How this service works
Live L2 order book for a crypto perp market: aggregated bids and asks with price, size and resting-order count per level, plus the best bid/ask spread, spread % and mid price. Real-time market-depth snapshot for a coin (BTC, ETH, SOL, and more); pass `depth` for how many price levels per side. Data source: Hyperliquid (dYdX fallback).
Output
A JSON snapshot containing aggregated bid and ask levels (each with price, size, and resting order count), the best bid price, best ask price, raw spread, spread as a percentage, and mid price. Sourced from Hyperliquid with dYdX as a fallback.
Example use cases
Pre-trade liquidity check for large BTC order
“Before I place a large BTC perp trade, can you show me the order book depth — give me 50 levels on each side so I can see where the liquidity thins out and estimate my slippage?”
Spread monitoring for ETH perp arbitrage
“What's the current bid-ask spread and mid price on the ETH perpetual market? Show me the top 5 price levels so I can see if there's an arb opportunity.”
Real-time SOL market depth dashboard
“Grab the full L2 order book for SOL perp with 100 price levels per side — I want to see the resting order counts and sizes at each level for my market depth chart.”

Endpoint
POSThttps://crypto.openverbs.com/v1/orderbook?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a real-time, granular L2 order book snapshot for a crypto perpetual futures market from on-chain DEX sources (Hyperliquid/dYdX), especially when you need per-level resting order counts, spread metrics, and mid price in a single call. Prefer over generic price feeds when market depth and liquidity structure matter, such as for pre-trade analysis, slippage estimation, or arbitrage detection.
Side effects
- Unsupported coin symbol returns an error or empty book
- Depth value out of range (>100 or <1) returns a validation error
- Hyperliquid and dYdX both unavailable causes a service error
- Network timeout if upstream DEX data feed is slow
- Stale data if the upstream source has a temporary feed interruption
