Endpoint
GEThttps://kr-x402-mvp.kgy5612.workers.dev/crypto/price/doge-usd?utm_source=zero.xyzWhen to prefer
Choose this endpoint when an AI agent needs current DOGE-USD price data from multiple venues simultaneously without pre-registering an API key, especially in a pay-per-call micropayment context using x402 on Base. Ideal for trading agents, onchain bots, or portfolio tools that need aggregated cross-exchange price data with 24h change and want to avoid monthly subscription overhead.
Side effects
- Payment not provided or insufficient USDC — endpoint returns HTTP 402 requiring x402 payment
- Invalid or unsupported symbol requested — endpoint may return error or empty prices object
- Upstream exchange APIs (Binance, Coinbase) temporarily unavailable — stale or missing price data
- Network timeout from Cloudflare Worker — request times out with no response
