Qfex

QFEX is the first 24/7 exchange built exclusively for US equities, commodities, and FX, offering high-leverage perpetual futures on traditional assets without a broker. Founded by former Tower Research and Citadel engineers who met studying mathematics at Cambridge, QFEX gives retail and institutional traders direct, high-frequency access to markets around the clock. Its developer platform exposes a REST API for historic market data and account operations, two multiplexed WebSocket gateways (market data and trading) documented with AsyncAPI 3.0, and a JSON-native CLI purpose-built for agentic trading workflows. Authentication uses HMAC-SHA256 request signing with public/secret API key pairs.

Qfex publishes 5 APIs on the APIs.io network, including Market Data WebSocket (MDS), Trade WebSocket, market-data API, and 2 more. Tagged areas include Company, Trading, Exchange, Perpetual Futures, and Market Data.

The Qfex catalog on APIs.io includes 3 event-driven AsyncAPI specifications.

Qfex’s developer surface includes documentation, API reference, getting-started guide, authentication, CLI, sandbox, changelog, and 23 more developer resources.
