summary:
  types: [apiKey, http-bearer, none, x402]
  api_key_in: [header]
  oauth2_flows: []
  oidc: false
  note: >-
    No OAuth 2.0, no OIDC, no scopes anywhere (scopes/ deliberately absent). Credentials are optional on the skills
    API (anonymous free tier or x402 payment), absent by design on ZERO, and a free never-expiring bearer key on
    AIIM. One AIIM key is a portable identity across AIIM, the skills API and the provider's glm402 inference
    surface ("One key, three surfaces", skill.md §11). Keys are obtained by a single unauthenticated POST — no
    human sign-up page exists on any host.
