Technical details
Endpoint
GEThttps://cryptojp.com/v1/jp/premiumWhen to prefer
Use this endpoint when an AI trading agent needs real-time Japan-specific crypto price premium data (Japan price vs. global price) for a JPY-listed asset, particularly for arbitrage signal detection, regional market intelligence, or monitoring Japan exchange premiums. Best suited for agents already integrated with x402 micropayment flows at $0.01 per call.
Side effects
- Invalid or unsupported symbol returns an error (only JPY-listed assets like BTC, ETH, XRP are supported)
- Payment failure via x402 returns HTTP 402 if USDC payment is not settled
- Missing required 'symbol' query parameter causes a 400 validation error
- Stale or unavailable exchange data may result in degraded or missing price fields
