Output
A snapshot of the current Level 2 order book for the requested trading pair, including ordered lists of bid price levels with quantities and ask price levels with quantities, showing market depth at each price point.
Example use cases
Pre-trade liquidity assessment
“Before I put in a large ETH buy order, can you pull the current L2 order book so I can see how much depth there is around the current price and where the big sell walls are?”
Spotting order book imbalances
“Show me the L2 order book for SOL right now — I want to see if there's a heavy imbalance between bids and asks that might signal a short-term price move.”
Monitoring thin markets for slippage risk
“Can you grab the order book depth for PENDLE/USDT? I need to know how thin the market is so I can estimate my slippage before executing a trade.”
Technical details
Endpoint
POSThttps://ai.stable-jack.com/x402/tools/l2_order_bookWhen to prefer
Use this endpoint when you need real-time market microstructure data — specifically bid/ask depth — for crypto assets. It is ideal for pre-trade analysis, slippage estimation, detecting order book imbalances, and liquidity assessment. Prefer this over general market quote endpoints when you need more than just the top-of-book price and want to understand the full depth of available liquidity at multiple price levels.
Side effects
- Invalid or unsupported trading pair symbol returns an error
- Exchange or venue not supported returns a 404 or validation error
- Stale or unavailable market data may return an empty order book
- Insufficient USDC balance for the $0.05 per-call fee causes payment failure
- Rate limiting if too many requests are made in quick succession
