  title: Carta API (authentication only)
  version: "0"
  description: "Authentication only. This document describes how to authenticate with the Carta API: its host and its OAuth 2.0 authorization-code and client-credentials flows, and scope names. It lists no endpoints. Carta publishes no OpenAPI specification; every value here comes from the vendor's own documentation, cited per value in x-sources. Checked 2026-11-02: the token endpoint refuses a request with made-up client credentials (HTTP 401)."
