Endpoint
GEThttps://kr-x402-mvp.kgy5612.workers.dev/crypto/price/ada-usd?utm_source=zero.xyzWhen to prefer
Choose this endpoint when your AI agent needs real-time ADA/USD price data from multiple venues simultaneously without managing individual exchange API keys, and when you want pay-per-call micropayment billing via x402 (USDC on Base) rather than a subscription. Ideal for onchain trading agents, DeFi bots, or portfolio trackers that need Cardano price data infrequently enough that per-call pricing is cheaper than a subscription.
