Google Trends API: Reliable Interest, Regions & Related Queries

Google Trends data that comes back: interest over time, interest by region, and related queries and topics, for up to 200 keywords a run, compared in groups of up to 5 as on Google Trends. Each group is retried on a data-source error, and a group that still fails comes back as a clear error row, not charged, instead of failing the whole run.

Tested for reliability: 20 of 20 runs succeeded in testing on 2026-10-23, from 1 keyword to 200 (309 keywords in all), across all 5 properties, all 7 time ranges and 7 locations. No keyword failed.

Simple pricing: $0.045 per keyword checked, nothing per run start or per row. Checking 100 keywords costs $4.50.

Who it is for

• SEO and content teams choosing topics and timing posts by seasonal interest.
• Market researchers and analysts comparing brands, products or categories over time and by region.
• AI agents and automations that need a trends signal as plain JSON.

What you get

One row per keyword group:

Field	What it means
keywords	The keywords compared in this row (1 to 5).
status	ok, or failed with an error (not charged).
interestOverTime	One point per step of the period: date (its start), dateTo, values (each keyword, 0 to 100) and partial (Google marks the step as incomplete, usually the latest).
averageInterest	Each keyword's average interest over the period.
interestByRegion	Interest by region: geoId (for example US-TX), geoName, and values per keyword.
relatedQueries	For a keyword checked on its own: the top and rising related searches, each {title, value}.
relatedTopics	For a keyword checked on its own: the top and rising related topics, each {title, topicType, value}.
googleTrendsUrl	The same comparison on Google Trends.
location, language, property, timeRange	What was checked.
source, checkedAt	"Google Trends data via DataForSEO", and when it was checked (UTC).

Interest is relative, as on Google Trends: 100 is the highest point of any keyword in the group during the period, and 0 means too little data. Compare numbers within a row, not across rows. Top related values are on the same 0 to 100 scale; rising values are the increase in percent, or "Breakout" for a very large one.

Example output

One real row from a test run on 2026-10-23: "chatgpt" in the United States over the past 12 months, with every data type on. The timeline is cut to its first and last weeks (it has 53), and the regions and related lists to their first few. Keywords are search terms only; AppGild is not affiliated with the brands they name.

Input

• Keywords: one per line, each checked on its own. This is also how you get its related queries and topics.
• Comparison groups: one comparison per line, up to 5 keywords separated by commas (for example chatgpt, gemini, claude).
• Location: a country by name ("United States", "United Kingdom", "Germany"), a US state by name or code ("Texas", "TX"), or "Worldwide". Default: United States.
• Time range: past day, 7 days, 30 days, 90 days, 12 months (default) or 5 years, or custom start and end dates.
• Property: web search (default), news, images, shopping or YouTube.
• Data: interest over time (on by default), interest by region, related queries, related topics.
• Language: a language code (default en).

Use from an AI agent / MCP

Agents can call this Actor as a tool through Apify's MCP server (https://mcp.apify.com) or the Apify API, by its ID appgild/google-trends-api. Every input has a default except the keywords themselves, and every row is plain JSON with the fields above.

{
  "keywordGroups": ["chatgpt, gemini, claude"],
  "keywords": ["electric bike"],
  "location": "United States",
  "timeRange": "past_12_months",
  "interestOverTime": true,
  "interestByRegion": false,
  "relatedQueries": true,
  "relatedTopics": false
}

The results are the run's default dataset, one row per keyword group. The run's summary (keywords checked, failed and not checked, with its status message) is the OUTPUT record in the run's key-value store.

Pricing

Pay per result: $0.045 per keyword checked (keyword-checked). A comparison group of 5 keywords is 5 checks. Twelve months of interest for 50 keywords is 50 checks, $2.25. There is no charge to start a run and none per row. Apify platform usage is billed to you as well.

You are charged only for keywords whose data came back. A group that fails at the data source after its retries is saved with its error and is not charged. Set a maximum charge on the run and the Actor stops before it would go over it.

Limits

• Up to 200 keywords per run, and up to 5 in a comparison group. A longer group is split into groups of 5; a longer list is cut, and the run's status message says how many were not checked or charged.
• Related queries and topics come per keyword: Google gives them for one keyword at a time, so they are filled for keywords checked on their own and left out of comparison groups.
• A run of up to 20 groups is checked right away, in seconds per group. A run with more than 20 groups goes to the data source's standard queue, which takes minutes instead of seconds, and its status message says so.
• Daily capacity: the Actor has a daily data budget shared by all its users. When it is used up, runs stop cleanly with a status message, charge nothing more, and work again after 00:00 UTC.
• Google Trends works from a sample of searches, so the same check repeated later can differ slightly.
• Rising lists for a narrow location or period can include odd or spam-like searches. They are reported as Google returns them, without filtering.

Terms of use
