`GET /v4/data/block/time`

/v4/data/block/time

**20 credits per API call**

Get block number by time on the following blockchains:

*   Ethereum - ethereum-mainnet / ethereum-sepolia
*   Bitcoin - bitcoin-mainnet
*   Base - base-mainnet / base-sepolia
*   Arbitrum - arb-one-mainnet / arb-testnet
*   BNB (Binance) Smart Chain - bsc-mainnet / bsc-testnet
*   Polygon - polygon-mainnet
*   Optimism - optimism-mainnet / optimism-testnet
*   Berachain - berachain-mainnet
*   Unichain - unichain-mainnet / unichain-sepolia
*   Monad - monad-testnet
*   Celo - celo-mainnet / celo-testnet
*   Avalanche - avax-mainnet / avax-testnet
*   Gnosis - gno-mainnet / gno-testnet
*   zkSync - zksync-mainnet / zksync-testnet
*   Rootstock - rsk-mainnet / rsk-testnet
*   Ethereum Classic - ethereum-classic-mainnet / ethereum-classic-testnet
*   Lisk - lisk-mainnet / lisk-testnet
*   XDC - xdc-mainnet / xdc-testnet
*   Sonic - sonic-mainnet / sonic-blaze

To get started, provide a chain name and specify one of the filters listed below (combination of the filters is not allowed):

*   time
*   unix

If you pass a time or Unix timestamp that is in the future, the system will return the number for the latest block.

If you pass a time or Unix timestamp in the past (dating back to or earlier than the blockchain's genesis block), the system will return 0.
