How this service works
Paid market-intelligence API over x402
Output
A JSON object containing an array of candles, each with open/high/low/close prices, VWAP, dollar volume, doji boolean, upper and lower wick percentages, candle body percentage, and a forming-candle flag. Also includes metadata: asset name, interval, candle count, data source label, as-of timestamp, gap flags, consolidation status, and a disclaimer noting the multi-exchange aggregation.
Example use cases
Hourly candle review for BTC
“Get me the last 100 one-hour candles for BTC-USD including VWAP and wick percentages — I want to see if there are any doji patterns forming.”
Daily swing trade setup check
“Fetch the last 30 daily candles for ETH-USD with dollar volume and gap flags so I can identify any breakout setups over the past month.”
4-hour candle batch for algo signal
“Retrieve 200 four-hour OHLC candles for SOL-USD consolidated from multiple exchanges — I need the open, high, low, close, and VWAP values for a momentum model I'm running.”
Technical details
Endpoint
GEThttps://kronossignals.com/api/v1/ohlc/%7Basset%7DWhen to prefer
Choose this endpoint when you need structured OHLC candlestick data aggregated from multiple top exchanges (Binance + Coinbase) with enriched metadata like VWAP, wick ratios, doji detection, and gap flags — particularly when building technical analysis pipelines or feeding ML models that require clean, consolidated candle series rather than raw single-exchange feeds.
Side effects
- Unsupported asset symbol returns an error or empty candle array
- Limit exceeding 200 is rejected by schema validation
- Interval value outside 1h/4h/1d enum is rejected
- Payment failure via x402 results in 402 response blocking data delivery
- Baseline insufficient flag set to true when exchange data is sparse
- Gap flags non-null indicate missing intervals in the candle series
