  - header
  note: >-
    4Paradigm issues no credentials for anything. Every scheme below is enforced by software you run
    yourself, so "authentication" here means what the shipped default is — and the shipped defaults are
    weak: OpenMLDB runs as root with an empty password unless you turn authentication on, PhanthyMotus
    driver MCP endpoints declare no auth at all, and the one publicly reachable surface is open.
schemes:
- name: ApiKeyAuth
  type: apiKey
  in: header
  parameter: Authorization
  surface: OpenAIOS-Platform, OpenAIOS Billing
  sources:
  - openapi/4paradigm-openaios-billing.yaml
  - openapi/4paradigm-openaios-platform.yaml
  note: >-
    Declared as a raw apiKey in the Authorization header — no scheme prefix (no `Bearer`, no `ApiKey`)
    is specified by the contract, and no key format, rotation or issuance is documented.
- name: OpenID
  type: openIdConnect
  openIdConnectUrl: /.well-known/openid-configuration
  scopes_requested: [openid, email, profile]
  surface: OpenAIOS-Platform
  sources:
  - openapi/4paradigm-openaios-platform.yaml
  note: >-
    The discovery document is relative, so it resolves against the operator's own deployment. No
    4Paradigm-hosted OIDC issuer exists; probed 2026-09-05, every 4paradigm.com host returns a 404 or
    an HTML catch-all for /.well-known/openid-configuration.
- name: OpenMLDB cluster authentication
  type: username-password
  surface: OpenMLDB (SDKs, CLI, APIServer, TaskManager)
  status: alpha, disabled by default
  docs: https://openmldb.ai/docs/en/main/deploy/auth.html
  detail: >-
    Introduced in 0.8.5 and made an explicit alpha in 0.9.0. Off unless every client and server is
    started with --skip_grant_tables=false. Until then the cluster accepts the root user with an EMPTY
    password, and CREATE USER / ALTER USER / DELETE USER are rejected. Credentials are set with SQL
    (`alter user root set options (password='...')`), and the APIServer and TaskManager must
    themselves be reconfigured with --user/--password because they connect as clients.
- name: ZooKeeper credentials
  type: username-password
  surface: OpenMLDB cluster coordination
  status: available since 0.8.4
  docs: https://openmldb.ai/docs/en/main/deploy/auth.html
  detail: >-
    Separate from cluster authentication. Configured as zookeeper.cert=user:passwd (TaskManager),
    --zk_cert=user:passwd (servers and CLI), SdkOption.setZkCert(...) (Java) or zkCert= (Python), and
    it may be passed inside a JDBC URL — which puts a credential in a connection string.
- name: PhanthyMotus driver MCP endpoints
  type: none
  surface: 'http://localhost:<port>/mcp, 16 driver bundles'
  sources:
  - mcp/4paradigm-mcp.yml
  detail: >-
    No auth is declared in any driver.yaml. The security model is the loopback bind plus the private
    network the robot sits on. Identity, pairing and signed requests exist only for robot-to-robot peer
    delegation, not for the tool surface an agent calls.
- name: Sage App Store catalogue API
  type: none
  surface: https://apps.4paradigm.com/api
  method: probed
  detail: >-
    Live, public and unauthenticated — /api/model, /api/model-category, /api/solutions,
    /api/highlights/latest and /api/top-banners all returned 200 application/json to an anonymous
    request on 2026-09-05. Read-only catalogue content; no credential is offered or required.
