Google is retiring its full-web search option for the Programmable Search Engine, forcing partners to transition by January 1, 2027. New engines are now limited to a 50-domain 'Sites to search' feature. Existing setups can continue until the deadline, after which full-web access will require a separate, paid solution.

This shift aligns with Google's broader move to consolidate its search APIs. The company has already deprecated the Custom Search Site Restricted JSON API, pushing users toward Vertex AI Search for advanced features like AI-powered summarization and conversational queries. The change aims to streamline products and improve the developer experience.

Partners querying more than 50 domains must now express interest in Google's full-web solution. Meanwhile, the Programmable Search Element remains the free tool for focused site search. This evolution reflects a larger industry trend where platforms prioritize specialized, AI-enhanced tools over one-size-fits-all APIs.
