How this service works
Returns information about a block by block number. Includes block hash, timestamp, transactions, gas used, etc. Query: block (a block number, or 'latest').
Output
Returns the Ethereum node's JSON-RPC result object for the requested block, including block hash, parent hash, miner address, timestamp, gas limit, gas used, transaction array, and other standard block fields. Also includes metadata fields: ok (boolean), service name, and chain identifier.
Example use cases
Audit transactions at a specific block
“Pull up the full details of Ethereum block 18500000 for me — I need the block hash, timestamp, and the list of transactions that were included.”
Check the latest block on Ethereum
“What does the latest Ethereum block look like right now? Give me the block number, timestamp, gas used, and hash.”
Verify block timing for a historical event
“When exactly was Ethereum block 15537393 mined? I need the timestamp and gas used to cross-reference with a transaction I'm auditing.”
Technical details
Endpoint
GEThttps://ari001.tailb4ac3a.ts.net/v1/ventures/ethereum_rpc_api/eth_getblockbynumber?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need comprehensive block-level data from Ethereum mainnet — including hash, timestamp, gas, and full transaction list — for a specific block number or the latest block. Prefer this over balance or contract endpoints when the query is about block metadata rather than account or token state.
Side effects
- Block number out of range or not yet mined returns an error or null result
- Malformed block number (non-numeric, exceeds 12 digits) rejected by input schema validation
- 'latest' keyword misspelled returns a validation error
- Node unavailability or timeout returns ok: false with an error message
- Very high block numbers (future blocks) return null result
