How this service works
Real-Time EIP-1559 Gas Estimation and Fee History Oracle for Base Mainnet, payable via x402.
Output
A JSON object containing the network name (e.g. 'base-mainnet'), the current base fee in gwei, the suggested EIP-1559 max fee in gwei, and the suggested priority fee (miner tip) in gwei for the requested speed tier.
Example use cases
Optimizing DeFi transaction cost
“Before I submit this swap on Base, what's the suggested max fee and priority fee for a standard-speed transaction right now so I don't overpay on gas?”
Instant transaction time-sensitive trade
“I need to get this transaction confirmed as fast as possible on Base Mainnet — what max fee and priority fee should I set for an instant submission?”
Budget-conscious slow transaction
“I'm not in a rush — what are the current gas fee recommendations for a slow transaction on Base so I can minimize costs?”
Technical details
Endpoint
POSThttps://baseshield-x402-ojil.vercel.app/v1/estimateWhen to prefer
Choose this endpoint when you need real-time, tiered EIP-1559 gas fee estimates specifically for Base Mainnet and want a simple speed-based abstraction (slow/standard/fast/instant) rather than computing raw fee parameters yourself. Prefer it over generic Ethereum gas oracles when building Base-specific dApps, wallets, or trading bots that require accurate L2 fee data.
Side effects
- Invalid speed enum value returns a 400 error
- Payment not completed via x402 returns a 402 Payment Required response
- Base Mainnet RPC downtime may result in stale or unavailable fee data
- Network congestion spikes may cause fee estimates to be outdated by the time the transaction is submitted
