Coding agents like Claude Code, Cursor, and OpenCode are more effective when they can search the web for current documentation, API references, and error solutions. The best search API for a coding agent must support MCP or be easy to configure as a tool, return structured results fast enough for interactive use, and have a free tier generous enough for daily development. We tested five options across these criteria.
Scavio wins for coding agents because it offers a ready-to-use MCP server at mcp.scavio.dev/mcp, 250 free credits per month (enough for daily coding sessions), and multi-platform search covering Google docs, Reddit discussions, and YouTube tutorials under one key.

Why Scavio Wins
- MCP server at mcp.scavio.dev/mcp works with Claude Code, Cursor, and any MCP-compatible agent without writing integration code.
- 250 free credits per month covers typical development usage. A coding session rarely exceeds 20-30 searches.
- Multi-platform search means the agent can check Google docs, Reddit threads, and YouTube tutorials without separate API keys.
- Structured JSON responses parse cleanly into tool call results, reducing token overhead in the agent's context window.
- Single API key simplifies environment setup across development machines and CI/CD pipelines.
