    description: >-
      The JetStream wire API provides a protocol-level management interface for
      configuring and operating JetStream streams, consumers, key-value buckets,
      and object stores. Requests are made by publishing to well-known
      $JS.API.* subjects and responses are returned as typed JSON payloads.
      This API underlies all official NATS client SDKs and the nats CLI.

    name: NATS Key-Value Store API
    description: >-
      The NATS Key-Value Store API is a JetStream-backed abstraction that
      provides immediately consistent, persistent associative array semantics.
      Clients can create buckets, get, put, delete, and watch keys, and receive
      real-time change notifications. Buckets are implemented as JetStream
      streams with the KV_ prefix.

    name: NATS Object Store API
    description: >-
      The NATS Object Store API is a JetStream-backed abstraction for storing
      and retrieving arbitrarily large binary objects using a chunking mechanism.
      Objects are identified by a bucket and a name, and the API supports put,
      get, delete, and watch operations for managing stored files and blobs.
