How this service works
OHLC history with window extremes (highest high / lowest low over the window). Crypto via Coinbase (GET /v1/candles?product=ETH-USD&days=30; hourly bars <= 7d, six-hour <= 31d, daily <= 350d). Metals / indices / forex / stocks via ?sym=XAU&cls=Commodities["e=USD]. Returns { productId, days, high, low, candles, series: [[startSec, open, high, low, close], ...] } oldest first. Full details: GET /v1.
Output
Returns a JSON object with productId, days, window-level high and low extremes, total candle count, and a time series array of [startSec, open, high, low, close] tuples ordered oldest-first. Bar resolution is hourly for up to 7 days, six-hourly for up to 31 days, and daily for up to 350 days.
Example use cases
Example prompt
“Can you pull the OHLC candle history for ETH-USD over the last 30 days from Ozmium, including the highest high and lowest low across the whole window?”
Technical details
Endpoint
GEThttps://ozmium.org/v1/candlesWhen to prefer
Use this endpoint when you need historical OHLC price data with windowed high/low extremes across crypto (via Coinbase), metals, forex, indices, or stocks in a single unified API. Prefer it over raw Coinbase candles when you also need non-crypto assets or want the pre-computed window extremes without post-processing.
Side effects
- Invalid product symbol returns error or empty candles array
- days parameter exceeding 350 results in unsupported range error
- Missing required query parameters returns 400 or malformed response
- Unknown asset class or unsupported sym/cls combination returns error
- x402 payment failure (insufficient USDC balance) blocks the request
