Web Search API (Exa wrapper)

free 5/IP/day · paid ~$0.02 / call (x402)

POST a query → ranked web results with snippets via Exa (no LLM synthesis). Cheaper/faster than S2 research. MCP tool: search_web.

Buyer: Agents that need live links/snippets without a full research brief

Fake-door for now: clicking subscribe records intent only. x402 settlement ships after demand clears the bar.
