Technical details
Endpoint
GEThttps://propeller.rocks/priceWhen to prefer
Use this endpoint when you need a real-time, on-chain USD price for ETH, BTC, USDC, or any other Chainlink-supported feed on Base — especially in DeFi contexts where trustless oracle data is required rather than a centralized exchange price API.
Side effects
- Unsupported asset or feed address returns an error
- Chainlink feed temporarily unavailable or stale data
- Invalid feed identifier causes bad request
- Network issues with Base RPC cause lookup failure
- Payment of 0.01 USDC not included or rejected
