How this service works
Real-Time EIP-1559 Gas Estimation and Fee History Oracle for Base Mainnet, payable via x402.
Output
Returns a JSON object with the network identifier ('base'), the current base fee in gwei, the suggested maxFeePerGas in gwei, and the suggested maxPriorityFeePerGas in gwei — all calibrated to the requested speed tier (slow, standard, fast, or instant).
Example use cases
Pre-flight gas check for DeFi trade
“Before I submit this swap on Base, what are the current fast-speed gas fees — base fee, max fee, and priority fee — so I can set my transaction parameters correctly?”
Cost-sensitive slow transaction batching
“I want to batch some low-urgency transactions on Base. What are the slow-speed gas fees right now so I can minimize costs?”
Real-time gas monitoring for a trading bot
“Pull the instant-speed EIP-1559 gas estimates from Base Mainnet right now — I need the suggested max fee and priority fee in gwei to feed into my trading bot.”
Technical details
Endpoint
GEThttps://baseshield-x402-ojil.vercel.app/v1/gasWhen to prefer
Use this endpoint when you need live, EIP-1559-compatible gas fee estimates specifically for Base Mainnet and want a speed-tiered recommendation (slow/standard/fast/instant) rather than computing fees from raw RPC data yourself. Prefer it over generic gas trackers when building agents or bots that transact on Base and need reliable, structured gwei values ready to plug into transaction parameters.
Side effects
- Invalid speed enum value returns an error
- x402 payment failure if USDC balance is insufficient or payment header is malformed
- Network RPC unavailability causes stale or missing fee data
- Rate limiting if payment is not properly attached
