. You can't share your card with your agent, browser automations are broken and slow, and most checkout pages block agents, mistaking them for bots. Agentcard gives companies a solution for storing users' credit cards and completing checkout pages with a 99% success rate.\n\n**Ask**: building an agent that buys things on behalf of your users? send us a msg: [founders@agentcard.sh](mailto:founders@agentcard.sh)\n\n![uploaded image](/media/?type=post\u0026id=112244\u0026key=user_uploads/347376/2d085793-25d2-412b-9d20-40785159d157)\n\n**Problem**\n\nCompanies building personal AI assistants want to give their users a simple way to buy using agents. Today, they need to 1) create browser automations to navigate online stores, 2) store users' cards, and 3) complete checkout pages. None of this is their main product. And current solutions don't work: agentic protocols for storing cards have an 8% card acceptance rate (i.e., most of your cards don't work) and are US-only; agentic browsers get blocked when trying to complete a checkout page; companies store cards without being PCI compliant; and, finally, any dispute becomes a problem for the merchant.\n\n**Our solution**\n\n* **Card vault**: a PCI-compliant way to store users' cards.\n* **Agent-browser integration**: native integration with the main agent browsers.\n* **Bring your own browser**: simple integration with your own browser.\n* **Checkout completion**: 99% success rate on the most popular merchants (Shopify, Stripe and others).\n\n**How it works**\n\n![uploaded image](/media/?type=post\u0026id=112244\u0026key=user_uploads/347376/9b3b8719-6d1d-44c1-9995-685b7e2d0036)\n\n1. **Store card**: share a safe link with your customer and store their cards with Agentcard.\n\n![uploaded image](/media/?type=post\u0026id=112244\u0026key=user_uploads/347376/5282b31a-6d30-4a8e-a00d-972dfde54697)\n\n2. **Shop**: with the agent browser of your choice, complete the purchase on behalf of your user using a dummy card.\n\n![uploaded image](/media/?type=post\u0026id=112244\u0026key=user_uploads/347376/612a72b0-6f23-4791-a731-2acc837afe5b)\n\n\n3. **Human authorization \u0026amp; checkout handoff**: share the cart URL with Agentcard and let us complete it.\n\n![uploaded image](/media/?type=post\u0026id=112244\u0026key=user_uploads/347376/de5efb81-bc1a-4caa-ba18-fe25af0f257f)\n\n4. **Success**: we notify you when the purchase is done.\n\n**Team**\n\n![uploaded image](/media/?type=post\u0026id=112244\u0026key=user_uploads/347376/d538ba37-4d5d-4693-a2cb-269790b34248)\n\n* **Karen Serfaty**: CEO @ Agentcard.
