ACTIV Web One API (AtlasFeed) is published by [Options Technology](https://apis.io/providers/options-technology/) on the [APIs.io](https://apis.io/) network. Tagged areas include Market Data, WebSocket, Streaming, Snapshots, and Time Series. The published artifact set on APIs.io includes API documentation, a getting-started guide, and SDKs.

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.
