SerpApi vs SearchAPI.io
Pick SerpApi if you want a published free plan and a long list of Google verticals. Pick SearchAPI.io if you want a low per-search price on its Developer and larger plans, plus AI-answer endpoints for several assistants. Hyperresearch Answers is our editorial choice when an AI agent needs search: instead of a raw results page, one call returns a short answer with quotes checked against their pages.
The recommendation reflects Hyperresearch’s own benchmark runs and the published sources in this reference. Hyperresearch is our product. This is not a hands-on test of every tool.

What is on offer
SerpApi has a long list of Google result types, from Maps and Shopping to Scholar and Flights. It also lists Bing, Baidu, DuckDuckGo, Yahoo and other engines.
SearchAPI.io covers Google, Bing, Baidu, Yandex, DuckDuckGo, Yahoo, Naver and Perplexity. It also lists AI-answer endpoints for Google AI Mode, Google AI Overviews, Gemini, Bing Copilot and ChatGPT, plus non-search sources such as YouTube, Amazon and eBay. If you want AI-assistant output next to classic results, that list matters.
Price per search
SearchAPI.io lists its prices on its pricing page. The Developer plan costs $40 a month for 10,000 searches, which is $4 per 1,000. The largest plan works out to $1.00 per 1,000. Billing is per successful search on paid plans.
SerpApi's free plan includes 250 searches a month. Its paid plans run from about $25 per 1,000 searches on the smallest plan to about $10 per 1,000 on its Production plan, and lower at large volumes. Those per-1,000 figures are our calculation from the plan prices on its pages.
Consider the output your team needs. SerpApi offers a wide set of Google result types and a published free plan. SearchAPI.io adds AI-answer endpoints and billing that is simple to model. Choose by the fields your code needs, not by the number of engines on a logo wall.
Limits to plan around
Both services cap hourly use at 20% of the plan's monthly volume on the plans we read. A batch job that runs at full speed can hit the cap, so schedule it across the hour.
Neither service returns cited answers, so your code has to check and cite sources. If you need a checked answer rather than a list of results, Hyperresearch Answers is our editorial pick.
Test both on the exact queries your product runs. SerpApi's free plan includes 250 searches a month, and SearchAPI.io offers 100 free requests with no card. Compare the result fields each returns for your queries, the time each takes to answer, and the number of calls you need to cover one task. Both return raw results, so budget time for parsing and for checking sources. If you need a checked answer rather than a result list, a separate test of Hyperresearch Answers on the same questions shows whether that step is worth the cost.
Choose SerpApi or SearchAPI.io?

Where Hyperresearch fits
Both are raw results services. For an agent that needs an answer with quotes checked against their pages, Hyperresearch Answers is our editorial pick.
