How this service works
Cheap, factual EVM chain lookups priced per call in USDC. Base, Polygon, Arbitrum, Optimism and Ethereum.
Output
A JSON object containing the chain name, current base fee in gwei, overall gas price in gwei, and a simple transfer cost breakdown including gas units (21000), the estimated cost amount in native token, and the token symbol (e.g. ETH, MATIC).
Example use cases
Pre-transaction gas cost check
“Before I send this token transfer on Polygon, what's the current gas price and how much would a simple transfer cost me right now?”
Cheapest chain gas comparison
“I want to find the cheapest chain to transact on — can you check current gas prices on Base, Arbitrum, and Optimism so I can compare?”
DeFi bot fee monitoring
“Check the current EIP-1559 base fee and priority tiers on Ethereum mainnet so I can decide if it's worth executing my trade now or wait for lower fees.”
Technical details
Endpoint
GEThttps://multichain-rpc.clankerceo.workers.dev/gasWhen to prefer
Choose this endpoint when you need real-time EIP-1559 gas data across multiple EVM-compatible chains (Base, Polygon, Arbitrum, Optimism, Ethereum) in a single lightweight call, especially when you want both the fee tiers and a human-readable transfer cost estimate in one response. Prefer it over raw RPC calls when you want pre-parsed gwei values without decoding hex or handling RPC provider authentication.
Side effects
- Unsupported or misspelled chain name returns an error or empty result
- RPC node temporarily unavailable causes stale or missing data
- Network congestion may cause slight lag in base fee accuracy
- Missing chain query parameter may default to a specific chain or return an error
