Prism is a payment gateway that enables merchants and e-commerce platforms to accept payments from AI shopping agents. When an AI assistant purchases something on behalf of a user, Prism handles the stablecoin settlement — instant finality, zero chargebacks. A single integration covers multiple commerce protocols including x402, ACP, and UCP, so you’re ready regardless of which protocol your buyers’ agents speak. Think of Prism as Stripe for agentic commerce. Where Stripe settles in fiat via card rails, Prism settles in stablecoins on-chain. Both can coexist — different rails for different types of buyers.

​
Why Agentic Commerce?

E-commerce platforms are already building for AI agents. Major headless platforms are implementing protocols like ACP (OpenAI) and UCP (Google) — enabling AI agents to discover products, add to cart, and check out programmatically. But these protocols handle the commerce flow. They don’t handle settlement. That’s the gap Prism fills. Platforms have built the checkout experience. Prism completes the stack with settlement infrastructure — the layer that actually moves money between agent wallets and merchants.

​
How It Works

  1. An AI agent requests a resource from the merchant’s protected endpoint
  2. Prism middleware responds with HTTP 402 — payment required, specifying amount, token, and chain
  3. The agent’s wallet sends a stablecoin payment on-chain
  4. The agent retries the request with payment proof
  5. Prism verifies the on-chain transaction via the Spectrum settlement layer
  6. The request proceeds — the merchant has the money, settled and final
When the agent uses an Agent Wallet, the entire flow stays within one ecosystem — agent wallet to Prism to merchant settlement. No intermediaries.

Core Capabilities

  • Agent Payment Acceptance — Accept purchases initiated by AI agents shopping on behalf of users
  • Stablecoin Settlement — Instant on-chain settlement in the tokens merchants configure
  • Zero Chargebacks — Stablecoin transactions are final. No disputes, no clawbacks
  • Protocol Agnostic — x402 and UCP live today; ACP support coming soon. One integration covers all
  • Platform-First Architecture — Integrate once, enable all your merchants
  • Multi-Chain Support — Settlement on any EVM-compatible chain

​
Two Integration Paths

​
For Platforms

Integrate Prism as a payment option in your platform. Your merchants can accept agent payments without individual integrations — you handle it once at the platform level.

​
For Merchants

Connect directly via the Prism Gateway API, server-side SDKs, or the Prism MCP Server. Accept agent purchases and receive instant stablecoin settlement to your wallet.
