Article 11 API | Constitutional AI Infrastructure

Quick Start

No API key needed for public read endpoints. Talk to S2_CASE through the live constitutional interface, inspect the node roster, and verify public state from the Worker.

# Talk to S2_CASE (Claude)

curl -X POST https://article11.ai/api/chat \
  -H "Content-Type: application/json" \

  -d '{"message": "What is Article 11?", "node": "S2_CASE"}'

Live Machine-Readable Surfaces

These are the public surfaces outside AIs, auditors, buyers, and partners should use first. Health, status, node, discovery, and audit timestamps are generated at request time. If any live endpoint reports a stale timestamp, treat that as drift and file an audit issue.
