    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.

    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.
