A Google Trends call for trail running shoes in the US: the real interest-over-time curve of the last 12 months in the middle, with its peak at 100, and the trends JSON with keywords, timeframe today 12-m, geo US and interest_over_time. The answer came from the plain page: $0.0009 per search, $0.002 when rendered. — Google Trends as JSON: 12 months of interest for a keyword in a country, 100 at the peak.

What you get

A series, or a list of trending searches.

Fields of the Trends answer
Field	What it holds
`trends.keywords`	The keywords compared
`trends.timeframe`	Period ("today 12-m")
`trends.geo`	Country
`trends.interest_over_time[].date`	Week or day
`trends.interest_over_time[].timestamp`	Unix time
`trends.interest_over_time[].value`	Interest, 0 to 100
`trending.searches[].query`	A search trending now (no keyword sent)
`trending.searches[].approx_traffic`	Traffic band ("100+")
`trending.searches[].articles`	News articles about it

Interest is relative, as on trends.google.com: 100 is the peak of the period, not a number of searches.

The answer is the usual envelope: payload.trends holds the list above, payload.search_metadata says which tier answered and how long it took.

Parameters

Which keyword, where.

Request parameters for search_type: trends
Parameter	Meaning
`query`	The keyword; leave it out for the searches trending now
`country`	Proxy exit and Google locale (`gl`), ISO code: us, gb, de, it…
`lang`	Interface language (`hl`): en, de, it…
`device`	`desktop` (default), `mobile`, `ios` or `android`

Every parameter, for every vertical, is in the API reference.

Price

Per search, nothing monthly.

A successful search costs $0.0009 when Google's plain page answers and $0.002 when the rendered page is needed; search_metadata.path in the answer says which one you got. In our test on 30 October 2026 the call answered from the plain page in 5.18 seconds.

Failed searches are not charged. There is no subscription: a $2 free credit every month covers the first calls, then you top up your balance by card, PayPal or crypto.

If you would rather pay per trend than per search, the Google Trends — trending now collector returns the same data at $0.0005 per delivered trend (up to 20 per run), with no pagination to handle.

Every price per search and per vertical: SERP API pricing.
