Surf
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.
Limited machine-readable signal and partial portal coverage — documentation a human can read, but little a machine or agent can consume without scraping.
API Evangelist profiles Surf the way a machine reads it — 19 machine-readable artifacts across 16 APIs, pulled from the provider's own public surface and indexed so a developer, an analyst, or an AI agent can evaluate it against every other provider on the network.
Every provider in the network is reduced to the same set of machine-readable artifacts — OpenAPI contracts, event specifications, GraphQL schemas, runnable collections, pricing and rate-limit signals, security posture, OAuth scopes, and the agent surfaces (MCP servers and skills) that let software drive the API on its own. We profile them because the interface is the part of a company you can actually inspect: it is a truer signal of what a provider does than any marketing page. From those artifacts we compute the Kin Score — Surf scores 43.3/100 (thin), with a separate agent-readiness read of 51/100 (agent ready). The full breakdown is below, followed by every artifact we hold — each card links through to its machine-readable definition on apis.io.
Kin Score
This is the API Evangelist rating — a single, repeatable read computed from the artifacts on this page. Green fill is points earned; the red track is points possible, so every bar shows earned-versus-possible at a glance.

How we profile Surf
Each block below is one kind of artifact we hold for Surf. For each we say what it is and why it earns a place in the profile, then list every one we've indexed — capped at two rows, scroll within the panel for the rest.
APIs 16
Each API is captured as its own OpenAPI definition — every operation, parameter, and response. This is the single most useful machine-readable description of what an API does, and it's what lets us score, lint, mock, and generate against it without asking the provider for anything.
