AI agents are becoming the next commerce channel. Just as merchants once added a mobile app alongside their website, they’ll soon need to serve autonomous agents that shop on behalf of their customers. Prism makes that a drop-in decision: install the plugin for your platform, connect your Prism account, and your store starts accepting agent payments — settled instantly in stablecoins, with zero chargebacks. We maintain official, open-source extensions for five of the world’s leading commerce platforms — together powering hundreds of thousands of live storefronts. If you run one of them, you’re one install away from being agent-payable. If you don’t, the same open protocols let you build the integration yourself.

​
Supported platforms

Each extension is open-source, MIT-licensed, and maintained by Finance District. It adds agent-commerce endpoints to your store — product discovery, checkout, and on-chain settlement — using the Universal Commerce Protocol (UCP) and, where noted, the Agentic Commerce Protocol (ACP). Full install and configuration instructions live in each repository.

Saleor

UCP + ACP for your Next.js storefront. Published as npm packages — no changes to your Saleor backend.

Medusa

UCP + ACP as native Medusa v2 modules. Install, configure, start — no route files, no frontend.

Shopware

A UCP / x402 Prism payment handler for Shopware 6.7. Zero storefront or admin UI.

PrestaShop

UCP + Prism payment modules for PrestaShop 1.7.8, 8.x, and 9.x.

WooCommerce

A WordPress plugin set bringing UCP + Prism settlement to any WooCommerce 8.0+ store.
All five extensions are available today. Each repository includes a quick-start guide and a wiki covering architecture, configuration, and the full request lifecycle.

​
How an integration works

However you install it, every Prism extension follows the same three-step path from install to your first agent payment:
1

Install the extension for your platform

Add the plugin, module, or SDK from the platform’s repository above — npm for Saleor and Medusa, a plugin/module install for Shopware, PrestaShop, and WooCommerce.
2

Connect your Prism account

Generate a Project Identify Token in the Prism Console and drop it into the extension’s configuration. This links agent payments to your merchant account and settlement address.
3

Go live

Your store now advertises a /.well-known/ucp profile. Agents discover your catalog, create a checkout, and pay — Prism settles the stablecoin payment on-chain and hands your store a confirmed, final order. No chargebacks, no intermediaries.
Prism handles all the token, chain, and x402 math behind the scenes — the extension only relays. See How It Works for the full transaction lifecycle.

​
Don’t see your platform?

The extensions above are convenience layers over open protocols — nothing about agent commerce is locked to a specific platform. If you run a custom stack or a platform we don’t yet cover, you can build the integration yourself with the same APIs and be in production quickly.

Custom Integrations

Make any store agent-payable with the Prism APIs, server-side SDKs, and the pluggable payment-handler interface our official extensions are built on.
