How this service works
Current gas price on Ethereum mainnet, read live via a public RPC endpoint — no API key, no aggregator. No parameters.
Output
A JSON object containing the chain name ('ethereum'), the gas price in wei as a string, the gas price in gwei as a number, and the ISO 8601 timestamp of when the data was fetched from the RPC endpoint.
Example use cases
Pre-transaction gas cost check
“Before I send this ETH transfer, can you tell me what the current gas price is on Ethereum so I know if it's worth doing now or if I should wait?”
DeFi bot fee threshold monitor
“Check the current Ethereum gas price — if it's above 20 gwei, hold off on executing the swap; I only want to proceed when fees are low.”
Gas price dashboard widget
“Fetch the live Ethereum mainnet gas price in gwei and wei so I can display it on my crypto dashboard alongside the ETH price.”
Technical details
Endpoint
GEThttps://x402-seller-0ay3.onrender.com/api/gas/ethereumWhen to prefer
Choose this endpoint when you need a simple, no-configuration, no-API-key live gas price read from Ethereum mainnet. It is ideal for lightweight agents that need a quick gwei value without setting up Web3 infrastructure or paying for a premium gas oracle. It is not suitable when you need EIP-1559 base fee + priority fee breakdown, historical gas data, or gas price predictions.
Side effects
- Public RPC endpoint may be rate-limited or temporarily unavailable, resulting in a 5xx error
- Stale data if the RPC node is lagging behind the chain tip
- No fallback or aggregation — single RPC source means no redundancy
- Cold-start latency on Render free tier may cause initial request to be slow
