Technical details
Endpoint
POSThttps://stablecrypto.dev/api/etherscan/gas/gasestimateWhen to prefer
Use this endpoint when you need to estimate how long a transaction will take to confirm on an EVM chain at a specific gas price in wei. Ideal for pre-flight checks before submitting transactions, helping users decide whether to increase gas for faster inclusion. Best suited for Ethereum mainnet and other Etherscan-supported chains.
Side effects
- Invalid chain ID returns an error or unsupported chain message
- Gas price of 0 or negative value may return an error
- Etherscan API downtime may cause timeout or 5xx error
- Extremely low gas prices may return no estimate or indefinite confirmation time
- Malformed request body returns 400 validation error
