How this service works
[PerCall] Order book snapshot for a trading pair: top 10 bids and asks with quantities. Data sourced live from Binance public API.
Output
Returns a JSON order book snapshot with two arrays: 'bids' and 'asks', each containing the top 10 price levels with their corresponding quantities, sourced live from Binance.
Example use cases
Spread analysis for trading bot
“Get me the current order book depth for ETHUSDT so I can calculate the bid-ask spread and decide whether to place a limit or market order.”
Liquidity check before large trade
“Before I execute a big buy of SOLUSDT, can you grab the live order book to see how much liquidity is available in the top 10 ask levels?”
Arbitrage opportunity detection
“Fetch the order book snapshot for BNBUSDT right now — I want to compare the top bids and asks against another exchange to spot any arbitrage gaps.”
Technical details
Endpoint
GEThttps://percall.kimi.pro/api/x402/depth/:symbolWhen to prefer
Use this endpoint when you need a real-time snapshot of market depth for a specific Binance trading pair — especially when bid-ask spread, price impact estimation, or liquidity analysis at specific levels is required. Prefer this over a simple price quote when you need to see volume available at each price level, not just the last traded price.
Side effects
- Invalid or unsupported symbol returns an error (e.g. symbol not listed on Binance)
- Binance API downtime or rate limiting causes upstream failure
- Malformed symbol format (e.g. lowercase or incorrect pair notation) may return no data
- Payment failure (insufficient USDC or x402 handshake error) blocks the request
