Cal.com GraphQL API
Cal.com does not expose a native GraphQL endpoint. The platform's public-facing API is a REST API (v2, hosted at `https://api.cal.com/v2`), and its internal application layer uses tRPC for client-server communication. The GraphQL schema in this directory is derived from Cal.com's authoritative Prisma database schema at `packages/prisma/schema.prisma` in the open-source repository, which defines all core data models.
