Google Search API Deprecation 2027

A SaaS company using Google CSE for their internal documentation search tested migration to Scavio. They changed 3 lines of code: the endpoint URL, the auth header, and the response field mapping. Testing with 500 queries (free tier) confirmed identical result quality. They scheduled production migration for November 2026, two months before the CSE deadline.

Google Search API Deprecation 2027 is relevant to Google. Scavio provides a unified API to access data from all of these platforms.

Google Custom Search Engine (CSE) has been the primary official way for developers to access Google search results via API since 2010. In 2026, Google announced two critical changes: new CSE signups are closed (existing users retain access), and on January 1, 2027, the 'search entire web' feature will be removed. After that date, CSE will only search within sites you explicitly configure -- it becomes a site search tool, not a web search tool. This affects millions of applications: AI agents using CSE for web grounding, SEO tools using CSE for rank tracking, research tools using CSE for data collection, and internal tools using CSE for documentation search. The migration path: switch to a third-party search API before January 2027. Migration is straightforward because CSE and third-party APIs both use REST with JSON responses. Scavio's API returns the same core data (titles, URLs, snippets) plus additional data CSE never provided (AI Overviews, Knowledge Graph, People Also Ask). Pricing comparison: CSE charged $5/1,000 queries (after 100 free/day). Scavio charges $5/1,000 queries ($0.005/credit). Cost parity, but with more data fields and multi-platform coverage. For teams planning migration, the recommended approach: (1) sign up for Scavio free tier (250 credits/month), (2) update your HTTP endpoint URL and auth header, (3) map CSE response fields to Scavio response fields (most map directly), (4) test with your existing query patterns, (5) switch production traffic before December 2026.
