eth_getBlockByNumber

POST
Returns block information for the specified block number.

🚧 Response taking too long? Response time may increase when including transactions!

When requesting full block information, response time can increase if the block contains many transactions.

For faster responses, exclude transactions and request only the block header (include transactions=false).

param[0]
blockNumberOrTagstringrequired
Use one of block number or block tag to specify a block.
  • Block number: hex string (ex. "0x1")
  • Block tag: enum string (ex. "latest", "earliest", "pending")
    • earliest: The oldest available block on the chain.
    • finalized: A recently finalized block that can no longer be changed. Primarily used in proof-of-stake (PoS) blockchains.
    • safe: A recent block considered safe by the network (immune to reorgs).
    • latest: The most recent block on the chain (may be subject to reorgs).
    • pending: The next block to be mined, including pending transactions in the mempool.
param[1]
