Question

Field	Meaning
`questionId`	Hyperliquid question ID, e.g., `820`
`name`	Question name, e.g., `"May CPI year-over-year"`
`description`	Resolution description
`fallbackOutcome`	Fallback outcome ID, e.g., `10217`
`namedOutcomes`	Outcome IDs belonging to the question, e.g., `[10218]`
`settledNamedOutcomes`	Named outcomes that have settled
`outcomes`	Outcome definitions

Outcome

Field	Meaning
`outcomeId`	Hyperliquid outcome ID, e.g., `10218`
`name`	Outcome name, e.g., `"Below 4.3%"`
`description`	Resolution description
`quoteToken`	Quote token, e.g., `"USDC"`
`sides`	Tradable outcome sides

Side

Field	Meaning
`sideIndex`	Zero-based side index, e.g., `0`
`label`	Human-readable label, e.g., `"Yes"`
`assetId`	16-character AssetId, e.g., `"0004000005f77024"`
`hlEncoding`	Encoded outcome-side ID, e.g., `100102180`
`settleFraction`	Final fraction, e.g., `"1"`, or `null` before settlement

Use the side’s assetId in the standard Notional order action. Do not send hlEncoding as the order AssetId. Use the outcome’s numeric outcomeId with userOutcome.mergeOutcome to merge an equal number of its Yes and No shares back into USDC. Do not use a side assetId or hlEncoding as the merge outcome ID. Only outcomes currently available for trading are returned. An empty array is valid, including when the connected Hyperliquid market does not provide outcome products.
