The Google Custom Search JSON API is shutting down on January 1, 2027, and Google is not offering a drop-in replacement: developers are pointed at Vertex AI Search and Gemini grounding, enterprise products with different pricing and different response schemas. That gives every CSE integration a hard deadline to pick a Google Custom Search API alternative. The migration itself is smaller than it sounds — modern SERP APIs return response shapes close to CSE's items array, so switching is usually one endpoint swap and one field rename. This page compares the four best migration targets for the programmable search engine api replacement decision, starting with Scavio, the closest like-for-like match, with honest coverage of what each one costs, what it adds beyond CSE, and where it falls short.
Why do teams switch from Google Custom Search JSON API to Scavio?
These are common themes from Google Custom Search JSON API users across developer communities, each with a linked source.
1. The Custom Search JSON API shuts down on January 1, 2027
Google is retiring the Custom Search JSON API — the developer API behind Programmable Search Engine — on January 1, 2027. After that date the endpoint stops returning results for free and paid usage alike, and every application, agent, or pipeline still calling it breaks. This is not a version bump: Google is not shipping a successor with the same request-and-response contract. Developers asking where to go are pointed at Vertex AI Search and Gemini grounding with Google Search, which are enterprise-oriented products with different pricing models, different setup, and response schemas that do not map to the items array CSE integrations parse today. In practical terms there is no lift-and-shift Google replacement, which turns the Google Custom Search API shutting down into a migration project with a hard deadline for every team that depends on it.
The counterweight is that the migration itself is small. Several third-party SERP APIs return response shapes close enough to CSE's that switching is usually a matter of swapping one HTTP call and renaming one field, and the ranked list below compares the four strongest migration targets on exactly that basis.
2. The limits CSE users were already escaping
Even before the shutdown was announced, the Custom Search JSON API imposed constraints that pushed production workloads elsewhere. The free tier allows 100 queries per day. Paid usage costs $5 per 1,000 queries and is capped at 10,000 queries per day regardless of how much a team is willing to pay, so any workload above roughly 300,000 queries a month simply cannot run on it. And the API never returned the real Google SERP: results come from the Programmable Search Engine the developer configures, which by default is restricted to a list of sites and, even with whole-web search enabled, applies its own ranking, so top results often differ from what the same query returns on google.com. Structured SERP features — Knowledge Graph panels, People Also Ask, AI Overviews, related searches — were never part of the response at any price.
For teams that tolerated these limits because the API was official and cheap, the retirement removes the last reason to stay. A programmable search engine api replacement has to be chosen anyway, and the third-party options return more data with fewer caps at a comparable or lower price.
3. Waiting until late 2026 to migrate is its own risk
A hard shutdown date changes the economics of procrastination. On January 1, 2027 the API does not degrade gracefully — requests to a retired endpoint fail outright, which means agents and applications that have not migrated stop working at the cutoff, not slowly. Teams that defer the CSE API migration to the final weeks face a compressed schedule: evaluating a replacement under its free tier, mapping response fields, updating parsers, and re-testing edge cases all take calendar time, and a problem discovered in late December leaves no fallback because the old API dies days later. A last-minute rush also runs into ordinary rate and free-tier limits on whichever replacement is being evaluated, exactly when there is no slack left to wait for quota.
Migrating early has a structural advantage: both APIs can run side by side for weeks, letting a team diff responses on real production queries and cut over only when the outputs match, with an instant rollback path if something looks wrong. Because most CSE integrations are a single HTTP call and a response parser, the actual work is small — the risk is almost entirely in the timing, and it compounds the longer the migration waits.

#1
Scavio
Full Google SERP with knowledge graph, PAA, YouTube, and Amazon data
For teams migrating off the Google Custom Search JSON API before the January 1, 2027 shutdown, Scavio is the closest like-for-like replacement, because the response shapes align on the fields that matter. CSE is a GET request that returns an items[] array where each result carries title, link, and snippet. Scavio's Google endpoint is a POST to /api/v2/google with a JSON body of {"query": "..."}, and it returns an organic_results[] array whose entries use the same three core field names: title, link, snippet. In most codebases the CSE API migration is therefore two changes: swap the GET call for the POST call, and rename items to organic_results. Downstream parsing, ranking, and deduplication logic keeps running unchanged, and pagination carries over through the start parameter.
What changes after the swap is how much data comes back. The Custom Search JSON API never returned Knowledge Graph panels, People Also Ask, AI Overviews, or related searches; Scavio includes them as structured fields in the same response, alongside dedicated news, maps, and shopping verticals that CSE had no equivalent for. Integrations that previously stitched together multiple Google APIs to approximate the real SERP collapse into one call, and the MCP server lets Claude and other LLM agents call the same endpoints without wrapper code.
The mechanics are covered by official SDKs — Python via pip install scavio and JavaScript via npm i scavio — with request and response formats documented at scavio.dev/docs/search-api. On price, the $30/month plan includes 7,000 credits, about $4.30 per 1,000 Google searches versus CSE's $5 per 1,000, with no equivalent of CSE's 10,000-query daily cap. The 50 free signup credits, with no card required, are enough to run the field mapping against real production queries and confirm parity before cutting over.
