REST and WebSocket order entry, post-only and batch quoting, and one cross-margined dollar account. Developers About English [Trade](/trade)[API Reference](https://docs.nexus.xyz/api-reference) English ## One API for perpetual futures The Nexus Exchange lists BTC, ETH and SOL perpetuals on one cross-margined dollar account. Every order is a signed REST or WebSocket call, margin is checked inside the matching engine, and the terminal is one client of the API.

Each order passes through one engine that checks its margin, matches it and settles the fill to a dollar balance. Who calls it - Market makers - Quant and pro traders - Developers building on the Exchange - Agents Nexus API - 01 Order entry Signed REST and WebSocket requests - 02 Pre-trade risk Margin checked before an order is accepted - 03 Matching Central limit order book, price-time priority - 04 Margin and liquidation One cross-margined account across every position - 05 Settlement Fills settle to your dollar balance What it reaches - BTC Perpetual - ETH Perpetual - SOL Perpetual Why Nexus ### Built for trading systems What a desk checks before it connects: the API surface, the order handling and the risk model. [API reference](https://docs.nexus.xyz/api-reference)[Market maker guide](https://docs.nexus.xyz/apis-and-rates/apis-and-rates/market-maker-guide) - 01 #### API first Anything the terminal does is a REST or WebSocket call, and some API capabilities have no screen at all. Public market data needs no key. - 02 #### One dollar account A single dollar balance cross-margins every BTC, ETH and SOL position you hold, under one risk model. - 03 #### Quote, amend, pull Post-only rejects rather than crossing. Refresh a ladder in one batch request, amend price and size in place, and clear a market with one cancel-all. - 04 #### Risk inside the engine Margin is checked inside the matching engine before an order is accepted, not reconciled after the fill. - 05 #### Errors a program can read Every refusal carries a stable, machine-readable code, and an order's client ID means a retry never places it twice. - 06 #### Bring your stack Rust, Python, TypeScript and Go SDKs sign requests for you, there is a CLI over the Rust one, and CCXT-compatible endpoints are live for market data. Who it's for ### For anyone trading by code - #### Market makers Quote both sides with post-only and batch requests, and pull a whole market with one cancel-all. - #### Quant and pro traders Run strategies on the same API the terminal uses, from the language you already work in. - #### Developers building on the Exchange Anything the terminal does is in the API, the SDKs and the CLI, so you build on the same surface it runs on. - #### Agents Connect an agent through the MCP server and agent skills, and point it at llms.txt to read the docs. Developers ### How to connect Start with the API: anything the terminal does is a REST or WebSocket call, and public market data needs no key. The SDKs, the CLI, the MCP server and agent skills are open-source clients of the same API.
