How this service works
Machine-payable x402 utilities for hashing, Base64, UUID generation, unit and timezone conversion, realtime crypto market data, webpage/document extraction, URL-to-Markdown, metadata, RAG ingestion and deterministic website change detection.
Output
A JSON response containing the current order book for the requested trading pair, including arrays of bids and asks with price levels and quantities, sourced in real time from Coinbase Exchange.
Example use cases
Pre-trade liquidity check
“Before I place a large ETH-USD buy order, can you pull the current order book so I can see how much liquidity is available and at what price levels?”
Real-time spread monitoring
“What's the current bid-ask spread for SOL-USD? Grab the live order book for me.”
Arbitrage opportunity research
“Can you fetch the order book for ETH-USDC so I can compare the bids and asks against another exchange I'm watching?”

Endpoint
POSThttps://x402-gateway-production-1f21.up.railway.app/crypto/book?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need real-time order book depth (bids and asks) for a Coinbase-listed trading pair and want a machine-payable, per-call micro-payment model via x402 without managing API keys or subscriptions. Prefer it for one-off or infrequent order book snapshots where pay-per-use is more cost-effective than a subscription feed.
Side effects
- Invalid product_id format (must match pattern like BTC-USD) returns a validation error
- Unsupported or delisted trading pair returns a not-found or empty response
- Payment failure via x402 protocol results in a 402 response and no data returned
- Downstream Coinbase Exchange API unavailability causes a timeout or 5xx error
