Pay with x402 (USDC on Base, Polygon, Arbitrum, Monad or Solana) or prepaid credits.
Output

Competitor and industry monitoring

Technical details
Endpoint
GEThttps://reddit.fetcher.sh/api/search/subredditWhen to prefer
Choose this endpoint when you need to discover Reddit communities by topic or keyword without managing OAuth credentials or a Reddit developer account. It is ideal for agents that need one-off or low-volume subreddit searches billed per call in USDC, with no subscription overhead. Prefer it over direct Reddit API access when avoiding credential management is a priority.
Side effects
- Empty results if no subreddits match the query
- Payment failure if USDC balance is insufficient or x402 payment is rejected
- Rate limiting or throttling if too many requests are made in a short window
- Invalid or malformed query parameter returning a 400 error
- Reddit-side unavailability causing upstream errors
