## 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-low-ranking-oi-perpetuals-feed-03d4946f
```

Example prompt: Show me the top 15 low open-interest perpetuals on Hyperliquid with at least $2M in 24h volume — I want to see which ones are gaining, their funding rates, and the overall advance/decline breadth right now.

## When to prefer this

Choose this endpoint when you need to screen Hyperliquid perpetuals specifically by low open interest — ideal for finding less crowded markets, momentum plays with high vol/OI ratios, or monitoring market breadth. Prefer over generic OHLCV or price endpoints when you need funding rates, advance/decline breadth, and OI-ranked filtering in one call. No API key required; pay $0.002 USDC per call via x402.

## Known failure modes

- Payment failure if USDC balance on Base is insufficient for the $0.002 per-call fee
- Hyperliquid API upstream outage causing stale or missing data
- Invalid query parameter values (limit outside 1-25, negative min_volume_usd) returning 400 error
- Empty result arrays if no contracts pass the min_volume_usd filter at given threshold
- Rate limiting or worker timeout on the Cloudflare Workers edge

## How this service works

Pay-per-call crypto microdata for trading/onchain AI agents via x402 (USDC on Base): Base gas, token risk, balances, multi-venue prices, Hyperliquid book/funding, kimchi premium. No API keys.

## Output

A JSON object containing: venue name (Hyperliquid), count of liquid markets, advance/decline breadth with label and ratio, total universe size, data sources, timestamp, and ranked arrays for top gainers (with coin, mark price, 24h change %, 24h volume USD, funding APR %, open interest USD, vol/OI ratio, premium bps, max leverage), top losers, top volume, highest/most-negative funding, unusual activity, and top open interest — all filtered to low-ranking OI contracts.
