Why Scavio Wins
- Amazon + Walmart price data from one API at $0.005/credit. Keepa is Amazon-only; CamelCamelCamel has no API. Scavio covers two major marketplaces with room for more.
- Reddit endpoint surfaces real deal discussions that price trackers miss. Find products people are actually looking for deals on, not just products with price drops.
- MCP integration lets AI agents monitor prices autonomously. Build deal-finding agents that compare Amazon and Walmart prices, check Reddit for deals, and alert on opportunities.
- Google search adds price comparison pages and deal aggregators. Get the full pricing landscape, not just direct marketplace prices.
