  title: Fauna Core HTTP EventFeeds Schema API
  description: The Fauna Core HTTP API provides direct access to the Fauna serverless document database through HTTPS endpoints. It allows developers to execute Fauna Query Language (FQL) queries, manage databases, perform CRUD operations on documents, manage schema as FSL files, and consume change data capture events via event feeds. The API uses token-based authentication and supports features such as transactions, indexes, and set operations. It serves as the foundation upon which Fauna's client drivers and SDKs are built.
