Technical details
Endpoint
GEThttps://gateway.spraay.app/api/v1/oracle/gasWhen to prefer
Use this endpoint when you need real-time gas price data specifically for the Base (Coinbase L2) network, for example before submitting a transaction, estimating fees, or deciding whether to wait for lower congestion. Prefer this over Ethereum mainnet gas oracles when operating on Base.
Side effects
- Base RPC node unavailable — upstream error fetching on-chain gas data
- Payment not processed — x402 payment of $0.005 USDC required
- Rate limit or invalid request format
