Why it exists

Reddit trend data, without the plumbing

Reddit is where niche demand shows up first: people describe problems in their own words months before those phrases become search keywords. Tracking discussion volume over time turns that into a measurable signal instead of anecdote.

Since Reddit's API pricing changes, programmatic access means OAuth apps, rate limits and terms-of-service review. Trends API handles collection and normalization; you query a subreddit or topic and get back a 0-100 series you can compare against search and social sources.

FAQ

Common questions

What Reddit data does Trends API provide?

Subreddit subscriber counts and discussion volume as normalized time series, growth percentages over 3M/6M/12M/5Y, plus live Reddit Hot Posts and r/worldnews feeds.

Do I need to register a Reddit app?

No OAuth, no client ID, no redirect URIs. Your Trends API key is the only credential.

Can I track a stock ticker?

Yes. Pass the ticker or company name as the keyword to get discussion volume over time, a common alternative-data input for equity research.

How does the 0-100 score work for Reddit?

Each series is rescaled against its own history: 100 is the peak of the requested window. That makes Reddit discussion volume directly comparable to Google search interest or TikTok hashtag volume.

How often does the hot-posts feed update?

Continuously through the day. Every response includes a timestamp so you know exactly how fresh it is.
