How this service works
What a typical operation costs right now in USD on 12 EVM chains (Ethereum, Base, Arbitrum, Optimism, Polygon, BNB, Avalanche, Gnosis, Linea, Scroll, Sonic, Unichain): native transfer, ERC-20 transfer, DEX swap or NFT mint, sorted cheapest first.
Output
A JSON object containing a list of EVM networks each with: chain name, estimated gas units, gas price in gwei, native token price in USD, and total operation cost in USD. Also includes the name of the cheapest chain, the operation type queried, and the data source used.
Example use cases
Cheapest chain for token bridging
“I need to send some ERC-20 tokens and want to pay as little gas as possible — which of the 12 EVM chains is cheapest for an ERC-20 transfer right now, and what's the USD cost on each?”
Comparing DEX swap costs before trading
“Before I execute a swap on a DEX, can you tell me what a swap would cost in USD on Ethereum, Arbitrum, Base, and Optimism right now so I can pick the cheapest one?”
NFT mint cost across chains
“I'm about to mint an NFT and want to know which chain will cost me the least — can you check the current USD cost of an NFT mint across all the supported EVM networks and tell me which is cheapest?”

Endpoint
POSThttps://api.vextorium.com/coste-operacion-pago?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a real-time, multi-chain USD cost comparison for a specific on-chain operation (native transfer, ERC-20 transfer, DEX swap, NFT mint) across 12 popular EVM networks simultaneously. Prefer it over single-chain gas APIs when the goal is to find the cheapest chain for a given operation type, or when building cost-aware routing logic for multi-chain applications.
Side effects
- Missing or invalid 'operacion' enum value causes schema validation error
- Upstream gas oracle unavailability may result in null cost values for some chains
- Network congestion may cause stale or delayed gas price data
- Unsupported operation type returns an error or empty response
