UCP Certified

Anyone can say they support UCP. Certified means we ran your endpoint through the full test suite and it passed. End-to-end. No shortcuts.

What the badge means

We run your UCP endpoint through the official conformance suite. Every capability you claim gets tested: product discovery, checkout flow, identity linking, order management, and payment token exchange. If it passes, you are certified. We re-test monthly.

Certification is separate from verification. Verification confirms you own the domain. Certification confirms your implementation is correct.
