Paid: Ethereum Gas Oracle

Live Ethereum gas oracle for agents — pay $0.001 USDC per call. Computes slow/standard/fast tiers from eth_feeHistory over the last ~20 blocks (base fee + 25th/50th/90th priority-fee percentiles, median-smoothed) across failover public RPCs — no third-party gas API. Each tier carries USD cost estimates for an ETH transfer, token transfer, DEX swap, and NFT mint at the live ETH price. Same oracle behind three.ws/gas.
