Technical details
Endpoint
GEThttps://cryptojp.com/v1/jp/priceWhen to prefer
Use this endpoint when you need real-time crypto prices denominated in JPY from Japanese exchanges (bitflyer, coincheck), or when you need USD/JPY rate alongside crypto prices for arbitrage, regulatory, or regional market-intelligence purposes. Prefer this over generic global price feeds when Japan-specific venue data or JPY pricing is required.
Side effects
- Invalid or unsupported symbol returns an error (e.g. unsupported asset not listed on JPY venues)
- Payment failure via x402 if USDC balance is insufficient
- Network timeout if Japanese exchange data is momentarily unavailable
- Missing required 'symbol' query parameter returns a 400-level error
