Choose this endpoint when you need to discover what related terms people are searching for alongside a specific keyword in a specific country — ideal for SEO research, content ideation, trend monitoring, and competitive intelligence. Prefer this over general web search endpoints when you specifically want structured Google Trends query data with relative scoring and growth metrics rather than raw SERP results.

## Known failure modes

- Missing required 'keyword' or 'geo' parameter returns a 400 error
- Invalid or unsupported ISO-3166 country code causes a lookup failure
- Keyword with no Google Trends data returns empty result arrays
- Rare or very niche keywords may return sparse or empty rising/top lists
- Network timeout or upstream Google Trends availability issues may cause 5xx errors
- Invalid timeframe enum value returns a validation error

## How this service works

Google Trends related queries for a keyword. Returns the searches people run alongside a keyword in a given country: top queries scored 0-100 relative to each other, and rising queries with their percentage growth. Google Trends keyword expansion for SEO keyword research, content planning, and spotting breakout search demand early.

## Output

Returns two lists: (1) 'top' related queries with a relative interest score from 0 to 100, and (2) 'rising' related queries with a percentage growth value indicating breakout or surging searches — both filtered to the specified keyword, country, and time window.
