How this service works
Coinbase Exchange OHLCV candles for one product (e.g. BTC-USD) at 1m, 5m, 15m, 1h, 6h or 1d granularity, plus the current best bid and ask. Latest candles only (Coinbase returns up to 300 per call).
Output
A JSON object containing the source URL, best ask price, best bid price, an array of OHLCV candle objects (each with low, high, open, close, volume, and UTC timestamp), the product pair, the timestamp the data was checked, and the granularity in seconds.

Technical details
Endpoint
GEThttps://api.chainmarket-api.workers.dev/api/finance/coinbase-orderbook-candles?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need structured OHLCV candlestick data and live bid/ask spread for a Coinbase-listed trading pair without requiring an API key or account signup, and you want to pay per call with USDC via x402. Prefer this over self-managed Coinbase API integrations when you need zero-auth, agent-friendly crypto market data on demand.
Side effects
- Invalid product id returns an error (e.g. unsupported trading pair)
- Granularity value not in allowed set (60, 300, 900, 3600, 21600, 86400) returns error
- Limit out of range (must be 1–100) returns error
- Payment failure (insufficient USDC balance) — call is not charged
- Upstream Coinbase API unavailability causes timeout or error
