Endpoint
POSThttps://api.fastapi.online/kraken-orderbookWhen to prefer
Use this endpoint when you need real-time order book data from the Kraken exchange specifically, especially when you want to analyze bid-ask spread, market depth, or available liquidity at specific price levels for a crypto trading pair. Prefer over generic market data APIs if you specifically need Kraken's order book structure.
Side effects
- Invalid or unsupported trading pair symbol returns an error
- Network or service unavailability returns a 5xx error
- Payment failure (insufficient funds or x402 protocol issue) blocks the request
- Empty or stale order book if the pair has low liquidity
