Copyrightish × x402 · x402 demo challenge
This page demonstrates how a publication can advertise an opt-in AI/content license with a copyright.sh-style ai-license signal and protect a machine-readable edition API with an x402 payment challenge.
License signal:
<meta name="ai-license" content="allow; distribution:public; price:0.001; payto:0x01b725582F220432dd4D214DfA9F1452fa8D37Da">x402 resource: /api/license-content/latest
Manifest: /license.json
Settlement mode: x402 demo challenge
Human archive pages remain public. The paid resource is the structured machine-ingestion API, because that is where licensing behavior should be explicit instead of hidden in monkey-click theater.
