Limits and tips

• Reddit may rate-limit or block direct requests. Keep useApifyProxy enabled for the most reliable runs.
• Use low maxPosts values for frequent monitoring and scheduled runs.
• Duplicate posts from overlapping sources are deduplicated within a single run.
• NSFW posts are skipped unless includeNsfw is enabled.

Legality

This actor is designed for publicly available Reddit content. Use it responsibly, respect privacy, and make sure your use case complies with Reddit's terms, Apify's terms, and applicable laws.

FAQ

Can I monitor multiple subreddits? Yes. Add several names to subreddits and set a shared maxPosts limit.

Can I search Reddit by keyword? Yes. Use searchQueries for keywords, brands, or phrases.

Why did my run return few posts? Reddit availability, filters, and rate limits can affect results. Try a broader query, another sort, or a larger maxPosts value.
