# List organization-facing capability support

> Returns the reviewed support record for every organization-facing capability: its stability, the proof scenarios and revision behind it, the last release it was proven against, and any missing prerequisites when it is not yet available. Use it to check whether a capability can be depended on before building against it. Internal protocol capabilities are not included in this view.

Checkfu support posture: alpha; hosted. Required evidence journey: support-registry. Deployment-specific readiness and the latest proven release are available from GET /v1/support/capabilities.

  version: '2026-08-27'
  description: >-
    Authentication is declared per operation: API-key, runtime, or connector
    bearer; Automation signature; or credential-free pairing redemption. Every
    general Checkfu REST request requires the dated `Checkfu-Version` header
    (one of: 2026-08-27); the three MCP JSON-RPC transports use
    `MCP-Protocol-Version`, A2A uses `A2A-Version`, and the provider OAuth
    callback carries neither Checkfu header. API keys resolve one Workspace
    without a request selector; authenticated responses identify it with
    `Checkfu-Workspace-Id`.
