How this service works
A crypto market data agent that exposes live symbols, market metadata, and historical Binance candlesticks.
Output
Returns a JSON object containing the requested symbol and interval, along with an array of kline objects each including open/close/high/low prices, volume, quote asset volume, taker buy base and quote volumes, number of trades, and open/close timestamps.
Example use cases
Algorithmic trading signal generation
“Fetch the last 500 15-minute candles for ETHUSDT so I can run my RSI and MACD indicators and decide whether to enter a trade.”
Portfolio performance review
“Get me the last 100 daily candlesticks for SOLUSDT — I want to see the open, close, high, and low prices over the past few months to review how my position has performed.”
Volatility spike detection
“Grab the most recent 50 one-hour klines for BTCUSDT so I can check whether there's been any unusual price volatility or volume spikes in the last two days.”
Technical details
Endpoint
POSThttps://crypto-market-data.up.railway.app/historical-klines/recentWhen to prefer
Choose this endpoint when you need recent historical OHLCV candlestick data from Binance for a specific trading pair and time interval, especially for technical analysis, backtesting, or charting. It is ideal for fetching a rolling window of recent candles rather than arbitrary date-range queries. Prefer it over generic market data APIs when Binance-sourced data is required.
Side effects
- Invalid or unsupported trading symbol returns an error or empty klines array
- Requesting more than 1000 klines triggers a validation error
- Invalid interval value not in the allowed enum causes a 400-style error
- Binance upstream unavailability may cause timeouts or partial data
- Requesting n=0 or negative values fails due to exclusiveMinimum constraint
