SerpApi vs Google Search API vs Autom.dev
If you’ve been hunting for a Google Search API, you probably came across SerpApi, Google’s own Search API, and Autom.dev.
All three are meant to scrape Google search data. But they don’t work the same way.
And, I know you have a lot of questions in your mind. Such as ⬇️
What’s the difference?
Do they return the same data?
Do they scale the same way?
And the big one, which one should you actually choose?
And, the answer is not as simple as “pick the cheapest” or “go with the most popular.”
It comes down to what you care about more: official compliance, structured SERP depth, pricing, raw speed, or long-term reliability for your specific use case.
Before we compare these APIs, here’s a quick intro so you know who’s guiding you.
Hi, I’m Josseline, founder of WebAPI Group. I’ve tested all these APIs myself and built one of them, too. So I’ve seen how they behave in real projects, not just in documentation.
In this guide, I’ll break down the features, pricing, and which API is best for what actually matters when you’re building something real.
Let’s get started.

SerpAPI
If you need structured search results straight from Google (and other engines, too), SerpApi is one of the most widely used options out there. It runs searches in real time, solves any challenges behind the scenes, and gives you clean JSON you can use right away.
You ask a query, as you would in a browser, and it returns data you can loop over, store, analyze, or feed into pipelines without extra parsing. Let’s talk about features now.
Features:
Structured Search Data: You get more than just a list of links. SerpApi returns organic results, knowledge panels, answer boxes, news, images, shopping items, local, and map results, all parsed for easy access.
Multiple Engines Supported: Beyond standard Google search, SerpApi can pull results from Bing, Yahoo, DuckDuckGo, and more, all through the same interface.
Flexible Endpoints: There are dedicated endpoints for different search types, such as a faster “light” search that skips extras, or a full search that returns rich snippets and other details.
Localization Controls: You can set country and language parameters so results mimic real users from specific regions without extra setup.
No Scraping Overhead: SerpApi handles proxies, CAPTCHA solving, and browser automation behind the scenes. You make a call, and you get structured JSON back.
Easy Integration: Works with any language that supports HTTP requests, and there are community SDKs for Python, JS, and more to get you started quickly.
Pricing:
→ SerpApi offers a free plan with 250 searches per month, which is enough for testing and small projects.
→ Paid plans start at $25 per month for 1,000 searches.
→ Here’s how the CPM goes lower as you scale:
-
$25/month → 1,000 searches (~$25 per 1,000)
-
$75/month → 5,000 searches (~$15 per 1,000)
-
$150/month → 15,000 searches (~$10 per 1,000)
-
$275/month → 30,000 searches (~$9 per 1,000)
→ Credits don’t roll over and expire within a month, so pick the plan according to the usage.
However, the higher tiers reduce the cost per thousand searches, but they remain at a higher price level and increase hourly throughput. Enterprise plans are available for larger volumes with custom pricing.
Best For:
SEO dashboards, rank trackers, or competitor analysis systems that depend on rich, live search data from Google.
Google Custom Search JSON API
The Google Custom Search JSON API is an official Google Cloud API. It does not return the exact same data you see when you manually search on Google.com.
Instead, it returns results from a Programmable Search Engine (PSE) that you configure. That means the results depend on how your search engine is configured, whether it targets specific domains or the broader web. The control is on your side
Features:
Clean JSON Output: Each response includes basic search result data such as title, link, and snippet. The structure is consistent and easy to parse.
Web and Image Search: You can retrieve web results or image results by adjusting a parameter.
Pagination Support: You can request additional results pages using a “start” parameter.
Pricing:
→ Offers 100 free searches daily.
→ Doesn’t provide subscription plans. Once billing is enabled, you will be charged $5 for every 1,000 queries beyond the free limit.
→ Limit to 10,000 queries per day.
Best For:
-
Basic search integration inside your application
-
A site search feature powered by Google
-
Structured search data without building scraping logic
It is not suitable if you need complete SERP data, ranking position tracking across rich blocks, local results, shopping data, or other advanced Google page elements.
Autom.dev
Autom.dev is a search API built for developers who need fast, structured search results across multiple engines without the hassle of scraping. It provides a single API endpoint that returns real-time search results from various search engines.
The responses are already parsed into clean JSON you can use in apps, tools, or workflows, ideal when you want to search data without building your own scraper or managing bots under the hood.
The API supports not just standard web search results. It also has endpoints for autocomplete suggestions, images, video search results, and news data. That makes it easy to build features such as search-powered dashboards, automated SEO tools, or data feeds that respond in near-real time.
You get this through a unified REST interface with comprehensive documentation. SDKs are available for common languages, and integration is mostly just a matter of passing a query and parsing the returned JSON.
Features:
Multi-Engine Support: Call a single API to pull search results from Google, Bing, Brave, and Perplexity.
Structured JSON Output: Results include titles, URLs, snippets, images, and other standard search fields already parsed for use.
Autocomplete Endpoint: Get real-time suggestion lists for typed queries, useful for search boxes and predictive features.
Image and Video Search Results: Dedicated endpoints return image results and video listings with consistent formats.
Fast Responses: Designed to deliver results in milliseconds with minimal latency for modern apps.
High Uptime: A 99.9% uptime SLA supports reliable production usage.
Easy Integration: Works with HTTP and popular languages (Python, Node.js, PHP, etc.) via REST and SDKs, so you can start testing fast.
Pricing:
→ Free trial with 1000 credits without a credit card
→ Plans start at $50 per month with 50k credits
→ CPM (cost per mile)
-
Starter - $50 for 50,000 credits, $1 CPM
-
Standard - $375 for 500,000 credits, $0.75 CPM
-
Premium - $1,250 for 2.5M credits, $0.50 CPM
-
Ultimate - $3,750 for 12.5M credits, $0.30 CPM
→ The credits do not expire within a year, regardless of the plan you choose.
Best For:
Autom.dev fits developers and teams who want live, structured search data from multiple engines without building or maintaining scraping infrastructure. It’s particularly useful for:
-
SEO and keyword research tools that pull search results in real time
-
Search-assisted features inside products and dashboards
-
Automation workflows that need up-to-date search data
-
Apps that combine web, image, and video search data into a unified view
Because it handles parsing and anti-block challenges for you, it’s a good choice when you want to search data quickly and reliably without heavy maintenance.
Wrap Up
Now you’ve observed the key differences: depth of SERP data, features, pricing models, and use cases of each Google search data scraping API.
If you just need basic links, Google’s API works. If you want rich SERP depth, SerpApi does the job. But if you’re building something that needs multi-engine coverage, predictable scaling, and real CPM advantages, Autom.dev would be the best fit. Just take the free trial with 1000 credits before committing to a paid plan.
