Google Autocomplete Keyword Suggestions API

Turn seed phrases into localized Google Autocomplete suggestions for SEO research, content planning, paid-search discovery, and product-language analysis. Query one or many seeds, optionally expand them by alphabet suffixes or common question prefixes, and export deduplicated results as clean records.

No API key, login, browser automation, or paid proxy is required.

What data can I extract?

• Original seed and exact request query
• Suggested keyword phrase and its rank in the response
• Expansion suffix or question prefix that produced it
• Language and country localization
• Reproducible source endpoint URL

Each row represents one unique suggestion. Duplicate phrases found through several expansions are emitted once.

Input example

{
  "queries": ["artificial intelligence", "workflow automation"],
  "language": "en",
  "country": "US",
  "expansion_mode": "questions",
  "max_items": 100
}

Output example

{
  "seed": "artificial intelligence",
  "request_query": "how artificial intelligence",
  "suggestion": "how artificial intelligence is changing the world",
  "rank": 1,
  "expansion": "how",
  "language": "en",
  "country": "US",
  "api_url": "https://suggestqueries.google.com/complete/search?client=firefox&q=how+artificial+intelligence&hl=en&gl=US"
}

Common use cases

• Long-tail SEO and content-brief research
• Discovering customer questions and search language
• Keyword clustering and editorial planning
• Localized keyword ideation across countries and languages
• Building suggestion datasets for agents, spreadsheets, and BI tools

Use with AI agents and MCP

The flat schema lets an agent expand a topic, group suggestions by intent, compare localized phrasing, or generate a content plan without operating a browser. Set a small max_items for interactive tools and an expansion mode for broader research.

Pricing and cost control

Output is billed per result at $0.0005 per result (about $0.50 per 1,000 results), plus a $0.0005 Actor-start charge billed once per gigabyte of memory at run start. Use max_items and expansion_mode to cap both request volume and charges. The price shown on the Apify Store listing is authoritative.

Reliability

The Actor calls the public suggestion endpoint directly, retries temporary transport, rate-limit, and service failures, validates the response shape, deduplicates suggestions, and stops at the requested limit. Persistent upstream failures are reported rather than returned as false empty results.

Limitations and responsible use

• Suggestions are dynamic, localized, and can change between runs.
• Autocomplete is a discovery signal, not verified search-volume data.
• Country and language hints influence results but do not guarantee a particular phrase.
• Large expansion jobs make several requests and should use conservative limits.
• Follow applicable Google terms and use the data responsibly.

FAQ

Does this return search volume?

No. It returns phrases suggested by Google Autocomplete and their response order, not monthly search counts.

What does alphabet expansion do?

It requests the seed followed by each letter from a through z, which can expose additional long-tail phrases.

Can I search several seeds at once?

Yes. Add them to queries; max_items applies across the whole run.

Are duplicate suggestions billed twice?

No. The Actor deduplicates suggestion text before saving results.
