How this service works
Search for Reddit posts by keyword across all subreddits.
Output
Returns a paginated list of up to 20 Reddit posts per page matching the query, including post title, body, author, subreddit, upvotes, comment count, URL, and timestamp. If sentiment analysis is enabled, each post also includes an emotions breakdown (joy, trust, fear, surprise, sadness, disgust, anger, anticipation scored 0–100), dominant emotion, emotional intensity (0–10), and polarity (positive/negative/neutral).
Example use cases

“Find the top posts in r/investing about 'index funds vs ETFs' from the past year, sorted by most commented, first page only.”
Competitive research on Reddit

Technical details
Endpoint
GEThttps://x402.apidirect.io/v1/reddit/posts?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need to search Reddit specifically — across all subreddits or within one — with flexible sorting, time filtering, and optional AI sentiment analysis. Prefer this over generic web search when you want structured Reddit post data with upvote/comment counts and subreddit attribution. Choose the sentiment flag when you need emotional tone analysis on community discussions rather than just raw text.
