Google CSE Shutting Down: Migration Guide for 60K+ Req/Month Teams

Google Custom Search Engine (CSE) shuts down January 1, 2027. Teams running 60K+ requests per month need a migration plan now, not in Q4 when everyone panics. The replacement path depends on whether you use CSE for site-restricted search, general web results, or structured data extraction.

What Google CSE Shutdown Means

Google announced the deprecation of Custom Search JSON API in March 2026 with a hard cutoff of January 1, 2027. The free tier (100 queries/day) and paid tier ($5/1K queries) both end. Programmable Search Engine (the iframe widget) continues, but the JSON API that developers actually use does not.

If your product relies on CSE for web search results, image search, or site-restricted queries, you need an alternative API that returns structured JSON. The migration window is about 7 months.

Migration Path for 60K+ Requests/Month

At 60K requests/month on Google CSE, you are paying roughly $300/month ($5/1K queries). The migration target should match or beat that cost while returning equivalent structured data. Scavio handles this at $0.005/credit with the same Google SERP data plus Amazon, YouTube, Reddit, and Walmart.

import requests, os

# Before: Google CSE
# GET https://www.googleapis.com/customsearch/v1?key=KEY&cx=CX&q=query
# Cost: $5/1K queries, shutting down Jan 1 2027

# After: Scavio Search API
H = {"x-api-key": os.environ["SCAVIO_API_KEY"]}

def search_google(query, num=10):
    """Drop-in replacement for Google CSE JSON API."""
    r = requests.post("https://api.scavio.dev/api/v1/search",
        headers=H,
        json={"platform": "google", "query": query},
        timeout=10
    ).json()
    return {
        "items": [
            {
                "title": item.get("title", ""),
                "link": item.get("link", ""),
                "snippet": item.get("snippet", ""),
            }
            for item in r.get("organic", [])[:num]
        ],
        "searchInformation": {
            "totalResults": str(len(r.get("organic", [])))
        }
    }

results = search_google("best crm software 2026")
for item in results["items"]:
    print(f"{item['title']}: {item['link']}")

Handling Site-Restricted Search

If you use CSE for site-restricted queries (searching only your domain or a list of domains), append the site operator to your query string. This works identically to how Google handles the cx parameter internally.

def site_restricted_search(query, site="docs.example.com"):
    """Replaces CSE site-restricted search."""
    r = requests.post("https://api.scavio.dev/api/v1/search",
        headers=H,
        json={"platform": "google", "query": f"site:{site} {query}"},
        timeout=10
    ).json()
    return r.get("organic", [])

Multi-Platform Bonus

The hidden advantage of migrating from CSE: you gain access to platforms CSE never supported. Product teams can query Amazon pricing data, YouTube video metadata, Reddit discussions, and Walmart listings through the same API contract.

# One API, five platforms -- CSE only did Google
platforms = ["google", "amazon", "youtube", "reddit", "walmart"]

def multi_platform_search(query):
    results = {}
    for platform in platforms:
        r = requests.post("https://api.scavio.dev/api/v1/search",
            headers=H,
            json={"platform": platform, "query": query},
            timeout=10
        ).json()
        results[platform] = r
    return results

Migration Timeline for 60K/Month Teams

Week 1-2: Audit every CSE call in your codebase. Document which response fields your code actually reads. Week 3-4: Build an adapter layer that maps Scavio responses to CSE format. Week 5-6: Run parallel queries through both APIs, compare result quality. Week 7-8: Cut over production traffic behind a feature flag. Week 9+: Remove CSE code paths after confirming parity.

At 60K requests/month, Scavio costs about $300/month at $0.005/credit -- roughly the same as CSE. The difference: you get five platforms instead of one, MCP integration for agent workflows, and no deprecation notice hanging over your roadmap.

Cost Comparison

Google CSE: $5/1K queries = $300/month at 60K. Free tier: 100/day. Scavio: $0.005/credit, 250 free/month, $30/month for 7K credits. At 60K/month you would use a custom plan. Both return structured JSON. Scavio adds Amazon, YouTube, Reddit, Walmart, and MCP server access at https://mcp.scavio.dev/mcp.
