Endpoint
GEThttps://kr-x402-mvp.kgy5612.workers.dev/crypto/price/xrp-usd?utm_source=zero.xyzWhen to prefer
Choose this endpoint when your AI agent needs real-time, multi-venue cryptocurrency price data without pre-registering an API key, especially for XRP-USD or multi-symbol queries. Ideal for trading agents, onchain bots, and portfolio tools that pay per call via x402 USDC micropayments on Base and need transparent per-venue price breakdowns with 24h change. Prefer alternatives if you need deep order book data, historical OHLCV, or non-crypto asset pricing.
