How this service works
Live gas prices across Base, Ethereum, Arbitrum, and Optimism, plus ETH price, block number, gas prediction, and large Base whale transfers. Paid via x402 on Base mainnet.
Output
A JSON object containing the current Ethereum block number (integer) and a Unix timestamp indicating when the data was retrieved.
Example use cases
Transaction finality check
“Can you grab the current Ethereum block number so I can verify whether my transaction from block 20,800,000 has enough confirmations?”
Smart contract deployment timing
“I'm about to deploy a smart contract — what block is Ethereum on right now so I can log it as my deployment reference block?”
On-chain event monitoring
“Keep checking the current Ethereum block number every few seconds and let me know when we've passed block 21,000,000.”
Technical details
Endpoint
GEThttps://gas-optical-production-30aa.up.railway.app/block-number?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need a live, real-time Ethereum block number with minimal latency and are willing to pay a $0.0001 USDC micropayment per call. Prefer this over free public RPC endpoints when you need reliable uptime and the x402 payment model fits your workflow. It is ideal for agents that need block numbers for timing, finality checks, or on-chain event correlation.
Side effects
- Payment not included or invalid x402 payment header — returns 402 Payment Required
- Upstream node unavailable — returns 503 or timeout
- Network congestion causing stale block data
- Invalid or malformed request — returns 400
