为什么Scavio胜出
- Simple API key authentication with no OAuth flow makes integration faster than Reddit's official API
- Structured JSON responses with consistent fields feed directly into sentiment analysis pipelines
- Reddit Official API wins for teams needing real-time data, full comment threads, and vote counts
- Pushshift wins for historical analysis requiring archived Reddit data going back years
- Scavio returns search-indexed results, not raw Reddit API data, so very recent posts may have a delay
