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"}.
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

fetch the perpetuals metadata — universe definitions and margin tables — for every perp DEX in a single request.