What we liked
- 7 platforms from one API key: Google, YouTube, Amazon, Walmart, Reddit, Instagram, TikTok replace multiple provider subscriptions
- Full SERP anatomy with Knowledge Graph, People Also Ask, AI Overviews, and related searches as typed JSON fields
- No daily query cap; monthly credit pool lets agents burst without hitting mid-day limits
- MCP server with 21 tools and first-party langchain-scavio package for native agent integration
What could be better
- Not an official Google endpoint; scrapes the public SERP rather than using Google's sanctioned API
- Free tier is 50 one-time signup credits with no monthly refill, thinner than Google CSE's 100/day free tier
- Newer product with a smaller community compared to Google's extensive documentation and Stack Overflow coverage
Pricing
| Plan | Price | Credits | Includes |
|---|---|---|---|
| Free | $0 | 50 one-time signup credits | All 7 platforms, No credit card required, 2 req/s rate limit |
| Starter | $30/mo | 7,000 credits | All endpoints, Email support, 2 req/s rate limit |
| Growth | $100/mo | 28,000 credits | All endpoints, Priority support, Higher rate limits |
| Pro | $200/mo | 60,000 credits | All endpoints, Priority support, Custom rate limits |
Our verdict
Scavio is the most direct migration target for the Custom Search JSON API shutdown. The response schema keeps CSE's core field names — title, link, snippet — so most integrations migrate by swapping the endpoint call and renaming items to organic_results, and the payoff is SERP data Google's official API never exposed: Knowledge Graph, People Also Ask, AI Overviews, plus news, maps, and shopping verticals. At about $4.30 per 1,000 Google searches it also undercuts CSE's $5 rate, with no daily cap. The trade-off is that it is not an officially sanctioned Google endpoint, which matters for compliance-sensitive environments.
#2
SerpAPI
Mature SERP scraping across 60+ search engines
SerpAPI is a common migration target for teams leaving the Google Custom Search JSON API ahead of the January 1, 2027 shutdown, particularly when the roadmap involves more than Google. Its Google engine returns the full SERP — organic results, Knowledge Graph, People Also Ask, local pack, and shopping results — as structured JSON, all data the retiring CSE API never exposed. The response schema is well-documented and stable, and the Python and Ruby clients are mature. Where SerpAPI stands out is engine breadth: it supports 60+ search engines including Google, Bing, Baidu, Yandex, DuckDuckGo, and niche engines like Apple App Store and Google Scholar. For teams treating the forced migration as a chance to add multi-engine SERP diversity, nothing else comes close. The downsides are cost and platform depth. At $50/month for 5,000 searches on the Developer plan, SerpAPI is roughly 2x the per-query cost of CSE's $5 per 1,000. It also lacks YouTube transcript endpoints, Amazon product detail lookups by ASIN, and Reddit thread extraction, and its real-time scraping adds latency compared with the old CSE endpoint. For migrations that specifically need Google plus YouTube plus Amazon from one provider, SerpAPI still requires supplementary integrations.
What we liked
- Full Google SERP structure including Knowledge Graph, People Also Ask, local pack, and shopping results
- 60+ search engines: broadest engine coverage of any SERP API including Baidu, Yandex, and DuckDuckGo
- Mature Python, Ruby, and Node.js SDKs with stable schemas and extensive documentation
- 100 free monthly searches with no credit card required for evaluation
What could be better
- Per-search cost of $0.010-$0.050 is 2-10x higher than Google CSE's $0.005
- No YouTube transcript endpoints, Amazon ASIN lookups, or Reddit thread extraction
- Higher response latency from real-time SERP scraping
Pricing
| Plan | Price | Credits | Includes |
|---|---|---|---|
| Free | $0 | 100 searches/month | All engines, No credit card required |
| Developer | $50/mo | 5,000 searches | All engines, Email support, JSON + CSV output |
| Business | $250/mo | 30,000 searches | All engines, Priority support, Dedicated account manager |
| Enterprise | $500+/mo | 100,000+ searches | Custom volume, SLA, Phone support |
Our verdict
SerpAPI is the best Custom Search JSON API migration target for teams that want the shutdown to double as an upgrade to multi-engine coverage. It returns the Knowledge Graph, People Also Ask, and rich snippets that Google's official API withheld, plus Bing, Baidu, and Yandex from one provider. The trade-off is higher per-query cost and missing platform depth for YouTube, Amazon, and Reddit. Google-heavy, cost-sensitive migrations get better per-query economics elsewhere on this list.
#3
Serper
Fast, lean Google SERP API at very low per-query cost
Serper is the migration target to pick when the entire Custom Search workload is Google web search and the priority after the shutdown is the lowest per-query cost. Serper's $50/month plan includes 50,000 queries, an effective rate of $0.001 per search, roughly 5x cheaper than the $0.005 that CSE charged. The API surface is deliberately minimal: send a query and get back organic results, a knowledge graph when available, and People Also Ask. That already exceeds what the Custom Search JSON API returned, since CSE included none of those rich sections, and Serper's synchronous responses are fast. The trade-off is singular focus. Serper only does Google. There are no YouTube transcript endpoints, no Amazon product lookups, no Reddit data, and no content extraction. If an agent needs to pull a YouTube video summary or compare Amazon product specs, a second provider becomes necessary. For pure Google SERP at high volume after CSE retires, Serper is hard to beat on price.
