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 listing each subregion (or country, for worldwide) with its region name, region code, and relative interest score (0–100, where 100 = highest-interest region). Also includes the market context (country code, location name), data source attribution, the timeframe queried, timestamp, request ID, count of regions excluded due to insufficient data, and a see_also hint pointing to the trend-over-time sibling endpoint.
Example use cases
Regional ad targeting for new product
“Which US states are searching the most for 'standing desk' over the past 90 days? I want to know where to concentrate our Google Ads budget.”
International market entry research
“I'm thinking about expanding into Europe — can you check which countries worldwide have the highest Google Trends interest in 'meal kit delivery' over the past 5 years?”
Local SEO content strategy
“Pull the Google Trends interest by region in Germany for the keyword 'elektroauto' over the past 12 months — I want to see which German states are most engaged so we can tailor our blog content.”
Technical details
Endpoint
GEThttps://keywords.duoleads.com/v1/interest-by-region?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need to understand the geographic distribution of search interest for a keyword — e.g., deciding which regions to geo-target, identifying local demand hotspots, or prioritizing markets for expansion. Prefer this over the trend-over-time endpoint when the question is 'where' rather than 'when'. For a global view, omit the country parameter; for subregional breakdown, specify a country code.
Side effects
- Invalid or unsupported country code returns an error (no charge)
- Keyword shorter than 2 or longer than 100 characters rejected as bad input (no charge)
- Upstream DataForSEO / Google Trends outage may return an upstream error (charged)
- Very niche keywords may return few or no regions due to insufficient data
- Requests can take up to ~30 seconds due to live upstream call; timeouts possible
