How this service works
Live gas prices on Ethereum, Base, Arbitrum, Optimism and Polygon: gas price, next base fee, slow/normal/fast priority tips, and USD cost of a simple transfer.
Output
Returns a structured object per requested chain containing: current gas price (gwei), predicted next base fee, slow/normal/fast priority fee tips, and estimated USD cost of a standard ETH transfer, all reflecting real-time network conditions.
Example use cases
Pre-transaction gas check
“Before I send this ETH transfer, what's the current gas price on Ethereum and how much will the transaction cost me in USD at normal speed?”
Cheapest chain routing
“I need to do a token transfer — can you check live gas prices on Ethereum, Arbitrum, Optimism, Base, and Polygon and tell me which chain is cheapest right now?”
Gas spike monitoring
“Check the current gas fees on Ethereum and Polygon and let me know if either is unusually high — I want to know the next base fee and fast priority tip for both.”
Technical details
Endpoint
GEThttps://agents.citiviewgroup.com/v1/gas?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need real-time, multi-chain gas fee data across the five major EVM networks (Ethereum, Base, Arbitrum, Optimism, Polygon) in a single call, including USD cost estimates for simple transfers. Prefer it over chain-specific RPC calls when you need a unified, normalized response across chains without managing multiple provider connections.
Side effects
- Invalid chain name in 'chains' query param returns an error or omits that chain
- Upstream RPC node lag may cause slightly stale data during network congestion
- Payment failure via x402 protocol blocks the request before data is returned
- Empty or malformed 'chains' parameter may default to all five chains or return a 400 error