What we liked
- Lowest per-query cost for Google SERP data at $0.001 per search on the $50/month plan
- Returns Knowledge Graph and People Also Ask that Google CSE does not include
- Fast synchronous responses for Google SERP queries
- 2,500 free one-time queries for evaluation, generous for thorough testing
What could be better
- Google only: no YouTube transcripts, no Amazon products, no Reddit, no content extraction
- No official MCP server or first-party LangChain package; community wrappers exist but lag behind
- Limited SERP depth: missing AI Overviews and some Knowledge Graph detail compared to SerpAPI
Pricing
| Plan | Price | Credits | Includes |
|---|---|---|---|
| Free | $0 | 2,500 queries (one-time) | Google Search, No credit card required |
| Standard | $50/mo | 50,000 queries | Google Search, Images, News, Scholar |
| Scale | $150/mo | 250,000 queries | All engines, Priority support, Higher limits |
Our verdict
Serper is the best Custom Search JSON API migration target for teams that only need Google web results and want to minimize cost per query after the shutdown. At $0.001 per search it undercuts CSE's $0.005 rate by 5x and returns richer SERP data, including Knowledge Graph and People Also Ask. The limitation is that it does nothing beyond Google, so agents that eventually need YouTube, Amazon, or Reddit data will outgrow it and need a multi-platform provider.
#4
SearchAPI
Real-time multi-engine SERP API with structured JSON
SearchAPI is a middle-ground migration target for Custom Search JSON API users: broader than CSE was, without SerpAPI's premium pricing. It returns Knowledge Graph data, People Also Ask, and organic results that track live Google SERP rankings more closely than the retiring CSE API did, in a clean, well-typed response schema. SearchAPI supports Google, Bing, Baidu, YouTube Search, Google Scholar, Google News, and Google Maps, which makes it a broader replacement than CSE without reaching SerpAPI's 60+ engine count. The pricing is competitive: $40/month for 5,000 searches on the Standard plan, a per-search effective rate of $0.008. That is 60% more than CSE's $0.005 per query but includes SERP features that CSE charged separately for via other Google APIs, when it offered them at all. The main limitation is platform depth. SearchAPI returns YouTube search results but not transcripts. It has no dedicated Amazon or Reddit endpoints. The free tier of 100 searches per month is enough for a quick migration test but disappears fast during integration work.
What we liked
- Returns full SERP structure including Knowledge Graph, People Also Ask, and featured snippets
- Multi-engine support covering Google, Bing, Baidu, YouTube Search, and Google Scholar
- Clean JSON schema with consistent response structure across all supported engines
- Competitive pricing at $0.008 per search with a 100-search free tier
What could be better
- No YouTube transcript endpoint; returns search metadata only, not video content
- No dedicated Amazon or Reddit endpoints; limited to search engine results
- Smaller ecosystem with fewer community integrations than SerpAPI or Google CSE
Pricing
| Plan | Price | Credits | Includes |
|---|---|---|---|
| Free | $0 | 100 searches/month | Google, Bing, Baidu, No credit card required |
| Standard | $40/mo | 5,000 searches | All engines, Email support, JSON output |
| Professional | $100/mo | 15,000 searches | All engines, Priority support, Webhooks |
| Enterprise | $250+/mo | 50,000+ searches | Custom volume, SLA, Dedicated support |
Our verdict
SearchAPI is a solid Custom Search JSON API migration target that returns the full SERP anatomy at a reasonable price point. It fills the gap between what CSE returned and SerpAPI's premium pricing, with enough engine diversity for most workloads. The limitation is the same as SerpAPI: no YouTube transcripts, Amazon product details, or Reddit data. For migrations that need multi-platform coverage beyond search engines, a provider like Scavio covers more ground from a single key.

Try Scavio FreeWhen should you stay with Google Custom Search JSON API?
Google Custom Search still makes sense in exactly two cases. If the need is a site-restricted search box on your own website rather than an API, the embedded Programmable Search Engine element is a separate product that continues past the shutdown. And for very low-volume hobby projects that fit inside the free tier of 100 queries per day, the JSON API remains usable until it retires on January 1, 2027.
For everything else — production applications, AI agents, any workload that must keep running past the deadline — the question is not whether to migrate but where. Scavio returns organic results with the same core field names CSE uses (title, link, snippet), so most integrations move with an endpoint swap and a single field rename, and gain the Knowledge Graph, People Also Ask, and AI Overview data the official API never exposed.
How do we compare Google Custom Search JSON API alternatives?
We compare each tool on the criteria below using its public documentation, pricing pages, and reported developer experience, weighting the factors that matter most for AI agents and search pipelines.
| Criteria | Weight |
