Hashflow
Hashflow is a decentralized exchange (DEX) and the leading request-for-quote (RFQ) trading platform in crypto. Instead of an automated market maker (AMM) pricing curve, Hashflow brokers signed, off-chain-priced quotes from a network of professional market makers, giving traders zero-slippage, MEV-protected swaps across EVM chains and Solana, including cross-chain trades. Market makers publish price levels and respond to RFQs with EIP-712 signed quotes that settle on-chain via the HashflowRouter contract. Developers integrate through the Taker API v3 (market-makers, price-levels, rfq, and restrictions endpoints) and market-maker tooling, with first-party JavaScript and Python SDKs.
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 Hashflow the way a machine reads it — 6 machine-readable artifacts across 2 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 — Hashflow scores 33.7/100 (thin), with a separate agent-readiness read of 34/100 (agent aware). 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 Hashflow
Each block below is one kind of artifact we hold for Hashflow. 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 2
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.
Individual APIs this provider publishes, each with its own machine-readable definition.
Hashflow Taker API v3
REST API for takers/aggregators: discover market makers, query indicative price levels, request signed executable RFQ quotes, and check trader rate-limit restrictions. Quotes se...
Hashflow Market Maker API v3
REST API for market makers: publish price levels, receive RFQs, sign quotes, and manage restrictions on the Hashflow exchange.
MCP Servers 1
Model Context Protocol servers expose these APIs directly to AI agents. We profile them because agent-native access is the fastest-growing way this provider's capabilities actually get used.

MCP SERVERSecurity Posture 3
Authentication, domain security, vulnerability disclosure, and trust-center signals — the evidence that a provider takes security seriously enough to document it. We profile it because you can't govern what you can't see.
