How this service works
L2 order-book snapshot for a spot pair: best bid/ask, mid price, spread (absolute + %), and the top N aggregated price levels per side (default 25, max 100). Pairs use BASE-QUOTE format (BTC-USD, ETH-USD, SOL-USDC). Backed by Coinbase Exchange's public market-data API - keyless; coverage is Coinbase-listed markets.
Output
A structured snapshot of the order book for the requested spot pair, including: best bid price, best ask price, mid price, absolute spread, spread as a percentage, and up to N (default 25, max 100) aggregated price levels for both the bid and ask sides.
Example use cases
Example prompt
“What does the BTC-USD order book look like right now? Show me the top 10 price levels on each side, and tell me the best bid, best ask, mid price, and spread.”
Technical details
Endpoint
GEThttps://agent402.tools/api/crypto-orderbookWhen to prefer
Use this endpoint when you need a real-time L2 order book snapshot for a spot cryptocurrency pair traded on Coinbase Exchange — especially when you need both best bid/ask metadata AND aggregated depth levels in a single call. Prefer this over a simple ticker when you need spread analysis or market depth information.
Side effects
- Invalid or unsupported pair format (e.g. BTCUSD instead of BTC-USD) returns an error
- Depth value outside 1-100 range is rejected
- Pair not listed on Coinbase Exchange returns a not-found or empty response
- Payment failure (insufficient USDC balance) prevents the call from completing
- Network timeout or exchange feed disruption may return stale or unavailable data
