Use https:// patterns. An http:// pattern means the merchant's page
loads without TLS — browsers flag it as "Not Secure" and the buyer's session
is visible in plaintext. The Ledewire payment API itself always uses HTTPS,
but the merchant page context matters for user trust.
Setting price_cents to 0 makes all matching URLs freely accessible —
the x402 server short-circuits directly to 200 without a payment round-trip.
Verify the intended price before creating a rule.
