## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability hyperliquid-on-chain-markets-data-bed59e13 -d '<json body>'
```

Example prompt: Pull the latest on-chain market data from Hyperliquid for BTC perps, including recent fills and any active liquidation risk — I want to understand what's happening on-chain right now.

## When to prefer this

Choose this endpoint when you need first-party, operator-neutral Hyperliquid on-chain trading data without requiring an account or API key — particularly for perp fills, position lifecycle analysis, liquidation risk, leaderboard data, or HIP-4 prediction markets. It is ideal for agents that need trustworthy data sourced directly from Hyperliquid's own node fills ledger rather than aggregated third-party feeds. Pay-per-call via x402 on Base makes it suitable for low-frequency or exploratory queries without subscription commitment.

## Known failure modes

- Invalid or missing body payload returns 400 Bad Request
- Insufficient x402 payment or wrong chain (must be Base USDC) returns 402 Payment Required
- Unsupported market type or asset filter returns 404 or empty result set
- Rate limiting or node data lag may cause stale or delayed responses
- Malformed JSON body returns parsing error

## How this service works

First-party Hyperliquid trading intelligence: perp fills, position lifecycles, all-wallet leaderboards, trader cohorts, liquidation risk and HIP-4 prediction markets - computed from our own node_fills ledger plus the Hyperliquid public info API (no third-party data source). Free discovery (/healthz, /v1/stats, /.well-known/x402, /v1/openapi.json) and free sample routes (/v1/markets/overview, /v1/assets); all other API calls are $0.001 USDC per request via x402 on Base (no account, no API key).

## Output

Returns structured JSON containing on-chain Hyperliquid market data — which may include perpetual fill records, position lifecycle events, leaderboard rankings by wallet, trader cohort breakdowns, liquidation risk scores, and HIP-4 prediction market stats — all sourced from first-party node_fills ledger and Hyperliquid's public info API.
