How this service works
Multi-chain Gas Price
Output
Returns current gas price data for the requested blockchain networks (or all five supported chains by default), including fee estimates that can be used to compare transaction costs across chains before executing on-chain operations.
Example use cases
Cheapest chain for DeFi swap
“Before I execute my swap, check gas prices on Ethereum, Arbitrum, Optimism, and Base and tell me which one is currently cheapest.”
Gas spike alert for automation
“Fetch the current gas prices across all supported chains and let me know if any of them are spiking above normal levels right now.”
Multi-chain transaction cost planning
“I'm about to deploy a smart contract — can you pull the current gas prices on Ethereum and Polygon so I can estimate which one will cost less to deploy on?”
Technical details
Endpoint
POSThttps://x402.agentfund.net/x402/onchain_gasWhen to prefer
Choose this endpoint when you need real-time gas price data across multiple EVM-compatible chains simultaneously in a single API call. It is particularly useful for DeFi automation agents, wallet applications, or transaction routers that need to compare fees before deciding which network to use. Prefer this over chain-specific RPC calls when you need a unified multi-chain view without managing multiple provider connections.
Side effects
- Invalid chain name in the chains array returns an error or omits that chain
- Network connectivity issues to on-chain RPC providers may return stale or missing data
- Empty chains array may return all chains or an error depending on implementation
- Rate limiting if called excessively without proper x402 payment headers
