Endpoint
GEThttps://kr-x402-mvp.kgy5612.workers.dev/api/price?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need real-time, multi-venue aggregated crypto prices (Binance + Coinbase) in a single call with no API key required, paying only $0.003 USDC per call via x402. Ideal for AI trading agents, portfolio bots, or price-alert systems that need cross-venue price comparison and 24h change data in one lightweight request. Prefer over single-venue price feeds when cross-exchange spread or consensus pricing matters.
