Questions, answered.

What is DataMaxi+?

DataMaxi+ is a real-time data terminal and API for crypto arbitrage. It tracks cross-exchange price spreads, funding-rate gaps, spot-perp basis, and new-listing events across 20+ global and Korean exchanges, and delivers them over web, REST, WebSocket, Telegram, and an MCP server for AI agents.

What arbitrage data does DataMaxi+ provide?

Cross-exchange spot spreads (including kimchi premium), funding-rate arbitrage with a ranked funding-gap scanner, spot-perp basis and cross-exchange perpetual spreads, and event-based new-listing arbitrage. Derivatives context — a funding matrix, open interest, and live liquidations — sits alongside to size and time each trade.

Which exchanges does DataMaxi+ cover?

20+ venues, including global CEXs (Binance, Bybit, OKX, MEXC, Bitget, Gate, HTX, HashKey), the Korean exchanges Upbit and Bithumb, and major perpetual DEXs. Coverage varies per metric — the API exposes the exact venue list for each endpoint.

What new-listing alerts does DataMaxi+ provide?

New CEX listing announcements the moment they land, with Korean-won (KRW) listings on Upbit and Bithumb as the flagship, plus delisting and caution schedules. Alerts stream over Telegram, WebSocket, and the web terminal, and feed the listing-arbitrage scanner end to end.

How do I get DataMaxi+ arbitrage data via API?

Over a REST API and WebSocket, with SDKs for Python, TypeScript, and Rust. AI agents can connect through the DataMaxi+ MCP server, and traders can use the web terminal and Telegram channels. Every channel serves the same data — authenticate REST and WebSocket with the X-DTMX-APIKEY header.

Does DataMaxi+ cover stocks or other markets?

Today DataMaxi+ focuses on crypto arbitrage. Coverage of other markets such as equities, FX, and macro data is on the roadmap — the same terminal, extended to any market you need to size a position.
