How this service works
Stellar Top of order book: Return the best bid and ask levels from the public order book. Coinbase Exchange public USD market data; not investment advice.
Output
Returns the top of the XLM-USD (or specified product) order book from Coinbase Exchange, including the best bid price, best ask price, and associated quantities at those price levels, giving a real-time snapshot of the tightest available market prices.
Example use cases
Live XLM price check before trading
“What's the top of the order book for XLM-USD right now — what's the best bid and ask I can get?”
Monitoring XLM spread for arbitrage
“Keep an eye on the XLM-USD spread on Coinbase and tell me when the difference between the best bid and ask tightens below $0.001.”
Pre-trade price validation
“Before I place my Stellar buy order, can you pull the current best ask price for XLM-USD from Coinbase so I know what to expect?”
Technical details
Endpoint
POSThttps://market.datapackvibe.com/x402/demand-market-stellar-orderbook-top?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need a fast, low-cost real-time snapshot of the best bid and ask for XLM-USD (or another Coinbase USD pair) without needing the full order book depth. Ideal for pre-trade checks, spread monitoring, or price-awareness in agentic trading workflows. If you need full order book depth or historical data, look for alternative endpoints.
Side effects
- Invalid product ID returns an error — only Coinbase USD-denominated products are supported
- Network or upstream Coinbase API outage may cause timeouts or 5xx errors
- Stale data if Coinbase market data feed is delayed
- Payment failure (insufficient USDC balance) returns a 402 error before data is returned
