The value belongs to the underlying rather than the venue, so every market sharing a `unifiedSymbol` reports the same category. example: stocks-us data: description: Custom metadata for specific market exchange: type: string enum: - aster - binance - bybit - extended - gate - hyperliquid - lighter - mexc - ondo - robinhood description: Perpetual exchange fundingInterval: type: integer exclusiveMinimum: 0 maximum: 9007199254740991 description: Funding settlement interval in hours example: 1 fundingRate: type: string description: Hourly funding rate for the market as a decimal. example: '0.001' id: type: string maxLeverage: type: number exclusiveMinimum: 0 description: Highest leverage this market allows, for any account. example: 50 nextFundingTime: description: Next funding settlement time example: '2025-01-15T12:00:00.000Z' type: string format: date-time pattern: >- ^(?:(?:\d\d[2468][048]|\d\d[13579][26]|\d\d0[48]|[02468][048]00|[13579][26]00)-02-29|\d{4}-(?:(?:0[13578]|1[02])-(?:0[1-9]|[12]\d|3[01])|(?:0[469]|11)-(?:0[1-9]|[12]\d|30)|(?:02)-(?:0[1-9]|1\d|2[0-8])))T(?:(?:[01]\d|2[0-3]):[0-5]\d:[0-5]\d(?:\.\d+)?(?:Z))$ open: type: boolean example: true openInterest: type: string description: >- Open interest as USD notional, one-sided.
