Instruments Metadata API
API providing useful instrument metadata (tick sizes, contract multipliers, normalised base and quote currencies, expiration dates etc.)
Please provide 'Authorization' header with value: 'Bearer YOUR_API_KEY'.
Returns instrument info for provided exchange and symbol.
changes info returned by the API is meant to be accurate and complete only for contractMultiplier values (we monitor exchanges announcements for that), rest of the changes are done on best effort basis and not always complete.{
id: string // symbol id
datasetId: string // id used for CSV datasets downloads
exchange: string // exchange id
baseCurrency: string // normalized, so for example bitmex XBTUSD has base currency set to BTC not XBT
quoteCurrency: string // normalized, so for example bitfinex BTCUST has quote currency set to USDT, not UST
type: 'spot' | 'perpetual' | 'future' | 'option'
active: boolean // indicates if the instrument can currently be traded.
availableSince: string, // date in ISO format
availableTo: string | undefined, // date in ISO format
expiry: string | undefined // in ISO format, only for futures and options
priceIncrement: number // price tick size, price precision can be calculated from it
amountIncrement: number // amount tick size, amount/size precision can be calculated from it
minTradeAmount: number // min order size
margin: boolean | undefined // set to true for margin enabled spot currency pairs, only available for spot symbols
makerFee: number // consider it as illustrative only, as it depends in practice on account traded volume levels, different categories, VIP levels, owning exchange currency etc
takerFee: number // consider it as illustrative only, as it depends in practice on account traded volume levels, different categories, VIP levels, owning exchange currency etc
inverse: boolean | undefined // only for derivatives
contractType: "move" | "linear_future" | "inverse_future" | "quanto_future" | "linear_perpetual" | "inverse_perpetual" | "quanto_perpetual" | "put_option" | "call_option" | "turbo_put_option" | "turbo_call_option" | "spread" | "interest_rate_swap" | "repo" | "index" // only for derivatives, detailed contract type
contractMultiplier: number | undefined // only for derivatives
quanto: boolean | undefined // set to true for quanto instruments, otherwise undefined
settlementCurrency: string | undefined // settlement currency, only for quanto instruments as it's different base/quote currency
strikePrice: number | undefined // strike price, only for options
optionType: 'call' | 'put' // option type, only for options
changes: undefined | {
until: string // date in ISO format
