How this service works
Chain head info: latest, safe and finalized block numbers + timestamps, finality lag, base fee, tx count, gas used (public RPC). 0.01 USDC/call on Base.
Output
Returns latest, safe, and finalized block numbers and Unix timestamps, the gap between latest and finalized (finality lag), current base fee in wei, transaction count in the latest block, and gas used — all sourced from public RPC for the requested chain.
Example use cases
Monitor Ethereum finality lag
“Check Ethereum's chain head right now — I want to see the latest vs finalized block numbers and how big the finality lag is.”
Check Base network congestion
“What's the current base fee and gas used on Base? I want to know if the network is congested before I send a transaction.”
Verify Arbitrum block progress
“Can you pull the latest and safe block numbers on Arbitrum along with their timestamps so I can see how fast blocks are being produced?”

Endpoint
GEThttps://task-radar-x402.vercel.app/api/block?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need a quick, real-time snapshot of chain head state for EVM-compatible networks without running your own node. Ideal for monitoring finality lag, checking base fee before submitting transactions, or validating block progress across Ethereum, Base, Arbitrum, Optimism, Polygon, or BSC at low cost ($0.01/call).
Side effects
- Unsupported chain name returns an error or defaults to Ethereum
- Public RPC node downtime may cause timeout or stale data
- Rate limiting from underlying public RPC endpoints
- Network congestion may cause slow response for heavily loaded chains
