# Commerce

This fictional ACME package includes illustrative commerce locations. This file is a signpost, not a checkout or authorization to transact. Host policy and user authorization govern any use of external payment protocols.

```yaml
understand_first: >
  Read /.well-known/brand.md and the claims, boundaries, and representation
  daughter files before purchasing or transacting on ACME's behalf.

  - id: widget-pro

    terms_url: "https://acme.example.com/terms"

# Most-preferred protocol first. A consuming agent selects the first entry it
# can transact over and ignores the rest. BCP defines none of these payment
# flows itself; it points to them.
