## 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`):

## When to prefer this

Choose this endpoint when you need a broad, cross-market sweep of positioning shifts on Hyperliquid — specifically OI jumps and funding-rate flips — presented as clean signal lines without needing to parse raw tick data. Prefer it over single-market or single-metric endpoints when you want a cycle-over-cycle change view across all 320 markets in one call.

## Known failure modes

- No data available if Hyperliquid feed is temporarily unavailable
- Empty or minimal signals if no markets showed significant OI or funding changes in the last cycle
- Rate limiting or payment failure if USDC payment of $0.03 is not processed correctly via x402
- Stale data if the cycle snapshot has not yet refreshed

## How this service works

Where positioning changed: open-interest jumps and funding-rate flips across 320 markets, as ready-to-read lines. Falls back to the last hour when the current cycle is quiet, so the answer is never empty

## Output

A list of human-readable signal lines covering all 320 Hyperliquid perpetual markets, each line indicating where open interest jumped or dropped and where funding rates flipped compared to the previous cycle, enabling quick identification of significant positioning changes.
