description: WebSocket-based (WebAssembly) JavaScript/TypeScript market data API for browser and Node.js,
  installed as npm package '@activfinancial/one-api' (latest 1.1.4). Supports snapshots, real-time subscriptions,
  queries, and time-series history across ACTIV's normalized multi-asset feed, with Promises, async/await,
  and AsyncIterator interfaces. Clients connect with activOneApi.connect({ host, user, password }) - tutorials
  document the host aop-ny4-replay.activfinancial.com - and credentials are entitlement-managed and provisioned
  by sales, not self-serve. Documentation, tutorials, examples, and an in-browser playground are public;
  no OpenAPI or AsyncAPI spec is published.
