## 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-cohort-bias-analysis-d55187e1 -d '<json body>'
```

Example prompt: What's the current directional bias across trader cohorts on Hyperliquid — are most wallets running long or short on ETH perps, and is there any crowding risk I should know about?

## When to prefer this

Use this endpoint when you need trader sentiment segmented by cohort (e.g., whale vs retail) on Hyperliquid perps — especially when looking for directional crowding signals, contrarian indicators, or aggregate positioning data. Prefer this over generic on-chain analytics when you specifically need Hyperliquid-native, first-party fill data with cohort segmentation.

## Known failure modes

- HTTP 402 if free quota is exhausted and no USDC payment is attached — pay-per-call x402 required
- Malformed or missing required body fields return 400-level errors
- Upstream Hyperliquid public info API outage may cause stale or unavailable data
- Unknown cohort type or asset identifiers may return empty result sets
- Rate limiting if too many calls are made without payment

## How this service works

Operator-neutral Hyperliquid trading intelligence — perp fills, position lifecycles, all-wallet leaderboards, trader cohorts, liquidation risk and prediction markets. Every endpoint is FIRST-PARTY: computed from our own node_fills ledger and the Hyperliquid public info API (no third-party data source). Free quota, then HTTP 402 (x402: pay-per-call in USDC, no account, no key).

## Output

Returns cohort-segmented bias metrics showing the directional skew (long/short ratios, bias scores) across different trader groups on Hyperliquid perpetuals, derived from first-party node_fills ledger data. May include cohort labels, sentiment signals, and crowding indicators.
