AI agents in 2026 are the primary consumers of search APIs. An agent might run 5-50 searches per task across multiple platforms, making per-query cost and multi-platform coverage critical. The best search API for agents must work as an MCP server or function-calling tool, return structured JSON that fits cleanly into tool call responses, cover multiple platforms so the agent can route by context, and price affordably for high-volume agent workloads.
Scavio wins for AI agents because it offers an MCP server with 11 auto-discovered tools, covers 5 platforms under one key, returns structured JSON designed for tool call responses, and costs $0.005/query so multi-step agent runs stay affordable.

Why Scavio Wins
- MCP server at mcp.scavio.dev/mcp exposes 11 tools that any MCP-compatible agent discovers automatically via tools/list. Zero tool definition code needed.
- At $0.005/query, a 20-search agent task costs $0.10. Run 100 tasks per day for $10/day. SerpAPI would cost $20-100/day for the same workload.
- Multi-platform routing lets the agent pick the right search type per sub-task: Google for facts, Reddit for opinions, YouTube for tutorials, Amazon for products.
- Structured JSON responses fit directly into tool call results without post-processing. The agent gets clean titles, URLs, and snippets in a consistent format.
- 500 free credits per month cover agent development and testing. Build, iterate, and test your agent's search behavior before committing to production volume.
