"""Standalone Reddit public JSON search module.
|
||||
|
||||
Searches Reddit using the free public JSON endpoints (no API key required).
|
||||
Promoted from last-resort fallback to robust primary free path.
|
||||
|
||||
Endpoints:
|
||||
- Global: https://www.reddit.com/search.json?q={query}&sort=relevance&t=month&limit={limit}
|
||||
- Subreddit: https://www.reddit.com/r/{sub}/search.json?q={query}&restrict_sr=on&sort=relevance&t=month
|
||||
|
||||
Handles 429 rate limits with exponential backoff, HTML anti-bot responses,
|
||||
network timeouts, and missing subreddits.
