How this service works
OHLC candles for a coin: days 1 (30-min candles), 7 or 14 (4-hour), 30 / 90 / 180 / 365 (daily), in any vs currency. Returns aligned {time, open, high, low, close} bars plus the window's high/low/first/last and % change. The candle sibling of crypto-history, which returns close-only points: use OHLC for technical indicators, range/volatility work and charting. Cached in-process for 60 seconds.
Output
Returns an array of OHLC bars each with open, high, low, close prices and a UTC timestamp, plus a summary object with overall high, low, first, last prices and percentage change. Also includes metadata: coin id, number of days, count of bars, currency, granularity (e.g. 4h), data source (CoinGecko), fetchedAt timestamp, and a cached flag.

Technical details
Endpoint
GEThttps://agent402.tools/api/coin-ohlcWhen to prefer
Choose this endpoint when you need structured OHLC candlestick price history for a specific cryptocurrency over a defined lookback window, especially when you want a built-in price summary (first, last, high, low, changePct) alongside the raw bars. Ideal for charting, backtesting signals, or reporting on price movement without building your own aggregation. Prefer over raw tick data sources when 4h or daily granularity suffices and pay-per-call USDC pricing with no API key is acceptable.
Side effects
- Unknown coin id returns error or empty response
- Unsupported days value outside allowed set (1,7,14,30,90,180,365) may return error
- Unsupported currency code returns error
- Rate limiting or upstream CoinGecko unavailability causes failure
- Payment of 0.008 USDC required per call; unpaid requests are rejected with 402
