The Hyperliquid info endpoint with type: "outcomeMeta" is used to enumerate all active HIP-4 binary outcome markets on HyperCore.
Estimate your monthly cost for this API using the Pricing Calculator.
  • Wire-equal to POST api.hyperliquid.xyz/info with {"type": "outcomeMeta"}.
  • For real-time price updates on a discovered outcome, subscribe to ohlcvCandlesForPair using the per-side encoding. See the HIP-4 markets recipe for end-to-end discovery and streaming patterns.
  • HIP-4 launched on Hyperliquid mainnet on May 2, 2026. Read the canonical spec: HIP-4: Outcome markets.
Returns the live HIP-4 outcome universe: every active binary outcome market on HyperCore with its integer outcome ID, human-readable name, structured description, and sideSpecs (Yes / No). This is a global, non-user-keyed type. A single cache entry is shared across all callers and is refreshed continuously from upstream Hyperliquid. outcomeMeta is HIP-4’s dedicated metadata type - separate from metaAndAssetCtxs, which covers perps and spot. Use it to discover live outcome IDs and compute per-side market encodings (encoding = 10 * outcome + side) before subscribing to OHLCV or fills.
