Public API

No-auth endpoints for Discover volatility signals, Google Profile checks, and Google News domain checks.

Public API endpoints are no-auth JSON methods for lightweight checks and open signals. Use them to read Google Discover volatility, verify whether a domain has a Google Profile, search Google Profile candidates by entity query, or check whether Google News returns recent RSS items for a publisher domain.
