How this service works
Real-time cryptocurrency spot price in USD, aggregated as the median across Coinbase, Binance and Kraken with cross-exchange spread. Supports BTC, ETH, SOL. Deterministic multi-source aggregation for trading and treasury agents.
Output
Returns the real-time median spot price of the requested cryptocurrency in USD, aggregated from Coinbase, Binance, and Kraken, along with per-exchange prices and the cross-exchange spread.
Example use cases
Real-time treasury valuation update
“Can you check what Bitcoin is trading at right now across Coinbase, Binance, and Kraken? I need the median price to update our treasury holdings for the financial report.”
DeFi liquidation price monitoring
“What's Solana's current median spot price? I want to make sure we're tracking it across all three major exchanges so we can set accurate liquidation thresholds for our protocol.”
Arbitrage opportunity detection
“Pull the latest ETH price from Coinbase, Binance, and Kraken for me — I'm specifically interested in seeing the cross-exchange spread so I can spot any profitable arbitrage windows.”
Technical details
Endpoint
GEThttps://data.japanagent.dev/crypto/price?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a deterministic, multi-source aggregated crypto price (median across Coinbase, Binance, Kraken) rather than a single-exchange feed, which is ideal for trading decisions, treasury accounting, or DeFi logic that requires a manipulation-resistant reference price. Best for BTC, ETH, and SOL only.
Side effects
- Invalid symbol (not BTC, ETH, or SOL) — returns 400 or validation error
- Missing required 'symbol' query parameter — returns error
- One or more exchanges temporarily unavailable — median may be computed from fewer sources
- Payment required / insufficient USDC balance — returns 402 error
- Rate limiting or network timeout — returns 5xx error
