# Surf — Crypto Data via BlockRun Surf (asksurf.ai) aggregates **84 crypto data endpoints** across CEX market data, on-chain SQL (13 chains, 80+ ClickHouse tables), 100M+ labeled wallets, prediction markets (Polymarket + Kalshi side-by-side), social/CT intelligence, news, unified search, and Surf-1.5 chat with citations.
