How this service works
Google Trends interest over time or by region for one or more terms, as JSON timeline data. 5 credits ($0.005000 USDC) for this request; failed requests are never settled.
Output
A JSON object containing interest_over_time with timeline_data arrays, each entry including a date range and per-query interest values (0-100 scale), and optionally regional breakdown data with geographic interest scores per query term.
Example use cases
Competitor brand interest comparison
“Get me Google Trends interest over the last 5 years for 'Pepsi' and 'Coca-Cola' worldwide so I can see how their search popularity has shifted.”
Regional keyword demand research
“Pull Google Trends data for 'solar panels' broken down by US state for the past 3 months — I want to see which regions have the most search interest.”
YouTube trend tracking for content planning
“Check Google Trends for 'vegan recipes' and 'keto diet' on YouTube search over the past year — I want to know which topic has been more popular for video content.”
Technical details
Endpoint
GEThttps://api.fastaf.co/x402/v1/trends?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need programmatic access to Google Trends interest data — either over time or by geographic region — for one or more search terms, especially when you want JSON-formatted output ready for analysis, visualization, or downstream processing. It supports comparison of up to 5 terms, multiple search properties (web, YouTube, news, images, shopping), flexible date ranges, and regional granularity down to city level.
Side effects
- Invalid or unsupported region code returns an error or empty data
- More than 5 comma-separated query terms exceeds upstream Google Trends limit
- Invalid date range format causes a 400 or empty response
- Empty geo value (instead of omitting it) may cause upstream errors
- Unknown category ID returns default all-categories data or an error
- Payment not settled if request fails — 5 credits only charged on success
