# Multivariate Lookups (Deprecated)

> Deprecated: this channel predates RFQs and should not be used for new integrations.

Multivariate collection lookup notifications.

**Requirements:**
- No additional channel-level authentication beyond the authenticated WebSocket connection
- No filtering parameters; subscription is global

**Use case:** Tracking multivariate lookup interest for legacy integrations
