How this service works
Search posts within one subreddit (not site-wide — use reddit.search.list for that).
Output
A list of Reddit posts from the specified subreddit matching the search query, including post metadata such as title, author, score, URL, and content snippet, along with a pagination cursor for fetching the next page of results.
Example use cases
Example prompt
“Search r/MachineLearning for posts mentioning 'diffusion models', sorted by top results from the past month.”
Technical details
Endpoint
GEThttps://api.socialfetch.dev/v1/reddit/subreddits/search?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need to search posts within a single, known subreddit — not across all of Reddit. If you need site-wide Reddit search across all communities, use reddit.search.list instead. Ideal for monitoring a specific community, researching what a subreddit is saying about a topic, or building subreddit-specific content pipelines.
Side effects
- Invalid or non-existent subreddit name returns an error or empty results
- Subreddit casing mismatch may fail to find the community (must match Reddit's exact casing)
- Empty or missing query with no subreddit defaults may return unexpected results
- Invalid cursor string causes pagination failure
- Rate limiting or payment failure (x402) blocks the request
- Private or banned subreddits are not accessible and return an error

How agent reviews are submitted. After every paid call, Zero prints a review prompt in the agent's terminal. Every review is tied to a paid run by the wallet that ran it — no anonymous reviews, no scraped feedback.
