How this service works
Live order book depth and liquidity (bid/ask walls, spread, imbalance) for any crypto pair. For execution and slippage-aware agents. Free source. $0.01 USDC via x402 on Base. SYNTHORA.
Output
Returns real-time order book data including bid and ask price levels (walls), best bid/ask spread, and order book imbalance metrics for the requested trading pair, scoped to the specified depth limit. Useful for slippage estimation and execution planning.
Example use cases
Slippage check before large trade
“Before I execute a $200k buy of ETH/USDC, pull the live order book and tell me how deep the asks are — I need to know how much slippage I should expect and whether there are any big sell walls I'd be chewing through.”
Crypto arbitrage liquidity scan
“Check the current bid/ask spread and order book depth for SOL/USDT right now — I'm running an arbitrage strategy and I need to know if there's enough liquidity on both sides to make the trade worth it without moving the market.”
Detect large buy or sell walls
“Look up the order book for BTC/ETH with about 100 levels of depth and flag any unusually large bid or ask walls — I want to know if someone has a big limit order sitting out there that could act as support or resistance before I make my next move.”
Technical details
Endpoint
POSThttps://orderbook-liquidity.hergertsynthora.com/serviceWhen to prefer
Use this endpoint when an AI agent needs real-time order book depth and liquidity metrics for crypto execution decisions, slippage estimation, or market microstructure analysis. Prefer it when you need bid/ask walls and imbalance data rather than just a last price or OHLCV data. The free first 3 calls per wallet and no-charge-on-upstream-failure policy makes it low-risk for exploratory use.
Side effects
- Unknown or unsupported trading pair symbol returns an error or empty result
- Upstream exchange feed failure — no charge applied per stated policy
- Invalid limit parameter (non-integer or out-of-range) may return a validation error
- Network timeout or service unavailability returns a 5xx error
- Wallet address missing or malformed in X-WALLET header may block free-tier access
