Agentcard
Let agents buy things online
Agentcard is a B2B payment infrastructure for companies building AI agents, letting agents complete purchases at online checkouts using customers' or company cards. It addresses the problem of storing cards securely, obtaining user approval, and routing purchases to merchants without exposing raw card numbers to the agent or integrator.
The platform comprises three products: Vault, which stores customers' cards encrypted on-device with passkey approval and supports auto-approval thresholds, rewards routing, and white-labeling; Issuing, which creates one-time and multi-use Visa cards funded via USDC on Base with spend limits and merchant restrictions; and the Purchase Agent, an API and MCP tool that completes purchases across supported merchants. Integrations include agent browsers (Kernel, Browserbase, Browser Use, Anchor), messaging platforms (iMessage via Linq, Blooio, WhatsApp), and payment processors such as Stripe, Shopify, and Adyen.
Agentcard is sold to consumer apps, B2B companies, and crypto teams. Vault is available as a free plan up to 5,000 users with an enterprise tier for unlimited users, SSO, and SLA; Issuing is a monthly plan with a revenue share per transaction plus an enterprise edition; the Purchase Agent is usage-based per request and free during beta.
