Example prompt: Can you pull Google Trends data for 'electric vehicles' in the US over the past 90 days and show me the interest over time plus any related rising queries?

## When to prefer this

Choose this endpoint when you need structured Google Trends data programmatically without a Google API key or account setup, and want to pay per-call with no subscription. It is ideal for agents that need on-demand trend lookups, regional interest comparisons, or related query discovery for one or more search terms. Prefer this over building your own scraper or managing API credentials when lightweight, pay-as-you-go trend intelligence is sufficient.

## Known failure modes

- Invalid or unsupported query string returns empty results
- Unsupported geo or language code causes a 400-level error
- Very low-volume search terms may return no interest-by-region data unless include_low_search_volume is set to true
- Rate limiting or payment failure (402) if USDC payment is not properly attached
- Overly broad date ranges or unsupported date format strings return errors
- Requesting an unsupported data_type value causes malformed response
