Getting Started

Use SDK v2 when you want HTTP-backed GMX data or API-relayed order workflows without wiring RPC, oracle, or Subsquid connections yourself.

Install the shared SDK package first:

npm install @gmx-io/sdk

Then import the client from the v2 subpath:

import { GmxApiSdk } from "@gmx-io/sdk/v2";

const apiSdk = new GmxApiSdk({ chainId: 42161 }); // Arbitrum

const markets = await apiSdk.fetchMarkets();
const marketsInfo = await apiSdk.fetchMarketsInfo();
const tickers = await apiSdk.fetchMarketsTickers({
  symbols: ["BTC/USD"],
});
const tokens = await apiSdk.fetchTokens();
const tokensData = await apiSdk.fetchTokensData();
const pairs = await apiSdk.fetchPairs();
const rates = await apiSdk.fetchRates({ period: "7d" });
const apy = await apiSdk.fetchApy({ period: "7d" });
const annualized = await apiSdk.fetchPerformanceAnnualized({
  period: "30d",
});
const snapshots = await apiSdk.fetchPerformanceSnapshots({
  period: "30d",
});
const positions = await apiSdk.fetchPositionsInfo({
  address: "0x9f7198eb1b9Ccc0Eb7A07eD228d8FbC12963ea33",
  includeRelatedOrders: true,
});
const orders = await apiSdk.fetchOrders({
  address: "0x9f7198eb1b9Ccc0Eb7A07eD228d8FbC12963ea33",
});
const candles = await apiSdk.fetchOhlcv({
  symbol: "BTC/USD",
  timeframe: "1h",
  limit: 100,
});

GmxApiSdk calls the GMX API directly — no RPC endpoint, oracle URL, or Subsquid URL required. It supports Arbitrum, Avalanche, Botanix, and MegaETH on mainnet, plus Arbitrum Sepolia for testing. The constructor throws for unsupported chains.

If your app switches chains dynamically, prefer isApiSupported(chainId), getApiUrl(chainId), and getApiFallbackUrls(chainId) from @gmx-io/sdk/configs/api instead of hardcoding API hosts.

GMX API deployment

Mainnet chains are each served by two independent peer base URLs — https://{chain}.gmxapi.io/v1 and https://{chain}.gmxapi.ai/v1. Both receive the same data and accept the same requests. By default, GmxApiSdk builds an HttpClientWithFallback from getApiUrl(chainId) and getApiFallbackUrls(chainId), starts from a randomized peer, and tries the other peer for server or network errors.

Arbitrum Sepolia uses a separate test host returned by getApiUrl(421614). Test hosts can change between alpha releases, so use the exported helper instead of hardcoding the URL.

@gmx-io/sdk/v2 is an import path inside the @gmx-io/sdk package, not a separate npm package.

If you're using CommonJS, require the v2 client from the v2 subpath:

const { GmxApiSdk } = require("@gmx-io/sdk/v2");

const apiSdk = new GmxApiSdk({ chainId: 42161 });

TypeScript subpath resolution is supported for @gmx-io/sdk/v2 and the SDK's utility, config, ABI, and type-only entrypoints.

What SDK v2 covers today

Workflow	Status	Notes
Read market catalogs, tickers, and token data over HTTP	✅	Available through fetchMarkets(), fetchMarketsInfo(), fetchMarketsTickers(), fetchTokens(), and fetchTokensData()
Read pairs, rates, APY, and performance analytics over HTTP	✅	Available through fetchPairs(), fetchRates(), fetchApy(), fetchPerformanceAnnualized(), and fetchPerformanceSnapshots()
Read one account's positions and orders over HTTP	✅	Available through fetchPositionsInfo() and fetchOrders()
Read OHLCV candles over HTTP	✅	Available through fetchOhlcv()
Read protocol buyback stats over HTTP	✅	Available through fetchBuybackWeeklyStats()
Read staking power over HTTP	✅	Available through fetchStakingPower()
Read wallet balances and allowances over HTTP	✅	Available through fetchWalletBalances() and fetchAllowances()
Build approval transaction calldata	✅	Available through buildApproveTransaction()
Submit, edit, cancel, or track orders	✅	Signed order intents are posted to the GMX API, which relays express orders via Gelato. SDK v1 and direct contracts remain available for integrations that prefer RPC.
One-click-trading subaccount helpers	✅	Available through generateSubaccount(), activateSubaccount(), clearSubaccount(), fetchSubaccountStatus(), prepareSubaccountApproval(), and signSubaccountApproval()
Trade history reads	❌	Use SDK v1 or GraphQL

See Order Examples for runnable code showing how to open, close, edit, cancel, and track orders, including TP/SL, TWAP, classic mode, and one-click trading flows.

