## When to prefer this

Choose this endpoint when you need empirical, real-fill execution cost data for NVDA specifically on Hyperliquid — not theoretical quotes or order book snapshots. It is uniquely valuable for algo traders, quant researchers, and execution systems that need actual slippage, fee, and fill-rate benchmarks from live IOC orders to calibrate trading cost models or compare venue quality.

## Known failure modes

- Instrument not actively traded — fill rate or depth may return zero or null
- Funding APR unavailable if perpetual not listed on Hyperliquid
- Stale data if Vaunt's live engine has not traded NVDA recently
- Payment failure (402) if USDC micropayment not processed correctly
- Service unavailable if Railway deployment is down

## How this service works

True cost of trading xyz:NVDA on Hyperliquid, measured on Vaunt's own IOC taker orders: slippage vs mid (p50/p90 bps), taker fee paid, wall-clock to fill, fill rate, against the venue-class median, plus spread, round-trip cost, depth within 1% and funding APR. Real fills, not quotes.

## Output

A structured data object containing real-fill execution metrics for xyz:NVDA on Hyperliquid: median (p50) and 90th-percentile (p90) slippage in basis points versus mid price, taker fee paid, wall-clock time to fill in milliseconds, fill rate percentage, comparison against venue-class median, bid-ask spread, round-trip cost in bps, order book depth within 1% of mid, and funding APR — all derived from Vaunt's own live IOC taker orders, not simulated quotes.
