Exa Research

Neural web search via BlockRun. Understands meaning, not keywords. Four distinct actions for different research modes.

How to Call from MCP

As of v0.14.1 the blockrun_exa tool is path-based. Pass the endpoint name as path and the request as body:

blockrun_exa({ path: "search",       body: { query: "AI agent frameworks 2026", numResults: 10 } })
blockrun_exa({ path: "answer",       body: { query: "What is speculative decoding?" } })
blockrun_exa({ path: "contents",     body: { urls: ["https://example.com/a", "https://example.com/b"] } })
blockrun_exa({ path: "find-similar", body: { url: "https://arxiv.org/abs/2401.12345", numResults: 5 } })

Costs below are what you are actually CHARGED — the $0.001 transaction fee is already included (it applies once per call, not per result).
