How this service works
Free verified Ethereum block-header sample. Purchase any supported block selector at GET /ethereum-block?block=25750000 for $0.00295.
Output
A normalized Ethereum block header object containing fields such as block number, block hash, parent hash, timestamp, miner/validator address, gas limit, gas used, base fee per gas, difficulty, and other chain metadata for the requested block.
Example use cases
Verify block timestamp for on-chain event
“I need the block header for Ethereum block 25750000 — specifically the timestamp and hash so I can verify when an on-chain event happened.”
Gas analysis for historical block
“Pull the block header for Ethereum mainnet block 20000000 and give me the gas limit and gas used so I can analyze network congestion at that point.”
Audit block metadata for compliance
“Fetch the full normalized block header for Ethereum block 18500000, including the miner address and difficulty, for a compliance audit trail.”
Technical details
Endpoint
GEThttps://appearing-clinics-show-wrote.trycloudflare.com/ethereum-block-sampleWhen to prefer
Use this endpoint when you need structured, normalized Ethereum mainnet block header data for a specific block number or selector. Prefer this over raw RPC calls when you want a clean, pre-parsed response without managing your own Ethereum node. It is well-suited for agents needing block timestamps, gas metrics, or hash verification for a known block height.
Side effects
- Invalid or out-of-range block number returns an error or empty response
- Block selector not recognized returns a 400 bad request
- Network connectivity to Ethereum node fails resulting in a 5xx error
- Payment not completed for paid tier results in 402 Payment Required
- Rate limiting may occur under high request volume
