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.

Surf publishes 16 API contracts indexed on the APIs.io network, including DEX API, Exchange API, Fund API, and 13 more. Tagged areas include Company, Cryptocurrency, Blockchain, Market Data, and On-Chain Analytics.

Surf’s developer surface includes engineering blog, documentation, API reference, getting-started guide, pricing, signup flow, authentication, and 17 more developer resources.

Regulatory Posture applies to this provider. Its tags matched the Securities & Market Data regime, so Regulatory Posture carries 15 points of the composite. If this regime is wrong for your business, say so on your provider repo — the applicability map is public and we will correct it.

Create-or-Update Ergonomics could not be measured. We hold no machine-readable contract for this provider to read, so there is nothing to measure a write surface against. Excluded rather than scored zero: never-measured and measured-empty are different facts. Publishing an OpenAPI is what makes this facet — and several others — scorable at all.

The six quality facets above are damped to 85 points between them, because the conditional facet above carries the other 15. That is why each facet's contribution is shown against a damped maximum: raising a quality facet moves the composite by 85% of its nominal weight, not 100%. The full arithmetic is at apis.io/rating/.

Agent readiness — checks not met, largest first (exact, from this profile):

Agentic Access Contract +10 pts — agentic_access artifact present (x-agentic-access), graded by author
Idempotency +9 pts — OpenAPI mutating operations declare an idempotency key — a header, a request-body property, or a named de-duplication token whose own description says so (verified); else common[].type matches /idempoten/i (documented)
A2A Agent Card +8 pts — a2a/-a2a.yml manifest, graded on conformance.grade against A2A 1.0.0
Rate-Limit Signaling +7 pts — OpenAPI responses document X-RateLimit-* / RateLimit headers (verified), else a rate_limits artifact or RateLimits link (documented)
Request/Response Examples +7 pts — share of operations carrying request/response examples; else an Examples / Code Samples link
Delegated User Identity +6 pts — a served discovery document listing authorization_code in grant_types_supported (served), else an oauth2 authorizationCode flow or openIdConnect declared in an OpenAPI (documented)

Markets this provider is in provisional

The Kin Score Market layer reads a provider inside its market: its position, and how deep its integrations go. Depth is only comparable within a position. Provisional and unweighted: not part of the Kin Score or agent readiness.

Registered MCP server and declares compatibility are report only — not weighted. Undeclared means we found nothing we can read, so there is no number: we never infer integrations.
