What does the web search API return?

Real Google web results as clean JSON. You always get the organic block with each result's position, title, link, and snippet. When Google shows them for a query, you also get the knowledge graph, people also ask, and related searches, all in one stable schema.

One credit per successful search, however many organic results come back. A search that returns nothing costs nothing. You pay only when a query brings back data, so failed or empty queries never appear on your bill.

Is this real Google or a custom index?

Real Google web search, not a subset you have to configure first. The response reflects what Google actually returns for that query at request time, typically in about 1 to 1.5 seconds.

Can AI agents use it?

Yes. We ship a first-class MCP server plus LangChain, n8n, and CrewAI integrations, and a Clay recipe for no-code. The snippet text comes back inline so an agent can read a result without a second fetch, and you can pair it with the webpage endpoint to pull full page text for RAG grounding.

No. Prepaid credits never expire, so an unused balance stays yours for whenever you need it. The free tier refreshes at 3,000 credits every month with no card required.

THE RESPONSE

What a web search returns

A web search API should feel simple. You send a query, you get Google's results back as data you can parse. That is the whole job of this endpoint, and it returns real Google results in about 1 to 1.5 seconds.

Here is a query for best running shoes, rendered as a flat CSV of the organic block. Every result carries its rank, title, link, and snippet.

position,title,link,snippet 1,Best Running Shoes of 2026,https://runrepeat.com/catalog/running-shoes,Lab-tested picks across road and trail from 200+ models. 2,The 10 Best Running Shoes We Tested,https://www.nytimes.com/wirecutter/reviews/best-running-shoes,We logged 500 miles to find the pairs worth buying. 3,Running Shoe Finder,https://www.brooksrunning.com/shoe-finder,Answer a few questions to match your gait and mileage.

The request is one GET with your key in a header. No SDK required.

curl "https://crustapi.com/v1/search?type=web&q=best+running+shoes" \ -H "x-api-key: YOUR_KEY"

The same call as JSON, ready to hand to an app or an agent:

{ "searchParameters": { "q": "best running shoes", "type": "web" }, "organic": [ { "position": 1, "title": "Best Running Shoes of 2026", "link": "https://runrepeat.com/catalog/running-shoes", "snippet": "Lab-tested picks across road and trail." } ], "peopleAlsoAsk": [ { "question": "Which running shoe is best for beginners?" } ], "relatedSearches": [ "best running shoes for flat feet" ] }

THE SCHEMA

One stable schema, every query

You parse the response once and it keeps working. Organic results are always there. The knowledge graph, people also ask, and related searches appear when Google shows them for that query.

Organicposition · title · link · snippet Knowledge graphtitle · type · attributes · description People also askquestion · snippet · link Related searchesquery terms

It is the same clean JSON shape developers already reach for, so if you have code written against a SERP API or a Google Search API, moving over is mostly a base-URL swap.

FOR AGENTS

Built for AI agents and RAG

The snippet text comes back inline with every result, so an agent can read and reason over a search without a second fetch. When you need the full page body for grounding, pair a web search with our webpage endpoint to pull clean article text from any result link.

The same endpoint is wired into the tools agents already run. We ship a first-class MCP server, plus LangChain, n8n, and CrewAI integrations, and a Clay recipe on the no-code side. Point the tool at your key and an agent can search Google mid-task, then keep going.

PRICING

Pay per successful search

One credit buys one successful search, however many organic results come back. A query that returns nothing costs nothing, so a bad query never lands on your bill.

The entry pack works out to $1.96 per 1,000 searches, and that drops to $0.40 per 1,000 on the largest pack. For deeper cost math, see our SERP API breakdown.

WHERE WE FIT

How it compares

The closest first-party option is Google's Custom Search JSON API. It is solid for a narrow job, but it does not search all of Google, and it caps you by the day.

	Custom Search JSON API	CrustAPI
What it searches	A search engine you configure	All of Google web search
Price per 1,000	$5 per 1,000 queries	$1.96, to $0.40 at scale
Daily cap	10,000 queries a day	None
Zero-result query	Counts against your quota	Free, you pay only on success
Free tier	100 queries a day	3,000 a month, no card

WHEN THEY WIN

You only search sites you own: if you just need results from a handful of domains you control, Google's Custom Search JSON API does that natively, and its free 100 queries a day may cover you with nothing extra in the stack.

On legality, US courts have repeatedly sided with collecting public, logged-out pages, while a site's terms restrict automated access on their side. We handle the collection, and what you get is data that is public for anyone to see.