Methods

GmxApiSdk exposes the following methods. All of them call the GMX API directly -- no RPC, oracle, or Subsquid connection is required.

Method	Parameters	Returns	Notes
fetchMarkets()	--	MarketWithTiers[]	Market catalog data from /markets
fetchMarketsInfo()	--	RawMarketInfo[]	Market definitions and pricing from /markets/info
fetchMarketsTickers(params?)	addresses?: string[], symbols?: string[]	MarketTicker[]	Filterable market tickers from /markets/tickers
fetchTokens()	--	Token[]	Static token catalog from /tokens
fetchTokensData()	--	TokenData[]	Token metadata and current prices from /tokens/info
fetchPairs()	--	Pair[]	Pair-level summary data from /pairs
fetchRates(params?)	period?: ApiParameterPeriod, `averageBy?: "1d"	"7d"	"30d", address?: string`
fetchApy(params?)	period?: ApiParameterPeriod	ApyResponse	Market and GLV APY data from /apy
fetchPerformanceAnnualized(params?)	period?: ApiParameterPeriod, address?: string	PerformanceAnnualized[]	Annualized performance summaries from /performance/annualized

fetchPositionsInfo(params)	address: string, includeRelatedOrders?: boolean	ApiPositionInfo[]	Position objects for an address; optionally includes related orders
fetchOrders(params)	address: string	ApiOrderInfo[]	Active order objects for an address
fetchOhlcv(params)	symbol: string, timeframe: string, limit?: number, since?: number	OhlcvCandle[]	OHLCV candle data from /prices/ohlcv
fetchBuybackWeeklyStats()	--	BuybackWeeklyStatsResponse	Weekly buyback accrual data and cumulative summary from /buyback/weekly-stats
fetchStakingPower(params)	address: string	StakingPowerResponse	Staking power, loyalty ratio, and reward share data for an address from /staking/power

Account and order methods

These methods cover wallet data, approval calldata, API-relayed order workflows, and one-click-trading subaccounts.

• fetchWalletBalances({ address }) returns wallet balances from /balances/wallet.
• fetchAllowances({ address, spender }) returns token allowances from /allowances. spender is "router" or "glv".
• buildApproveTransaction(params) builds ERC-20 approval calldata for the selected chain.
• prepareOrder(request) prepares a swap, increase, or decrease order and returns either typed data for express mode or transaction calldata for classic mode. See Order Examples for full usage.
• signOrder(prepared, signer) signs a prepared express order with an IAbstractSigner.
• submitOrder(request) submits a signed express order intent to /orders/txns/submit.
• executeExpressOrder(request, signer) runs the common prepare, sign, and submit flow in one call.
• fetchOrderStatus({ requestId }) returns relay, creation, execution, cancellation, and error state for an API-relayed order request.
• prepareEditOrder(request), prepareCancelOrder(request), and prepareCollateral(request) prepare edit, cancel, collateral deposit, or collateral withdrawal order intents.
• fetchSubaccountStatus(request), prepareSubaccountApproval(request), and signSubaccountApproval(prepared, signer) support one-click-trading authorization flows.
• generateSubaccount(mainSigner), activateSubaccount(mainSigner, options?), and clearSubaccount() manage the SDK's local subaccount state. When an active subaccount exists, executeExpressOrder() signs with the subaccount automatically.

PrivateKeySigner and the IAbstractSigner type are exported from @gmx-io/sdk/v2. Lower-level signer helpers are also available from @gmx-io/sdk/utils/signer.

Staking power timestamps

StakingPowerResponse includes two protocol-level timestamps that are constant across all addresses:

Field	Type	Description
powerAccrualStart	unix seconds	The moment power began accumulating for staked GMX. Set to 1772582400 (March 4, 2026 00:00:00 UTC).
loyaltyTrackingStart	unix seconds	The moment loyalty tracking became active. Before this time, unstaking did not affect the historical peak used for loyalty enforcement. Set to 1774396800 (March 25, 2026 00:00:00 UTC).

After loyaltyTrackingStart, if an account's staked balance drops below 80% of its historical peak, accumulated power resets to zero. See Rewards for the user-facing description of how the loyalty threshold works.

When to use SDK v2

Use GmxApiSdk for API integrations that need market, ticker, token, pair, rate, APY, performance, position, order, OHLCV, wallet-balance, allowance, buyback, or staking-power data, or API-relayed order submission, edit, cancellation, and subaccount flows. Use the full GmxSdk (SDK v1) when you need trade history or direct RPC-backed transaction ownership.

note

GmxApiSdk is under active development and covers an expanding share of the full SDK surface, replacing the need for direct RPC, oracle, and Subsquid connections. Order submission runs via the GMX API's Gelato relay. The GMX API OpenAPI Reference documents the underlying HTTP endpoints, while this page documents the typed SDK method names and signing helpers.
