    Hyperliquid Outcomes

    Outcome User Activity

    PREVIEW

    At least one of `user`, `coin`, `outcome_id`, or `question_id` is required — calls without any of these return 400.

    Returns the chronological composition-event feed for HIP-4 outcome positions — one row per (event, affected leg). Covers SETTLEMENT (resolution payouts), SPLIT_OUTCOME (mint Yes+No from collateral), MERGE_OUTCOME (redeem Yes+No to collateral), MERGE_QUESTION (redeem the full Yes-set of a multi-outcome question), and NEGATE_OUTCOME (convert a No-A holding into Yes-on-every-other-outcome under the same question).

    BUY/SELL taker fills are not served by this endpoint — query /v1/hyperliquid/outcomes/trades for those. The direction enum here is restricted to the five composition tags; passing BUY/SELL returns 400.

    Filters compose additively. Defaults to the last 24 hours when no time range is specified.

    closed_pnl carries the realized USDC delta for the row's leg (settlement payouts on the winning leg are positive; merge/redeem rows carry the collateral-side delta). For position-level rollups see /v1/hyperliquid/outcomes/users; for current open share balances see /v1/hyperliquid/outcomes/users/positions.

    Every row embeds the compact outcome leg context (outcome_id, outcome_name, question_id, question_name, status, settle_fraction, coin, side_index, side_label). For full outcome metadata call /v1/hyperliquid/outcomes?outcome_id=....
