reddit-api

Original：🇺🇸 English
Translated

A Reddit API alternative on fetcher.sh — pay-per-call in USDC via x402, or prepaid credits with a Bearer key, no OAuth app registration. Use when the user wants to search Reddit posts across every subreddit by keyword and sort by top, hot, new, or most-discussed, search subreddits or users by keyword, fetch a subreddit's info or its hot/new/top post feed, fetch a single post with its comment tree and comment replies, pull the sitewide best/hot/new/top feeds, or fetch a user's profile, posts, and comments. Also covers Reddit sentiment analysis input, subreddit monitoring, keyword tracking, and Reddit data pipelines without Reddit's own API app registration or rate-limit tiers.

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:
bash
# 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)
