The timelineData array returns dated points with interest values, so you can plot how attention to a keyword rises and falls week over week.
Pass several comma-separated keywords and each timeline point returns a values array aligned to your terms, letting you chart relative interest across up to five topics at once.
Use the location field to scope a query to a market, so the interest curve reflects regional demand rather than a global average.
Beyond the timeline, the endpoint surfaces the queries trending around your terms, helping you catch rising topics before they peak.
Use cases

console.log(data);The Google Trends API for developers — interest over time & regional demand, no scraping
The Google Trends API returns interest-over-time data for up to five keywords at once, with weekly points and regional scoping. Instead of scraping the Trends site or wrestling with its unofficial endpoints, you post your terms and get clean structured data.
It is the demand-signal tool in YepAPI's SEO suite. Pair it with the Keyword Ideas and Content Summary endpoints — one key — to move from spotting a rising trend to planning and validating content around it.
What is a Google Trends API?
A Google Trends API returns search-interest data as structured JSON rather than the interactive charts on the Trends website. You pass one or more keywords and get a timelineData array of dated points, each with a values array of relative interest (0–100) per term, plus averages and related queries. Comparing terms shows which is gaining or fading. The advantage over scraping is stability and clean output. YepAPI serves it at /v1/seo/trends: post comma-separated keywords and a location, and receive the interest timeline ready to chart or threshold.
Build your own trend tracking tool
Build a dashboard that charts interest for a brand against its competitors using the aligned values arrays, or a trend-validation widget that tells a content team whether a topic is rising before they commit. Watch the related/rising queries to auto-surface emerging subtopics for your editorial calendar. Because the data is dated and numeric, you can detect inflection points programmatically and trigger alerts. Feed validated rising terms into the Keyword Ideas API to expand them into a full content plan.
Google Trends API pricing — $0.02/call
Each Trends query is a flat $0.02, comparing up to five keywords in that single call — there is no per-row charge. Polling a set of topics daily for a month costs well under a dollar. Other Trends data providers charge around $0.05 per call with fewer parameters; here you get multi-keyword comparison and regional scoping at two cents, cheap enough to monitor many topics continuously.
Validate seasonal demand before you build
Before investing in content or inventory around a topic, pull its multi-year interest curve and read the seasonality directly from timelineData. A keyword that spikes every November tells you exactly when to publish and when to run ads. Comparing a candidate term against an established one shows whether interest is structurally growing or just briefly hyped — the difference between a durable content bet and a fad. Two cents per check makes this validation routine, not a special project.
