UCP checker

Test your site for agent-driven commerce.

Check whether your site supports the Universal Commerce Protocol so AI agents can discover products, link identities, and complete purchases on a buyer's behalf.

  • UCP manifest discovery and validity check
  • Capability declarations: checkout, identity, discovery
  • Transport and authentication conformance
  • Plain-English fixes for every gap we find

What UCP covers

The protocol AI agents actually use.

UCP is the standard interface AI agents follow when they go from researching to buying. If your site doesn't speak it, agents quietly skip you.

AI-driven checkout

See whether your site can let AI agents complete a purchase on a user's behalf with the standard handshake.

Identity linking

Check support for secure account linking between an AI agent session and your existing customer accounts.

Service discovery

Verify your UCP manifest declares the capabilities AI agents look for before they will transact on your site.

Secure transports

Validate that REST, GraphQL, and authentication patterns meet the protocol's transport requirements.

Validation & compliance

Catch schema conformance issues before AI agents do. Stop being silently skipped during agent-driven shopping.

Readiness score

A single score that tells you how close you are to being usable by autonomous agents, and what to add next.

FAQ

Frequently asked questions

Universal Commerce Protocol (UCP) is a standardized interface that enables AI agents to interact with merchant websites for commerce operations, including product discovery, checkout, identity linking, and order management. It allows AI assistants to complete purchases on behalf of users without requiring manual navigation.

As AI agents become more capable of executing tasks autonomously, websites that support UCP will capture commerce from users who delegate shopping to AI assistants. Early UCP adoption positions merchants to benefit from AI-driven commerce before competitors, similar to how early mobile-optimized sites captured mobile traffic.

The readiness score evaluates your UCP manifest presence and validity, supported capability declarations (checkout, identity linking, product discovery), transport protocol compatibility (REST, GraphQL), authentication handling, and schema conformance. Higher scores indicate better AI agent compatibility.

A UCP manifest is a JSON file (typically at /.well-known/ucp.json) that declares your site's UCP capabilities, supported transports, authentication methods, and API endpoints. AI agents discover this file to understand how to interact with your commerce infrastructure programmatically.

UCP is primarily designed for transactional websites, but the protocol is extensible to any site where an AI agent might need to take actions: booking appointments, subscribing to services, or managing accounts. If your site involves any form of user-driven transaction, UCP readiness is worth evaluating.
