Surf gives AI coding agents and developers direct access to crypto intelligence — market data, wallets, social, on-chain analytics, prediction markets, and more. There are two ways to use it:
  • Surf Skill — Install into your AI agent (Claude Code, Codex, etc.) so it automatically knows how to fetch crypto data when you ask. This is the recommended way for most users.
  • Surf CLI — A standalone command-line tool for terminal-based research, scripting, and automation.

​
Quick Start

Once installed, just ask your agent things like “what’s the price of ETH” or “show me the top wallets holding AAVE” — the skill handles the rest.

With the CLI Directly

No API key needed — you get 30 free credits per day. For unlimited access, run surf auth to save your key.
