CustomerOS Website Tracker is one of 4 APIs that [CustomerOS](https://apis.io/providers/customeros/) publishes on the [APIs.io](https://apis.io/) network. Tagged areas include Tracking, Visitor Identification, and JavaScript. The published artifact set on APIs.io includes API documentation.

Client-side JavaScript tracker that captures page views and custom events, exposes window.cos.identify() for attaching identity and properties, and matches visitor IPs to companies. Since the 2025-09-08 change CustomerOS supports it ONLY when served from a reverse proxy on the customer's own domain, so the base URL is templated by design — there is no CustomerOS-hosted CDN URL to record and no version-pinned build.
