Prism is a payment gateway for AI-agent commerce: it lets your server accept payments from AI agents and settle them on-chain in stablecoins. A single integration implements the protocols a buyer’s agent uses to pay — x402, UCP, and ACP — so you don’t write protocol-specific code or touch a smart contract. When an agent checks out or requests a paid resource, Prism returns the payment requirements (amount, token, chain); the agent’s wallet signs an ERC-3009 authorization; and Prism’s Spectrum layer settles the stablecoin transfer on-chain — instant finality, zero chargebacks. Settlement runs on EVM chains (Base, Arbitrum, BSC, Ethereum) in the tokens you enable (FDUSD, USDC). Integrate through the Gateway API, the server-side SDKs (TypeScript, Python, Java), the MCP server, or a ready-made plugin if you run Saleor, Medusa, Shopware, PrestaShop, or WooCommerce.

​
Why agentic commerce needs a settlement layer

Protocols like x402, UCP, and ACP standardize the commerce flow — how an agent discovers products, builds a cart, and checks out. They stop short of settlement. That’s the gap Prism fills: the layer that moves money from the agent’s wallet to your account, verified and final on-chain. You keep your existing commerce stack; Prism handles the payment.
