Verify the seller's API setup
Probes the supplied endpoints unpaid against the seller’s upstream. Each passes only when the billing guard answers with the payment-required contract. Stateful storefronts ignore the endpoints: verification instead runs structural conformance checks against the seller’s access endpoint (unsigned and mis-signed writes rejected, a signed synthetic write applied twice, a key minted and discarded). The collected set becomes the step’s evidence; all passing marks the step completed, any failure demotes it to in progress.
