GET /api/v1/account/state

Consolidated account state

Consolidated account state.

operationId: fetchAccountStateV1

Declared server differs from the callable one. This path declares its own servers base of https://exchange.nexus.xyz, without the /api/exchange mount the document default carries. Measured 2026-09-02, the override is not routed — https://exchange.nexus.xyz/api/v1/account/state returns 404 while the gateway form in the sample below is routed. A client generated from this contract will aim at the override; pin the gateway base until the per-network hosts are live. See Networks.

Not reachable through CCXT. Nexus account aggregates. fetchBalance is the CCXT-shaped view; these are richer and unmapped by design.

Authentication: hmacAuth.

Full account state in a single call: the portfolio summary aggregates plus all open positions ({ summary, positions }). Saves clients from pairing /account/summary with /positions, matching Hyperliquid clearinghouseState ergonomics. Both parts are built from one coherent read, so summary.open_positions_count always matches the positions length, and the embedded summary is identical to the standalone /account/summary response. Fails closed with 502 when the engine-authoritative margin view is unavailable.

Example

cURL

curl -X GET 'https://exchange.nexus.xyz/api/exchange/api/v1/account/state' \
  -H 'X-API-Key: nx_7f3a1b...' \
  -H 'X-Timestamp: 1776033911836' \
  -H 'X-Signature: <hmac-sha256>'

Python

import requests

headers = {
    "X-API-Key": "nx_7f3a1b...",
    "X-Timestamp": "1776033911836",
    "X-Signature": "<hmac-sha256>"
}

response = requests.get("https://exchange.nexus.xyz/api/exchange/api/v1/account/state", headers=headers)
response.raise_for_status()
print(response.json())

TypeScript

const response = await fetch("https://exchange.nexus.xyz/api/exchange/api/v1/account/state", {
  method: "GET",
  headers: {
    "X-API-Key": "nx_7f3a1b...",
    "X-Timestamp": "1776033911836",
    "X-Signature": "<hmac-sha256>"
  },
});
if (!response.ok) throw new Error(`${response.status} ${await response.text()}`);
console.log(await response.json());

X-Signature is a placeholder: it is derived from this specific request. See Authentication for the canonical string and the HMAC rule.
