## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability keyword-interest-by-region-google-trends-c83c6eb1
```

Example prompt: Show me which US states have the highest Google Trends interest for 'electric bikes' over the past 12 months so I can figure out where to focus my ad targeting.

## When to prefer this

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.

## Known failure modes

- 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

## How this service works

Google Trends interest by region for one keyword: 0-100 interest per subregion of a country (or per country worldwide), past 7 days to 5 years, in one $0.03 GET. Use when you need where a keyword is searched most, for geo-targeting or local market research. A live call takes up to about 30 s. Bad input is free; upstream errors are not charged.

## 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.
