Google Autocomplete API

A Google Autocomplete API that returns the search box's own suggestions for one seed. Send a partial query, a country and a language, and get back every completion Google would offer, each with its relevance score and type flag — billed per suggestion delivered.

What a Google Autocomplete API does

Autocomplete is Google telling you, live, which continuations it considers likely for a prefix — no volume attached, but not a model either. This endpoint makes the single call to that surface and returns the raw list: the suggestion, Google's relevance ordering and the type (QUERY, ENTITY…), exactly as the box would render them.

Two things get built wrong here. The endpoint is defended per IP, so a bare script is throttled within a handful of calls and the exit rotation is the part you are really paying for. And this is search-query autocomplete, not the Places address autocomplete developers often land on by mistake — it completes what people search, not postal addresses. For a–z, question and comparison expansion of a seed, the keyword_ideas collector wraps this same primitive.

What one suggestion looks like

Every delivered suggestion carries these fields. Nullable means the source did not publish it — the field stays empty instead of being guessed.

Field	Type	What it holds
`rank`	integer	Suggestion order as Google returns it.
`suggestion`	string	The suggested query.
`relevance`	integer · nullable	Google's relevance score, when provided.
`type`	string · nullable	Suggestion kind (QUERY, ENTITY…), when provided.
`seed`	string	The seed that produced this suggestion.

Inputs

The whole request. Anything you leave out falls back to the default shown in the catalog.

Input	Type	Required	What it does
`query`	string	yes	The partial query to complete, e.g. "proxy ser".
`country`	string	no	ISO 3166-1 alpha-2 code — proxy exit geo and Google locale (gl). Omit for the default pool.
`lang`	string	no	Interface language (hl), e.g. en, it, de.
`max_results`	integer	no	How many suggestions to deliver at most (1–20). You pay only for delivered suggestions.

Pricing

Google Autocomplete API pricing

$0.0002 per delivered suggestion. A run that delivers nothing costs nothing: blocked pages, challenges and retries are on us, and the $2 monthly allowance covers about 10,000 suggestions before you spend anything.

Integration

One POST, typed rows

Base URL https://api.quanticdata.io/v1, Bearer auth, the same key as every other Data API. Endpoint: POST /v1/scraper/collectors/google_autocomplete/run.

curl -X POST https://api.quanticdata.io/v1/scraper/collectors/google_autocomplete/run \
  -H "Authorization: Bearer $QD_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{"query":"web scraping","country":"us","lang":"en","max_results":10}'

import requests

r = requests.post(
    "https://api.quanticdata.io/v1/scraper/collectors/google_autocomplete/run",
    headers={"Authorization": f"Bearer {QD_API_KEY}"},
    json={
        "query": "web scraping",
        "country": "us",

        "max_results": 10
    },
    timeout=120,
)
for row in r.json()["payload"]["results"]:
    print(row)

const res = await fetch(
  "https://api.quanticdata.io/v1/scraper/collectors/google_autocomplete/run",
  {
    method: "POST",
    headers: {
      Authorization: `Bearer ${process.env.QD_API_KEY}`,
      "Content-Type": "application/json",
    },
    body: JSON.stringify({"query":"web scraping","country":"us","lang":"en","max_results":10}),
  },
);
const { payload } = await res.json();
console.table(payload.results);

What people build with the Google Autocomplete API

Three shapes of work this endpoint was designed around.

Live suggestion UIs

Back your own search box with Google's completions for a country without exposing an internal endpoint to the browser.

Seed validation

Check what Google actually offers for a term before it goes into a content brief or an ad group.

Entity discovery

Read the type flag to separate plain queries from entity suggestions when mapping a topic.

Google Autocomplete API versus rolling your own

The differences that actually cost time when you build this in-house.

	DIY scraper	This collector
What you send	A partial query plus an endpoint you keep unblocked	A seed, a country, a language
Autocomplete kind	Places address autocomplete, by mistake	Search-query suggestions, as the box shows them
Scale	One seed at a time	This primitive, or keyword_ideas for full a–z expansion

FAQ

Questions we get about the Google Autocomplete API.

Something else? Ask us →

Do I need a Google API key?

No. You send a seed and a country to the collector; the call to Google's endpoint, the exit and the parsing are handled for you, and you are billed per suggestion returned rather than against a key quota.

Is this the same as Places address autocomplete?

No, and it is a common mix-up. Google's Places API completes postal addresses; this completes search queries — what a person types into the search box. City and street completion is a different product.

How is this different from the keyword research API?

This is the single-seed primitive: one seed, one list. The keyword research API wraps it and expands a seed across the alphabet, question words, prepositions and comparisons, de-duplicating across all of them. Use this when you want one clean suggestion set, that when you want the whole long-tail.

Does it return search volume?

No. Autocomplete carries a relevance ordering, not a volume figure, so the collector returns the rank and Google's relevance score and never a made-up number of searches.

Is there a free Google Autocomplete API?

Every account gets $2 of credit every month with no card, which is about 10,000 delivered suggestions on this endpoint at $0.0002 each. It renews monthly, and a run that delivers nothing is never billed — so a failed or blocked attempt does not eat the allowance.

How much does one run cost?

Multiply the rows you actually receive by $0.0002. A run capped at 20 suggestions — the maximum for this collector — costs $0.004 if every row comes back, and less when the source has fewer. Volume tiers take up to 30% off, and GET /v1/scraper/collectors returns the price your key actually pays.
