## 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 nonvisceral-eloisa-mousily-ngrok-free-dev-75dfb653
```

Example prompt: What does the cross-venue BTC liquidation picture look like right now — are longs or shorts getting hit harder, is there a cascade alert, and what's the overall verdict?

## When to prefer this

Choose this endpoint when you need cross-venue BTC liquidation aggregation beyond single-exchange data — particularly when you want to detect cascade events spanning both OKX and Hyperliquid simultaneously, need long/short skew analysis, or require a pre-computed verdict rather than raw liquidation ticks. Prefer over single-venue Hyperliquid liquidation feeds when broader market coverage is needed.

## Known failure modes

- Venue API unavailability reduces reachable_venues count, potentially degrading signal quality
- Stale data if upstream OKX or Hyperliquid feeds are delayed
- Empty or partial per_exchange data if one venue is unreachable
- HTTP 402 if payment not provided or insufficient
- Rate limiting if called too frequently without valid payment

## How this service works

Cross-venue BTC liquidations aggregated across reachable venues (OKX + Hyperliquid; Binance/Bybit/Bitget/MEXC need API keys, excluded). Per-venue 1h long/short_liq_usd + n_events, aggregate totals, side_skew (-1 long-heavy, +1 short-heavy), cascade_alert, verdict (cascade/quiet/neutral). Liquidation-tape signal beyond single-venue HL.

## Output

Returns aggregate USD liquidation totals for the past 1 hour split by long and short sides, per-venue breakdown for OKX and Hyperliquid (liq_1h_usd, long_liq_usd, short_liq_usd, n_events), a side_skew value from -1 (long-heavy) to +1 (short-heavy), a boolean cascade_alert flag indicating whether liquidations exceed the cascade threshold, an overall verdict string (cascade/quiet/neutral), count of reachable venues, and a timestamp.
