# Get information about what extension version is supported

> Used by the Credible VS Code extension; not part of the external integration surface. The extension calls this before authenticating to learn the minimum supported version, so it is unauthenticated.

  title: Coding API
  description: >-
    Public API for Credible's Code Assist service. Its externally-facing
    capability is a Malloy documentation search (`POST /search_malloy_docs`)
    that any authenticated caller — including a customer's own MCP server — can
    invoke directly with a Group Access Token. The remaining endpoints back the
    Credible VS Code extension and are not part of the external integration
    surface.
