Endpoint
GEThttps://kr-x402-mvp.kgy5612.workers.dev/v1/token-price-oracles?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need real-time, multi-venue aggregated crypto token prices without managing API keys — ideal for autonomous trading agents, onchain bots, or any workflow that benefits from micropayment-gated access (x402/USDC on Base). Prefer this over single-exchange feeds when cross-venue price comparison or spread detection matters.
Side effects
- Invalid or unrecognized symbol returns missing key or error
- Payment failure via x402 (insufficient USDC balance on Base) results in 402 response blocking data
- Upstream exchange API downtime may cause stale or partial price data
- Malformed symbols query parameter (e.g. spaces instead of commas) may return empty or error response
