Why Scavio Wins
- Zero GCP dependency and zero infrastructure setup. Vertex AI Search requires Google Cloud project, data store, and IAM configuration; Scavio requires one API key.
- Five-platform web search replaces Vertex's web grounding for agent use cases. Google, Amazon, YouTube, Walmart, and Reddit data through one endpoint.
- MCP integration provides agent-native search without custom connectors. Vertex AI Search integration requires GCP client libraries; Scavio MCP is one config line.
- $0.005/credit is transparent pricing. Vertex AI Search pricing depends on document count, query volume, and GCP compute, making costs hard to predict.
