How this service works
OHLCV candles for a Coinbase trading pair (BTC-USD) at 1m, 5m, 15m, 1h, 6h or 1d granularity, up to 300, newest first, from Coinbase Exchange public market data. Prices are that venue's trades only. Information only, not financial advice.
Output
Returns a JSON object with the trading pair name, granularity, count, and an array of candles sorted newest-first. Each candle includes timestamp, open, high, low, close, and volume. Also includes source attribution, checkedAt timestamp, and a disclaimer that data is informational only.
Example use cases
Technical analysis for trading bot
“Get me the last 100 one-hour candles for ETH-USD — I need the open, high, low, close, and volume so I can run my RSI and MACD indicators.”
Daily price range monitoring
“Fetch the daily candles for SOL-USD for the past 30 days so I can see how the price range and volume have been trending.”
Short-term volatility check
“Give me the last 50 five-minute candles for BTC-USD — I want to see if there was a big price spike in the last few hours.”
Technical details
Endpoint
GEThttps://api.sitecheck-api.workers.dev/api/crypto/candles?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need structured OHLCV candlestick data for a Coinbase-listed trading pair, especially for technical analysis, charting, or time-series price history. Prefer it over generic price endpoints when you need historical intervals with volume data across multiple granularities. Ideal for agents that need pay-per-call access without managing exchange API keys.
Side effects
- Invalid pair symbol returns an error or empty candle array
- Granularity value not in allowed enum (1m, 5m, 15m, 1h, 6h, 1d) causes a validation error
- Limit out of range (outside 1-300) may return an error or be clamped
- Network or Coinbase upstream outage results in a timeout or 5xx error
- Payment failure due to insufficient USDC balance blocks the request
