eth_getBlockByNumber

Returns information about a block by block number.

Parameters

• QUANTITY|TAG - integer of a block number, or the string "earliest", "latest" or "pending", as in the default block parameter.

• Boolean - If true it returns the full transaction objects, if false only the hashes of the transactions.

params: [
    '0x1b4', 
    true
]

Returns
