Assets

Fetch tradeable assets, prices, OHLCV candles, and orderbooks

Fetch asset details, prices, OHLCV chart data, and orderbook snapshots.

The examples on this page use Hyperliquid (provider: 'hyperliquid'). Replace the provider value with any supported DEX from getProviders().

getAssets

Returns the token/asset registry for a specified DEX — the base entities referenced by markets (as base/quote legs) and by account balances. Static market metadata (leverage, margin) lives on Market via getMarkets; live data (mark price, funding) lives on MarketContext via getMarketsContext.

import { getAssets } from '@lifi/perps-sdk';

const { assets } = await getAssets(client, { provider: 'hyperliquid' });

for (const asset of assets) {
  console.log(asset.id, asset.displaySymbol);
}
// BTC BTC
// ETH ETH

Parameters

Parameter	Type	Required	Description
client	PerpsSDKClient	Yes	SDK client
params.provider	string	Yes	Provider identifier
options	SDKRequestOptions	No	Request options

Returns

AssetsResponse — { assets: Asset[] }:

Each Asset:

Field	Type	Description
providerId	string	Provider that minted this asset
id	string	Provider’s own asset id. Lighter: numeric asset_id stringified. Hyperliquid spot: the venue token index, never the coin symbol (that lives in displaySymbol).
displaySymbol	string	UI-friendly base symbol (e.g., "BTC", "PURR")
logoURI	string	URL to asset logo
displayName	string?	Full asset name (e.g., "Bitcoin")
tags	string[]?	Curated lowercase-kebab slugs used for search and grouping
aliases	string[]?	Display symbols used by other venues for the same real-world asset
decimals	number?	Venue wire precision for this asset
l1Decimals	number?	L1 token-contract precision, which can differ from venue precision
l1Address	string?	L1 token address; the zero address denotes native gas
minWithdrawalAmount	string?	Venue minimum for one withdrawal, denominated in this asset rather than USD

API Reference: GET /assets

getMarkets

Returns all tradeable markets for a specified DEX as static instrument metadata — ids, base/quote assets, decimals, leverage, and margin. Live data (mark price, funding, open interest, volume) comes from getMarketsContext.

import { getMarkets } from '@lifi/perps-sdk';

const { markets } = await getMarkets(client, { provider: 'hyperliquid' });

for (const market of markets) {
  console.log(market.baseAsset.displaySymbol, market.maxLeverage);
}
// BTC 50
// ETH 50

Parameters

Parameter	Type	Required	Description
client	PerpsSDKClient	Yes	SDK client
params.provider	string	Yes	Provider identifier
params.marketIds	string[]	No	Filter to specific markets by the canonical Market.id (not display symbols)
options	SDKRequestOptions	No	Request options

Returns

MarketsResponse — { markets: Market[] }. A Market is either a PerpsMarket or a SpotMarket; both extend BaseMarket:

Field	Type	Description
providerId	string	Provider that owns this market
id	string	Provider’s canonical, stringified market id that uniquely identifies the trading instrument; referenced elsewhere as marketId
categoryId	string	References a ProviderCategory by id
baseAsset	Asset	Base leg
quoteAsset	Asset	Quote leg
szDecimals	number	Size decimal places
priceDecimals	number?	Price decimal places, when the provider publishes them
isDelisted	boolean?	Whether the venue has delisted the market. Treat only true as delisted.
priceIncrement	string?	Exact price tick as a decimal string when priceDecimals alone cannot describe the venue grid
sizeIncrement	string?	Exact size lot as a decimal string when szDecimals alone cannot describe the venue grid

PerpsMarket adds:

Field	Type	Description
maxLeverage	number	Maximum allowed leverage
onlyIsolated	boolean	Whether only isolated margin is supported
maintenanceMarginRate	number?	Maintenance margin requirement as a fraction (e.g. 0.012 = 1.2%), when the provider publishes it
positionMarginAdjustment	PositionMarginAdjustment	Per-market capability: NONE, ADD_ONLY, or ADD_AND_REMOVE

Live per-market data (mark price, previous-day price, 24h volume, open interest, funding) comes from getMarketsContext.

API Reference: GET /markets

getMarket

Returns a single market by its canonical marketId.

import { getMarket } from '@lifi/perps-sdk';

const btc = await getMarket(client, { provider: 'hyperliquid', marketId: 'BTC' });
console.log(btc.baseAsset.displaySymbol, btc.maxLeverage);
// BTC 50

Parameters

Parameter	Type	Required	Description
client	PerpsSDKClient	Yes	SDK client
params.provider	string	Yes	Provider identifier
params.marketId	string	Yes	The canonical Market.id (not the display symbol)
options	SDKRequestOptions	No	Request options

Returns

Market — single market object (same shape as above).

API Reference: GET /markets

---

getMarketsContext

Returns live per-market context for all markets: midPrice, markPrice, and (where the venue publishes it) oraclePrice; prevDayPrice, priceChange24h, and volume24h for every market; marketCap where the venue publishes circulating supply; and openInterest and funding for perps. Intended for frequent polling; pair it with the static metadata from getMarkets.

import { getMarketsContext } from '@lifi/perps-sdk';

const { prices } = await getMarketsContext(client, { provider: 'hyperliquid' });
for (const p of prices) {
  console.log(p.marketId, p.midPrice, p.markPrice);
}
// 0 95000.50 95000.50
// 1 3200.25 3200.25

PricesResponse — { prices: MarketContext[] }:

Each MarketContext:

Field	Type	Description
marketId	string	The canonical Market.id
midPrice	string	Current mid price
markPrice	string	Current mark price
oraclePrice	string?	Venue oracle/index price, where the venue publishes one
prevDayPrice	string?	Previous day’s price

getMeta

Get platform metadata: the backend version and the list of active platform-level notices. Provider-independent — reads the platform meta surface, so it takes no provider.
