Infoway Real-time Market Data API
Infoway is a real-time and historical financial market-data provider covering equities (US, Hong Kong, China A-shares, Japan, South Korea, India), forex, cryptocurrencies across 30+ exchanges, and commodities/futures. It ships two surfaces from the host data.infoway.io: a REST/HTTP API for symbol reference data, trading calendars, last-trade ticks, order-book depth and candlestick (K-line) history, and a WebSocket streaming API that pushes trades, depth, candles and multilingual news with millisecond latency. Both authenticate with a single API key whose entitlements follow the plan it was issued against (Free through Professional). Infoway publishes per-endpoint OpenAPI 3.0.0 definitions on its ReadMe developer hub, official Python, Node.js and Java SDKs, an llms.txt documentation index, and a stdio MCP server exposing 17 financial-data tools with a provider-authored Agent Skill.
Real signal across most facets with visible, nameable gaps — the contract exists but is thin, or the portal is good while governance and commercial terms are absent.
API Evangelist profiles Infoway Real-time Market Data API the way a machine reads it — 14 machine-readable artifacts across 5 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 — Infoway Real-time Market Data API scores 47.5/100 (developing), with a separate agent-readiness read of 44/100 (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 Infoway Real-time Market Data API
Each block below is one kind of artifact we hold for Infoway Real-time Market Data API. 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 5
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.

Persistent WebSocket connection for real-time trades, order-book depth, candlesticks and multilingual news. Integer protocol-code framing (10000 subscribe trade, 10002 trade pus...

Open Collections 4
Open, tool-agnostic collections carry the same runnable value as Postman without locking you to one client — the portable, forkable form of the same exercise.

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.

Rate Limits 1
Rate limits are the difference between a demo that works and a production integration that doesn't fall over. Publishing them is an operational-transparency signal — and a hard requirement for any agent that plans its own throughput.
Documented rate limits and quota policies.
Event Specifications 1
Not every API is request/response. AsyncAPI describes the event-driven and streaming side — the webhooks and channels — so the asynchronous half of the interface is documented the same way the synchronous half is.
AsyncAPI definitions for this provider's event-driven and streaming APIs.
Infoway WebSocket Streaming API
Real-time push of trades, order-book depth, candlesticks (K-line) and news over a single WebSocket connection. PROVENANCE: Infoway publishes NO AsyncAPI document. This document ...
ASYNCAPISecurity Posture 2
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.

This is an independent, third-party profile of Infoway Real-time Market Data API, published by API Evangelist. We do not operate, host, resell, or support these APIs, and we are not affiliated with or endorsed by the company unless stated above. Everything here is built from publicly available information — the company's own site, developer portal, documentation, public repositories, and the specifications it publishes for public use. Nothing is obtained by breaching a system, defeating an access control, or using credentials.
The Kin Score and Agent Readiness rating are independently calculated assessments of a company's public API artifacts, scored against a published rubric. They are not certifications, endorsements, security assessments, or audits.
Corrections, re-scores, and removal are free — no partnership or purchase required, and you do not need to justify the request. A removed company is recorded as unrated, never scored zero for having asked. Acknowledgement within one business day; removal within two.
