Endpoint
POSThttps://agentshelf.syntexa.ch/v1/crypto-orderbook?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a fast, multi-exchange-aggregated order book snapshot for spot crypto markets with best bid/ask, mid, spread, and spread in bps all in one call. It is ideal when you do not have direct exchange API keys, want automatic exchange fallback across Coinbase, Kraken, OKX, and Binance, and need a normalized symbol format. Prefer alternatives if you need full historical order book data, streaming WebSocket updates, or derivatives/futures markets.

- All four exchanges (Coinbase, Kraken, OKX, Binance) unavailable results in a 503 or error response
