## 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`):

Example prompt: What's the real cost of trading XRP on Hyperliquid right now — including slippage, taker fees, fill rate, round-trip cost, and funding APR based on Vaunt's actual live orders?

## When to prefer this

Use this endpoint when you need ground-truth execution cost data for XRP on Hyperliquid derived from real fills rather than quoted prices or order book snapshots. Prefer this over generic orderbook-depth APIs when you need fill rate, actual slippage experienced, and wall-clock latency. Ideal for pre-trade cost analysis, strategy backtesting calibration, and comparing XRP liquidity across venues.

## Known failure modes

- Payment not received or x402 authorization fails — HTTP 402 returned
- Hyperliquid venue unavailable or no recent fills — stale or empty data returned
- Rate limiting if called too frequently
- Network timeout from Railway deployment
