How this service works
Search volume, CPC, competition, keyword difficulty, intent, keyword ideas and Google Trends, paid per call over x402 (USDC on Base). No account, no API key.
Output
A JSON object containing: a time-series array of {date, value} points where value is Google's relative interest index (0–100, with 100 = peak of the period); market metadata (country code, location name, location code); granularity (daily or weekly depending on window); the source (Google Trends via DataForSEO); a 'see_also' hint pointing to the related-queries endpoint; and request metadata (queried_at, dataAsOf, request_id).
Example use cases
Seasonal demand check for e-commerce
“What does the search interest trend look like for 'winter boots' in the UK over the past 12 months? I want to know if there's a clear seasonal spike and when it peaks.”
New market viability research
“Can you check Google Trends interest for 'meal kit delivery' worldwide over the past 5 years? I'm trying to figure out if overall demand is growing or plateauing.”
Content timing for a blog post
“I'm writing a post about 'tax filing tips' — can you get me the past 90 days of Google Trends data for that keyword in the US so I know if search interest is currently rising?”
Technical details
Endpoint
GEThttps://keywords.duoleads.com/v1/trend?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a time-indexed interest signal for a single keyword — for seasonality analysis, demand direction, or trend monitoring. It is ideal when you want the raw dated series (daily or weekly) to plot or analyze over time, rather than a point-in-time volume number. Prefer the search-volume endpoint instead when you need absolute monthly search volume, CPC, or keyword difficulty. Use this alongside the related-queries or by-region endpoints for fuller keyword intelligence.
Side effects
- Bad or unrecognized keyword input returns a free (uncharged) error response
- Upstream DataForSEO/Google Trends errors are charged but may return empty or partial series
- Invalid country code (not ISO 3166-1 alpha-2) causes a validation error
- Keyword shorter than 2 or longer than 100 characters is rejected
- Live call latency can reach ~30 seconds; timeouts may occur in constrained environments
- The most recent data point may be marked 'partial: true' as the period is incomplete
