Ethereum Gas Price Monitor

Check current Ethereum gas prices instantly for transaction cost optimization and network monitoring. Returns safe, standard, and fast gas prices in Gwei along with the suggested base fee and latest block number — sourced from the Etherscan gas oracle API. Schedule it every few minutes on Apify to build a gas price history for alerting and analysis.

Features

• Three speed tiers — returns safe (slow), propose (standard), and fast gas prices in Gwei
• Base fee tracking — includes the suggested base fee for EIP-1559 transactions
• Block reference — reports the latest block number for precise timing context
• No API key required — uses the public Etherscan gas oracle endpoint
• Single-request execution — completes in seconds with minimal resource usage
• Pay-per-result pricing — one event per gas check, with charge-limit safety
