How it works

1. Enter the base URL of the business (e.g. https://shop.example.com).

2. We fetch /.well-known/ucp — the standard discovery endpoint.

3. The returned JSON Business Profile is validated against 18 compliance rules covering profile structure, services, capabilities, namespaces, transports, payment handlers, signing keys, and security.

We will fetch https://…/.well-known/ucp

Authentication (optional)

⚡ Stateless — nothing is stored. The profile is fetched, validated, and discarded.
