How this service works
Compare live gas prices and estimated transfer cost across major EVM chains.
Output
Returns a comparison of live gas prices and estimated transfer costs for each requested EVM chain (or all supported chains if none specified), allowing the caller to identify the cheapest or most efficient chain for a transaction.
Example use cases
Cheapest chain for token transfer
“I want to bridge some USDC — can you check live gas fees across all supported EVM chains and tell me which one is cheapest for a transfer right now?”
Multi-chain gas monitoring for DeFi bot
“Before my arbitrage bot executes, check the current gas prices on Ethereum, Arbitrum, and Optimism and give me the estimated transfer cost on each so I can pick the most cost-efficient route.”
Developer chain selection for deployment
“I'm about to deploy a smart contract — compare gas prices across all major EVM networks right now so I can decide which chain to deploy on to minimize costs.”
Technical details
Endpoint
POSThttps://gas-price-comparator.pdfextractapi.workers.dev/compareWhen to prefer
Use this endpoint when you need a simultaneous, real-time gas price comparison across multiple EVM-compatible chains in a single API call, especially when optimizing for transaction cost efficiency across Layer 1 and Layer 2 networks. Prefer this over querying individual chain RPC nodes separately when you want a normalized, aggregated view without managing multiple connections.
Side effects
- Unsupported chain key provided — endpoint may ignore or return error for unrecognized chain identifiers
- Upstream RPC node unavailability — gas data for some chains may be stale or missing
- Rate limiting or payment failure — x402 payment not processed, request rejected
- Empty chains array — behavior may vary (all chains or error)
- Network timeout — real-time price fetch from multiple chains may occasionally time out
