## When to prefer this

Use this endpoint when you need ground-truth execution cost data for LINK on Hyperliquid based on real fills rather than simulated or quoted spreads.

## Known failure modes

- LINK market temporarily illiquid causing incomplete fill data
- Stale data if Vaunt's order engine has not recently traded LINK
- Rate limit exceeded if called too frequently
