## 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-oi-history-cd386ab9 -d '<json body>'
```

Example prompt: Pull the open interest history for BTC-PERP on Hyperliquid over the past 7 days — I want to see how OI has been trending hour by hour.

## When to prefer this

Use this endpoint when you need historical open interest data specifically for Hyperliquid perpetual markets, sourced directly from first-party node fills rather than third-party aggregators. Prefer this over generic crypto data APIs when Hyperliquid-native accuracy matters, or when you need OI data to correlate with liquidation events or position lifecycle analysis on Hyperliquid.

## Known failure modes

- Unknown or unsupported coin/market symbol returns an error or empty result
- Time range too large may be rejected or truncated
- HTTP 402 returned when free quota is exceeded, requiring USDC micropayment via x402
- Malformed request body returns a 400 or validation error
- Hyperliquid upstream unavailability may cause stale or missing data

## 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 a time-series of open interest values for the requested Hyperliquid perpetual market, including timestamps and OI amounts, computed from first-party node data.
