# Surf **Canonical:** https://apis.io/providers/surf/ **Website:** https://asksurf.ai/ **APIs profiled:** 1 Surf (asksurf.ai) is a crypto-focused AI research and execution platform that exposes its intelligence as a developer API. The Surf Data API ("Hermod" gateway) provides 119 typed REST endpoints across 14 domains — exchange and market data, tokens, DeFi projects, wallets, on-chain SQL, social signals, news, funds, prediction markets (Polymarket/Kalshi), Hyperliquid perps, search, and web fetch — covering 40+ blockchains and 200+ data sources. A separate OpenAI-style Chat API (surf-2.0 / surf-2.0-instant models) answers natural-language crypto research questions with citations. Access is via a single Bearer API key with credit-based billing (30 free credits/day, no signup), and the platform ships a Go CLI, an MCP server, an Agent Skill, and a TypeScript SDK. Surf is backed by Pantera Capital. ## Kin Score — 39.7 / 100 (developing) Scored 2026-08-30 under rubric 0.17.2.
