How this service works
Coinbase Exchange (US spot) order book for one product: best bid and ask, spread, USD depth within 1% and 2% of mid (aggregated level-2 levels only), 24h base volume, 24h RFQ (institutional request-for-quote) volume, last price and 24h high/low. Coinbase Exchange data only, not Coinbase Advanced or other venues.
Output
Returns a JSON object with the last traded price, best bid, best ask, mid price, spread percentage, 24h high/low/open, 24h base volume, 30d base volume, order book depth in USD within 1% and 2% of mid, RFQ volume, book sequence number, and a checkedAt timestamp — all sourced live from the Coinbase Exchange order book.
Example use cases
Real-time crypto price alert bot
“Check the current ETH-USD mid price on Coinbase and tell me if it's below $3,000 so I know whether to set a buy order.”
Order book liquidity analysis
“How much USD liquidity is sitting within 1% and 2% of the current BTC-USD mid price on Coinbase? I want to know if the market can absorb a large trade.”
Daily crypto market summary
“Give me a snapshot of BTC-USD on Coinbase for today — the 24-hour high, low, open, last price, and total volume traded.”
Technical details
Endpoint
GEThttps://api.chainmarket-api.workers.dev/api/crypto/coinbase-spot-exchange?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need real-time Coinbase spot price data with full order book context (bid/ask spread, depth within 1-2%), 24h and 30d volume — especially when you want a pay-per-call approach with no API key or signup. Prefer over generic price aggregators when Coinbase-specific pricing or liquidity is required.
Side effects
- Invalid or unsupported product ID returns an error (e.g. misspelled pair like 'BTC-US')
- Network or upstream Coinbase API outage may return a 5xx error
- Rate limiting or payment failure results in a 402 response and no charge
- Illiquid or delisted trading pairs may return incomplete depth data
