How this service works
Gas price now on every EVM chain ($0.001): base fee, priority fee percentiles and the USD cost of a transfer and a DEX swap on Ethereum, Base, Arbitrum, Optimism, Polygon and other chains, cheapest first. Use to budget or time a transaction.
Output
A ranked list of EVM chains (Ethereum, Base, Arbitrum, Optimism, Polygon, and others) sorted cheapest first, each showing: current base fee, priority fee percentiles, estimated USD cost of a standard transfer, and estimated USD cost of a DEX swap.
Example use cases
Timing a high-value DeFi swap
“Before I execute this swap on Ethereum, can you check current gas prices across all EVM chains and tell me which one is cheapest right now and what the swap would cost in USD?”
Picking the cheapest chain to deploy
“I need to deploy a contract and want to minimize gas costs — can you pull live gas fees across Ethereum, Arbitrum, Base, Optimism, and Polygon and tell me which is cheapest right now?”
Monitoring gas before a scheduled transfer
“Check the current gas prices on all major EVM chains and tell me the USD cost of a simple ETH transfer on each one — I want to know if now is a good time to send or if I should wait.”
Technical details
Endpoint
GEThttps://api.marketintelligenceapi.com/api/v1/markets/gas-price?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need a real-time, multi-chain gas price snapshot to budget or time an EVM transaction. It is ideal for agents that need to compare costs across chains before deciding where to execute a swap or transfer. Prefer this over chain-specific RPC calls when you need a normalized, cross-chain comparison with USD cost estimates in a single call.
Side effects
- Payment not included or insufficient — endpoint requires $0.001 USDC x402 payment header
- Upstream chain RPC unavailable — may return stale or missing data for specific chains
- Rate limiting if payment is not properly attached
- Network timeout if multiple chains are slow to respond
