Key Engineering Takeaways (TL;DR)

  • ✓Combine high-intent buyer phrases ('alternative to', 'migrating from', 'recommend a tool for') with ?sort=new&since=<last_seen_utc>.
  • ✓Empty search polls (0 matching posts) deduct 0 Credits on RedditDataAPI.io, making 5-minute cron monitoring virtually free.
  • ✓Enrich leads automatically with GET /v1/subreddit/info to check community self-promotion rules before replying.
