How this service works
Latest (or specific) block header, decoded
Output
A decoded block header object containing fields such as block number, block hash, parent hash, timestamp, miner/validator address, transaction root, and other standard EVM-compatible block metadata.
Example use cases
Monitor chain head in real time
“Keep checking the latest block header for me and tell me when a new block is mined — I want to see the block number and timestamp each time.”
Verify a specific block by number
“Can you pull the decoded block header for block 20000000 so I can confirm its hash and timestamp?”
Sync blockchain state for DeFi dashboard
“Fetch the latest block header so I can display the current chain height and block time on my DeFi dashboard.”

Endpoint
GEThttps://santyvv-x402.santyvv1993.workers.dev/api/chain/block?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a quick, pay-per-call decoded block header without managing your own RPC node or API key. Ideal for lightweight agents that occasionally need chain head data or specific block metadata without committing to a full blockchain node subscription.
Side effects
- Invalid or non-existent block number returns a 404 or error response
- Network or RPC node unavailability causes a 503 timeout
- Malformed query parameters result in a 400 bad request
- Payment not processed correctly results in a 402 payment required error
