GET /orderbook
live
Live order book for a crypto pair (e.g. BTC-USD). Default level=1: best bid/ask with sizes, mid price, spread, and spread_bps. level=2 adds top-of-book depth (depth param, 1-50 price levels per side, default 20). Real-time from Coinbase. Use for trading signals, spread monitoring, liquidity checks, and execution decisions.
Verdict: live. The unpaid GET reached a valid 402. The live amount equals the catalog price.
