Search demand data APIs: Google Trends data, extracted as an API
Search demand data APIs return what people search for and when, as structured rows a program can read. Kwerix builds them as Apify Actors paid per result, with no subscription: the first is the Google Trends API, which extracts interest, regions, breakout queries, seasonality and Trending Now for any keyword list.

What are search demand data APIs?
Search demand data APIs are programmatic sources of search behavior: how interest in a term changes over time, where it is searched and which related searches grow around it. Each Kwerix API runs as an Actor on Apify, charges per result row and returns the same fields to Python, JavaScript, plain HTTP and AI agents through MCP.
