How this service works
Current gas price on Base (Ethereum L2), read live via a public RPC endpoint — no API key, no aggregator. No parameters.
Output
A JSON object containing the chain identifier ('base'), a UTC timestamp of when the data was fetched (fetched_at), the current gas price in wei (gas_price_wei as a string), and the gas price in gwei (gas_price_gwei as a float). No parameters required.
Example use cases
DApp transaction cost check
“Before I submit this transaction on Base, what's the current gas price so I know if it's a good time to send it?”
Gas fee monitoring for automated bot
“Check the live gas price on Base right now and tell me if it's below 0.01 gwei so my trading bot knows whether to proceed.”
Cost estimation for smart contract deployment
“I'm about to deploy a contract on Base — what's the current gas price in gwei so I can estimate my deployment cost?”
Technical details
Endpoint
GEThttps://x402-seller-0ay3.onrender.com/api/gas/baseWhen to prefer
Choose this endpoint when you need a quick, free-of-friction gas price check on Base with no API key setup — ideal for agents that need live Base gas data in a simple GET call. Prefer it over manual RPC calls when you want a pre-parsed gwei + wei response with a timestamp. Not suitable if you need gas price history, gas estimates for specific transaction types, or multi-chain comparisons in a single call.
Side effects
- Public RPC endpoint may be temporarily unavailable or rate-limited, resulting in a 5xx error
- Stale data if the RPC call times out and a cached value is returned
- Render.com cold-start latency if the service has been idle, causing a slow first response
- Network congestion on Base may cause brief RPC failures
