  Spin is an open source framework by Fermyon for building and running fast, secure,
  and composable cloud microservices with WebAssembly. Spin provides a developer
  experience for creating event-driven serverless applications that compile to WebAssembly
  and run on any platform that supports the Spin runtime including local dev environments,
  Kubernetes (via SpinKube), and Fermyon Cloud.

    name: Spin HTTP Trigger API
    description: >-
      The Spin HTTP Trigger API handles incoming HTTP requests and routes them to
      the appropriate Spin component. Components receive an HTTP request object and
      return an HTTP response. Supported via the Spin SDK in Rust, Go, Python,
      JavaScript, and other languages that target WASI.

    name: Spin Key-Value Store API
    description: >-
      The Spin Key-Value Store API provides Spin components with access to a persistent
      key-value storage service. Components read, write, and delete key-value pairs
      using the Spin SDK. The underlying store can be an in-memory store (for development),
      Redis, or cloud-managed storage depending on the deployment target.

    name: Spin SQLite API
    description: >-
      The Spin SQLite API provides Spin components with access to an embedded
      relational database. Components can execute SQL queries and statements using
      the Spin SDK's SQLite interface, enabling structured data persistence within
      Spin applications.

    name: Spin Serverless AI API
    description: >-
      The Spin Serverless AI API enables Spin components to run AI inference using
      built-in language model support (Llama 2, CodeLlama, etc.) via the Spin SDK's
      infer() function. Components must declare the ai_models they need in spin.toml.
      Supported on Fermyon Cloud and SpinKube deployments.

    name: Spin Variables API
    description: >-
      The Spin Variables API provides runtime access to application configuration
      variables defined in spin.toml. Variables can be required or optional with
      defaults, and can be marked as secrets. At runtime, variables are resolved
      from environment variables, Vault, or other configured providers.
