HIP-4 (Outcome Markets) introduces fully collateralized outcome contracts on HyperCore. Two market types are supported: binary (class:priceBinary) markets that settle Yes or No based on a single target price, and multi-price (class:priceBucket) question markets that group multiple binary sub-outcomes into price buckets so that exactly one settles to Yes. Each outcome defines two sides (Yes/No) that trade as #N-prefixed assets and settle within a fixed price range at expiry. This endpoint returns active outcome metadata including side names, encoded description strings, and (for question markets) the full question structure with named bucket outcomes and a fallback outcome.

Parameters

type

string

REQUIRED

Request type identifier. Must be 'outcomeMeta'

Returns

outcomes

array

Array of active outcome markets

outcome

integer

Zero-based index of this outcome. Used to derive asset IDs: side 0 of outcome N has coin '#(N10+0)', side 1 has '#(N10+1)', etc. The encoding formula is: encoding = (outcomeIndex * 10) + sideIndex.

name

string

Human-readable market name (e.g., 'Recurring')

description

string

Encodes the outcome type. One of: (1) Pipe-delimited binary spec: 'class:priceBinary|underlying:ASSET|expiry:YYYYMMDD-HHMM|targetPrice:N|period:Nd': expiry in UTC; (2) 'other': fallback outcome for a multi-price question (settles Yes if no named outcome settles Yes); (3) 'index:N': the Nth named price-bucket outcome within a question (zero-indexed).

sideSpecs

array

Array of side metadata objects, one per outcome side (e.g., Yes and No for binary outcomes)

name

string

Label for this side (e.g., 'Yes' or 'No')

questions

array

Array of multi-price question markets. Each question groups multiple binary sub-outcomes (named price buckets plus a fallback) so that exactly one settles to Yes.

question

integer

Zero-based index of this question.

name

string

Human-readable question name (e.g., 'Recurring').

description

string

Pipe-delimited spec string: 'class:priceBucket|underlying:ASSET|expiry:YYYYMMDD-HHMM|priceThresholds:P1,P2|period:Nd'. priceThresholds is a comma-separated list of price levels that define the bucket boundaries (e.g., two thresholds create three buckets). Expiry is in UTC.

fallbackOutcome

integer

Index (into the top-level outcomes array) of the fallback outcome, which has description 'other' and settles Yes if no named bucket outcome settles Yes.

namedOutcomes

array

Ordered list of outcome indices (into the top-level outcomes array) for each price bucket, from lowest to highest. Each entry has description 'index:N' where N is its position in this list.

settledNamedOutcomes

array

Subset of namedOutcomes indices that have already settled. Empty while the question is open.
