Endpoint
GEThttps://x402.apidirect.io/v1/reddit/subreddits?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need to discover or enumerate Reddit communities by topic keyword, particularly for market research, community monitoring, content strategy, or identifying niche audiences. Prefer it over Reddit user search when the goal is finding communities rather than individuals, and over post-search endpoints when you want to identify the communities themselves rather than specific content within them.
Side effects
- Empty results if no subreddits match the keyword
- Query exceeds 500 character limit returning a validation error
- Pages parameter outside 1-10 range returning a validation error
- Reddit rate limiting or availability issues causing request failure
- Payment failure if USDC balance is insufficient
