Google opened applications for an alpha version of its Google Trends API on 24 July 2025, giving selected developers the first programmatic access to scaled search-interest data.
Alpha launch details
The company will onboard testers in waves as it refines the service. Interested developers can apply to be an alpha tester.
- Access: limited alpha release. Full documentation is available at the Google Trends API is here page.
- Data window: rolling 1,800 days (about five years).
- Time granularity: daily, weekly, monthly and yearly aggregates.
- Geography: region and sub-region breakdowns aligned with the ISO 3166-2 standard.
- Scaling method: results are consistently scaled across multiple requests but do not reveal absolute query volume, a concept Google calls search interest.
- Suggested use cases: academic research, newsroom trend tracking and marketing planning.
The announcement was posted by Daniel Waisberg and Hadas Jacobi from the Google Trends team.
Background
Since 2006, Google Trends has offered public, web-based visualisations of search interest through the Trends website. Each chart on the site scales results independently from 0 to 100, making it hard to combine data from multiple queries.
The new API applies a single scaling approach, allowing analysts to merge results across many calls without recalculating baselines. Google has not announced a general release date and will use feedback from alpha testers to shape broader availability.
