Acceptance of terms
By accessing or using UCP Checker & Validator (the "Service"), you agree to these Terms and Conditions. If you do not agree, please do not use the Service.
What this service is
The Service is a free tool that checks whether a domain publishes a valid Universal Commerce Protocol (UCP) manifest at /.well-known/ucp, and lets you validate a manifest you paste in directly. It also publishes independent guides about agentic commerce and related standards.
No guarantee of accuracy
The Service is built against the publicly documented UCP specification and is kept up to date on a best-effort basis, but the specification and the broader agentic commerce landscape are actively evolving. A "valid" result from this Service is not a guarantee that any particular AI agent, platform, or payment processor will actually recognize or transact with your manifest, and a low score does not necessarily mean your site cannot be discovered by agents through other means. Always verify against the current specification at ucp.dev for anything business-critical.
The guides published on this site are researched and sourced from primary materials where possible, but they describe a fast-moving space and may become outdated after publication. Always check a company's own current documentation before making implementation decisions based on a guide here.
No affiliation
This Service is independent and is not affiliated with, endorsed by, or officially connected to Google, the UCP working group, Shopify, Stripe, PayPal, Adyen, Adobe, Wix, BigCommerce, or any other company or platform referenced in these guides.
Acceptable use
You agree not to:
- Use the Service to scan domains you do not have permission to test, in a way that violates another party's terms of service or applicable law;
- Attempt to overwhelm, abuse, or automate excessive requests against the Service in a way that degrades it for other users;
- Attempt to reverse-engineer, scrape, or republish the Service's underlying validation logic or content wholesale without permission;
- Use the Service for any unlawful purpose.
Intellectual property
The text, design, and guide content on this site are owned by the Service operator unless otherwise credited, and may not be republished or reproduced without permission, aside from normal fair-use quotation with attribution and a link back. Trademarks, logos, and product names referenced (Google, UCP, Shopify, Stripe, and others) belong to their respective owners and are used here only for identification and commentary.
Third-party links and services
This site links to third-party websites, documentation, and services for reference. We do not control and are not responsible for the content, accuracy, or practices of those external sites. Following a link is at your own discretion.
No warranty
The Service is provided "as is" and "as available," without warranties of any kind, express or implied, including but not limited to warranties of merchantability, fitness for a particular purpose, or non-infringement. We do not warrant that the Service will be uninterrupted, error-free, or available at all times.
Limitation of liability
To the fullest extent permitted by law, the Service operator is not liable for any indirect, incidental, special, or consequential damages arising from your use of, or inability to use, the Service, including but not limited to business losses arising from reliance on a check result or guide content.
Changes to the service or these terms
We may modify, suspend, or discontinue any part of the Service at any time. We may also update these Terms from time to time; continued use of the Service after changes are posted constitutes acceptance of the revised Terms.
Governing law
These Terms are governed by the laws applicable to the jurisdiction in which the Service operator resides, without regard to conflict-of-law principles.
