Why Scavio Wins
- Polygon.io is the right choice if you need actual stock data (prices, volume, fundamentals). Scavio is a search API, not a financial data API.
- Reddit's official API provides the most complete data with real-time streaming. If you can get approved and stay within rate limits, it is the best source for Reddit sentiment.
- Scavio's advantage is combining Reddit threads + Google News in one API call. A sentiment tracker that checks both sources gets a more complete picture.
- The Reddit lawsuit context matters: Anthropic, SerpAI, and Oxylabs are being sued for scraping. Using a structured API (Scavio or Reddit official) avoids this legal risk entirely.
- For hobby stock trackers, the free tiers matter: Scavio 500/mo + Serper 2,500 free = a functional sentiment tracker at $0/mo for low volume.
