Why Scavio Wins

  • Five-platform grounding provides cross-source verification. An agent can check a claim on Google, verify via Reddit discussions, cross-reference with YouTube content, and check marketplace data for consistency.
  • Hosted MCP integration means agents connect directly without proxy infrastructure. LangGraph, Claude, and custom agents call one endpoint and receive structured grounding data from five platforms.
  • Structured JSON keeps grounding token-efficient. Unlike raw HTML scraping, Scavio returns only the fields agents need for verification, keeping context windows focused on relevant information.
  • At $0.005/credit for five-platform grounding vs Tavily at $200/mo for web-only, Scavio provides broader verification at lower cost. Multi-source grounding reduces hallucination risk more effectively than single-source.
