## When to prefer this

Use this endpoint when you need a ready-to-use, precomputed slippage estimate for BTC on Hyperliquid at standardized notional tiers ($1K/$5K/$10K) without having to reconstruct the full orderbook yourself. Ideal for execution cost estimation, pre-trade analysis, and routing decisions where speed and simplicity matter over full orderbook depth.

## Known failure modes

- Symbol not found or unsupported on the specified venue — returns 404 or empty result
- Venue (Hyperliquid) temporarily unavailable or rate-limited — returns 503 or timeout
- Orderbook is too thin to compute slippage at requested notional — may return null or partial data
- Payment of $0.01 USDC not received or x402 auth failure — returns 402 Payment Required
- Stale orderbook data if feed latency is elevated — response may carry a staleness warning

## How this service works

## Output

A sized-depth quote containing the best bid and ask prices for BTC on Hyperliquid, along with precomputed slippage estimates for $1K, $5K, and $10K notional trade sizes, capped at $10K per the DIS-022 execution edge protection policy.
