Reddit Trends API

Reddit's own API gives you posts and comments. It does not give you a normalized time series showing how discussion volume around a keyword has changed over the past five years. That distinction matters when the question is not "what did people say" but "how much are people talking about this, and is it growing."

Trends MCP answers that question via REST.
