Realtime

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.

Endpoint

POST https://hypercore.goldrushdata.com/info
Authorization: Bearer <GOLDRUSH_API_KEY>
Content-Type: application/json

Request

string

required

Always "outcomeMeta".

Example

curl -X POST https://hypercore.goldrushdata.com/info \
  -H "Authorization: Bearer $GOLDRUSH_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{
    "type": "outcomeMeta"
  }'

const response = await fetch("https://hypercore.goldrushdata.com/info", {
  method: "POST",
  headers: {
    "Authorization": `Bearer ${process.env.GOLDRUSH_API_KEY}`,
    "Content-Type": "application/json",
  },
  body: JSON.stringify({
    type: "outcomeMeta",
  }),
});

const { outcomes } = await response.json();

import os, requests

response = requests.post(
    "https://hypercore.goldrushdata.com/info",
    headers={"Authorization": f"Bearer {os.environ['GOLDRUSH_API_KEY']}"},
    json={"type": "outcomeMeta"},
)

outcomes = response.json()["outcomes"]

Response

{
  "outcomes": [
    {
      "outcome": 123,
      "name": "Recurring",
      "description": "class:priceBinary|underlying:HYPE|expiry:20260310-1100|targetPrice:34.5|period:3m",
      "sideSpecs": [
        { "name": "Yes" },
        { "name": "No" }
      ]
    }
  ]
}

Field descriptions

array<object>

Array of active outcome markets.

Show properties

int

Integer outcome ID. Combine with a side index to compute the tradeable market encoding: encoding = 10 * outcome + side. An outcome with Yes (side 0) and No (side 1) yields two encodings (e.g. 1230 and 1231).

string

Human-readable label for the market - for example, "Recurring" for repeating daily/weekly markets.

string

Pipe-delimited spec describing the market. Parse it once to extract the full definition:

Field	Example	Meaning
`class`	`priceBinary`	Market class (binary outcome on a price threshold).
`underlying`	`HYPE`	Asset the outcome resolves against.
`expiry`	`20260310-1100`	Resolution timestamp, `YYYYMMDD-HHMM` UTC.
`targetPrice`	`34.5`	Threshold the underlying is compared against at expiry.
`period`	`3m`	Recurrence cadence for repeating markets.

array<object>

Tradeable sides of the outcome, ordered by side index. For binary outcomes, index 0 is Yes and index 1 is No.

Show properties

string

Side label - typically "Yes" or "No" for binary outcomes.

metaAndAssetCtxs

fetch the full Hyperliquid perpetuals market universe with live per-asset trading context.

spotMetaAndAssetCtxs

fetch the spot universe metadata, token configuration, and live market data in a single call.

settledOutcome

retrieve resolution details for a settled HIP-4 binary outcome market on HyperCore.

spotMeta

fetch the spot universe metadata and full token configuration without live market context.

allPerpMetas

perpetuals universe and margin tables for every perp DEX in one request.
