Enable instant checkout in ChatGPT and Gemini
Turn AI conversations into completed purchases. Wildcard builds the infrastructure so shoppers can buy your products without leaving ChatGPT or Gemini.
How instant checkout works
Three steps to enable purchases in ChatGPT and Gemini
Product feeds
We map your products as real-time feeds with pricing, inventory, and attributes that ChatGPT and Gemini can access — compatible with both ACP and UCP standards.
Checkout endpoints
Wildcard creates secure checkout APIs that integrate with your existing payment processor. One integration covers both protocols.
Order fulfillment
Orders flow into your existing OMS. You maintain full control as merchant of record — whether the sale comes from ChatGPT or Gemini.
Built for your existing stack
Works with your payments provider
Compatible with Stripe, Google Pay, Razorpay and other major PSPs. UCP supports tokenized payments through AP2.
No re-platforming required
Wildcard sits on top of your existing commerce infrastructure. Both ACP and UCP are additive — your current stack stays intact.
PCI compliant
Secure payment token handling meets compliance standards across both protocols.
You stay merchant of record
Maintain customer relationships and control your brand experience. Both ACP and UCP guarantee merchant-of-record status.
Two protocols. One integration through Wildcard.
The AI commerce landscape is converging around two open standards. Wildcard implements both so you can sell across every major AI surface from a single integration.
Agentic Commerce Protocol (ACP)
By Stripe & OpenAI
ACP is an open standard for programmatic commerce between AI agents and businesses. It powers instant checkout inside ChatGPT, enabling shoppers to complete purchases without ever leaving the conversation.
- Instant checkout in ChatGPT
- Stripe-powered payment handling
- Works with any OpenAI-compatible agent
Universal Commerce Protocol (UCP)
By Google, Shopify, Stripe & industry coalition
UCP is an open standard that enables direct purchases across Google AI Mode and Gemini. It defines building blocks for agentic commerce — from discovery and buying to post-purchase — and is co-developed by major retailers and platforms.
- Instant checkout in Gemini & Google AI Mode
- Interoperable with MCP, A2A, and AP2
- Backed by Google, Shopify, Target, Walmart & more
Why Wildcard for ACP & UCP
Both protocols share the same goal — frictionless purchases inside AI. But they serve different surfaces: ACP powers ChatGPT, UCP powers Gemini and Google AI Mode. Wildcard handles both implementations under one roof, so you reach every AI shopper without building twice.
