What it checks
UCP aims to give agents one way to browse a catalogue, build a basket, and check out across different merchants.
The extension requests /.well-known/ucp.json and /.well-known/ucp, in that order, and passes on the first one that
returns a non-empty JSON document.
Commerce protocols are new, and most sites have no reason to support them, so absence is N/A rather than a failure.
Results
| Status | When |
|---|---|
| Pass | One of the paths returns a non-empty JSON document |
| N/A | Nothing was found |
How to fix
Publish a UCP descriptor at /.well-known/ucp.json to expose your commerce capabilities to agents. Serve it as JSON (Content-Type: application/json); the extension only
confirms a JSON document is there and does not validate its contents.
These standards are still settling, so follow the protocol’s own documentation for what the descriptor should contain.
