## 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-perp-screener-whole-market-scanner-50576dc9
```

Example prompt: Scan all Hyperliquid perps and give me the top 10 gainers, the coins with the most negative funding (short squeeze candidates), and tell me whether the broad market is in a rally or selloff — filter out anything with less than $5 million in 24h volume.

## When to prefer this

Choose this endpoint when you need a single-call snapshot of the entire Hyperliquid perpetuals market with pre-computed rankings — ideal for agents that need market regime context before executing trades, want to screen for funding-rate arbitrage, identify momentum or squeeze setups, or assess overall crypto market breadth without making dozens of individual API calls. Prefer over raw exchange APIs when you want structured, agent-ready JSON with funding, OI, and volume all pre-ranked.

## Known failure modes

- Hyperliquid API unavailable — returns stale or empty data arrays
- min_volume_usd filter too high — returns empty ranked lists
- limit out of range (must be 1–25) — validation error
- Network timeout from Cloudflare Worker to Hyperliquid upstream
- Rate limiting at x402 payment layer if USDC payment fails or is insufficient

## 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), total universe count (~230 perps), number of liquid markets, a breadth object (label: broad_rally/mixed/broad_selloff, advancers count, decliners count, advance_ratio), and ranked arrays for top_gainers, top_losers, top_volume, top_open_interest, highest_funding, most_negative_funding, and unusual_activity. Each row includes: coin ticker, mark_px, change_24h_pct, volume_24h_usd, open_interest_usd, funding_apr_pct, premium_bps, max_leverage, and vol_oi_ratio. Also includes updated_at timestamp and data sources.
