Overview
Surf — AI-powered market intelligence for agents and developers
What is Surf?
Surf is a unified market intelligence platform for AI agents. Install the Surf Skill for crypto workflows, or use the Data API and MCP server for crypto and US equity data — market data, on-chain analytics, prediction markets, company financials, valuation metrics, and ETF holdings under one API key. For natural language queries, the Chat API provides an OpenAI-compatible Responses endpoint powered by the surf-2.0 model family, so you can ask anything about markets and get AI-synthesized answers with citations.
