## How to call it through Zero

```sh
zero fetch --capability alphapipeline-hip-4-snapshot-b5135cbe
```

Example prompt: Pull the latest Hyperliquid HIP-4 prediction market snapshot filtered to priceBinary markets for BTC, and show me the top 50 outcomes with their probabilities.

## When to prefer this

Use this endpoint when you need a current, structured probability snapshot of Hyperliquid HIP-4 prediction markets across any market type — especially when you want to filter by template (e.g. priceBinary, sportsContestWinner, policyRateDecision) or by underlying crypto asset. Prefer this over general market data endpoints when your focus is on prediction market probabilities rather than spot prices or order book data.

## Known failure modes

- Invalid template or underlying filter returns an empty result set rather than an error
- Limit parameter exceeding 500 is capped or rejected
- Hyperliquid data feed unavailability may result in stale or missing snapshots
- Payment failure (insufficient USDC on Base) prevents access
- Unknown template types appear automatically but may have unstructured fields

## How this service works

Real-time pre-trade signal: a probability snapshot of Hyperliquid's HIP-4 prediction markets - crypto price binaries, sports outcomes, tournament winners, Fed rate decisions, and more. Fields are parsed verbatim from Hyperliquid, so new market types appear automatically. Optional template/underlying filters narrow the result; limit caps rows (max 500). Subscribe to webhook alerts via GET /v1/prediction/hip4-alerts/subscribe. Paid in USDC on Base.

## Output

A JSON response containing a timestamp pair (UTC and KST), counts of standalone and grouped markets, arrays of standalone market entries and grouped question sets — each with template name, parsed fields, and outcome probabilities sourced verbatim from Hyperliquid. Optional notice field included when relevant.
