Why teams look for a Google Custom Search JSON API alternative

The daily quota is the wall almost everyone hits. The free allowance is small and the paid tier is capped in a way that makes it unsuitable for anything with real traffic, so the product works beautifully in a prototype and cannot be scaled into.

The second reason is that it was designed to search a site or a curated set of sites rather than to answer arbitrary questions over the open web. Used as a general web search API it is being pushed well outside its purpose, and the result quality reflects that.

Where Google Custom Search JSON API beats us

It is Google's index, reachable with a straightforward JSON API and no scraping in the middle, and for its actual purpose — search restricted to a site or a defined collection of sites — it is excellent and almost free at small volume. If that is the job, this is the tool, and an independent web index is not a substitute for it.

Every page in this section names this. A comparison that cannot say where the other product wins is an advertisement.

The alternatives

unlob

$0.40/1k

We return passages from an index we operate, not a parsed copy of somebody else's result page. That means no dependency on a search engine remaining scrapeable, and results shaped for an agent — metadata first, trust signals attached, page text only for the passages you select. It also means these are not Google rankings, and if that is what you need, a reseller is the right tool.

SerpAPI

$25/1k

The mature multi-engine SERP API. Returns real Google, Bing and Baidu result pages with all their features — at SERP-scraping prices.

No own index· Free: 100 searches per month

Serper

$1/1k

The cheapest way to get raw Google results into an agent. Fast, minimal, and entirely dependent on Google continuing to be scrapeable.

No own index· Free: 2,500 free queries on signup

DataForSEO

$0.60/1k

Industrial SERP infrastructure built for SEO tooling rather than agents. The cheapest per query in the field, with the lowest-level API to match.

No own index· Free: Free trial credit

Parallel Search

$1/1k

A suite of web search, extraction and research APIs on a proprietary index, from the former Twitter CEO. The closest competitor to unlob by thesis.

Own index· Free: 5,000 requests per month

Brave Search API

$5/1k

A genuinely independent index of 40B+ pages, sold as a conventional search API with an LLM-context option. Long the default independent choice.

Own index· Free: $5 in monthly credits — the perpetual free tier was retired in February 2026

Free developer tier removed February 2026

Exa

$7/1k

Neural, embeddings-first search over a proprietary index, sold alongside content extraction, answers and agentic research products.

Own index· Free: $20 in credits at signup, then $10 in credits per month

Grounding with Google Search

$14/1k

Google's first-party grounding for Gemini. The best index in the world, billed per search query on top of tokens, and only usable from Gemini.

Own index· Free: 5,000 prompts per month (Gemini 3.x)

Perplexity Sonar

$14/1k

Search and synthesis in one call. You get an answer rather than results, which is convenient until you need to control retrieval yourself.

Own index· Free: API credits included with Perplexity Pro

Frequently asked questions

What is the best alternative to Google Custom Search JSON API?

It depends what you are replacing. If you need an independent index at the lowest price, unlob is $0.40 per 1,000 queries against Google Custom Search JSON API's $5. If you need Google's exact ranking, Google Custom Search JSON API may still be the right tool — we say so on our comparison page rather than pretending otherwise.

Does Google Custom Search JSON API own its own web index?

Yes — Google's index, via Programmable Search Engine. That matters because a provider without its own index inherits the deprecation and repricing risk of whoever it depends on.

How much does Google Custom Search JSON API cost?

$5 per 1,000 queries after the free allowance, capped at 10,000 queries per day.
