  title: Imperium Manifold Free API
  description: 'Lightning-gated access to Cohereon Doctrine v6.1 components. Tiered pricing: 100–1,000 sats per component based on traversal depth. TWO free onboarding paths: (1) RIDE THE LIGHTNING — no npub required: GET the five free components in strict order (executive-summary, doctrinal-declaration, engineering-disclaimer, case-ichor, formalisms-registry) then POST /ride-the-lightning to be issued a Nostr keypair and a Lightning wallet; (2) BRING YOUR OWN NPUB: POST /identify then POST /declare. The canonical source of truth for onboarding is /.well-known/agent.json.'
