Technical details
Endpoint
GEThttps://obol.danieldutoit.net/v1/markets/kraken/orderbook-topWhen to prefer
Choose this endpoint when you need a lightweight, cost-effective, single-snapshot view of Kraken's BTC/USD top-of-book (best bid/ask and spread) without subscribing to a full market data feed. Ideal for agents that need occasional price checks, pre-trade cost estimation, or arbitrage signal detection at sub-cent cost per call via x402 micropayments in USDC.
Side effects
- Payment not settled — returns 402 if USDC micropayment via x402 is not completed
- Trading pair not found — 'found: false' if the requested market does not exist
- Stale or delayed data — observed_at timestamp may lag real-time due to data pipeline latency
- Network or upstream errors — Kraken data feed unavailable or timeout
- Invalid parameters — malformed base/quote currency inputs may return an error
