# outcomeMeta | Hyperliquid Info API
> Hyperliquid outcomeMeta: enumerate all active HIP-4 binary outcome markets on HyperCore.
1 per call
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](/pricing-calculator?endpoint=%2Fapi-reference%2Fhyperliquid-info%2Foutcome-meta).
* 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
Content-Type: application/json
```
## Request
Always `"outcomeMeta"`.
### Example
```bash cURL theme={null}
curl -X POST https://hypercore.goldrushdata.com/info \
-H "Authorization: Bearer $GOLDRUSH_API_KEY" \
-H "Content-Type: application/json" \
-d '{
"type": "outcomeMeta"
}'
```
```typescript TypeScript theme={null}
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();
```
```python Python theme={null}
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
```json theme={null}
{
"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 of active outcome markets.
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`).
Human-readable label for the market - for example, `"Recurring"` for repeating daily/weekly markets.
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. |
Tradeable sides of the outcome, ordered by side index. For binary outcomes, index 0 is `Yes` and index 1 is `No`.
Side label - typically `"Yes"` or `"No"` for binary outcomes.
