NU Signal Partners API
A B2B service for licensing, running, measuring, and settling NU video, webtoon, and interactive IP. Integrate it server-side to browse the catalog, execute license agreements, authorize content through hosted webview links, signed manifests, or Runtime APIs, pass non-PII viewer preferences, send events, and reconcile monthly settlements. This manual is the developer reference.
