Search Router

io.github.ainode-tech/search-router

This is a tiered web search API that charges in USDC on the Base blockchain. You get four search depth options: simple, medium, deep, and cached results, all priced at 402 USDC per transaction. There's also a free health check endpoint. Reach for this when you need programmatic web search with different quality levels and you're comfortable paying per query in stablecoins. The pricing model is unusual for an MCP server, trading the typical API key approach for crypto micropayments. If you're building agents that need occasional deep web research and you've got a Base wallet set up, it slots right in via streamable HTTP transport.
