Reddit API
Reddit data on demand: cross-subreddit post search, subreddit and user search, subreddit info and feeds, single posts with full comment trees, sitewide best/hot/new/top feeds, and user profiles/posts/comments — one plain HTTP GET per call, paid as you go. No OAuth app registration, no client ID/secret pair, no Reddit API rate-limit tier.
Base URL: https://reddit.fetcher.sh
Authentication
Two ways to pay, same data — full mechanics in the `fetcher` skill:
# 1. Prepaid credits (recommended — get a key at https://fetcher.sh/topup
# or via POST /api/credits/topup, see the fetcher skill)
export FETCHER_API_KEY="bby_live_xxxxxxxxxxxx"
curl -H "Authorization: Bearer $FETCHER_API_KEY" \
"https://reddit.fetcher.sh/api/search/post?keyword=hello"
# 2. x402 pay-per-call — omit the header; a GET with no payment returns 402
# with machine-readable payment requirements (USDC on Base, Polygon,
# Arbitrum, Monad, or Solana). @x402/fetch signs and retries automatically.Every response is { "status": number, "message": string, "data": ... }; the HTTP status mirrors status.
Endpoints (15 — all GET, $0.002/call)
| Endpoint | What it returns |
|---|---|
/api/search/post | Posts across every subreddit matching a keyword |
/api/search/subreddit | Subreddits matching a keyword |
/api/search/user | Users matching a keyword |
/api/subreddit/{name} | A subreddit's info |
/api/subreddit/{name}/posts | A subreddit's post feed |
/api/post/{id} | A single post |
/api/post/{id}/comments | A post's comment tree |

/api/user/{username}/posts | A user's posts |
/api/user/{username}/comments | A user's comments |
{id} / {name} / {username} are path parameters. Optional sort / cursor reorder and paginate; keyword (search) is required where it appears.
