What it returns

The newest limit blocks one chain has produced, head first and one per height: number, hash, parent hash, time, transaction count, gas used and limit, base fee and the miner address. Gas figures and the base fee are decimal strings (the base fee in wei); "0" is a real value, as on BNB, and null means it was not published. What miner names differs by chain: the validator on BNB, the fee recipient on Ethereum (usually a block builder), a sequencer fee vault on Base, the fixed sequencer address on RHC. On the fastest chains the head moves several times a second, so two calls a second apart rarely agree on it.

Request

Send your key in the x-dex-data-key header. Replace each <placeholder> with a real value.

curl -H "x-dex-data-key: $DEXDATA_API_KEY" \
  "https://api.dexdata.io/api/external/chain-analysis/latest-blocks/BNB"

Parameters
Parameter	Description
`limit` query · integer · optional	How many blocks to return, head included: 1 to 20. Defaults to 10.
`chain` path · string · required	Ethereum, BNB, Base, Stable, Arc or RHC. SOL returns 400: no wired source publishes its newest slots with hashes and times, only a bare slot number. CELO, ARB, OP and SCROLL return 400 here.

Response fields

A JSON response. Every field is always present; null means the value could not be established, never zero.

Response fields of The newest blocks on a chain
Field	Type	Description
`blocks`	object[]	Head first, one block per height.
`blocks[].number`	integer	The block height.
`blocks[].hash`	string	The block hash.
`blocks[].parentHash`	string \| null	The hash of the block before this one, or null when not published.
`blocks[].timestamp`	integer \| null	Unix seconds the block was produced at.
`blocks[].transactionCount`	integer \| null	Transactions in the block. 0 is a real empty block, different from null.
`blocks[].gasUsed`	string \| null	Gas used by the block, as a decimal string.
`blocks[].gasLimit`	string \| null	The block gas limit, as a decimal string. RHC reports a fixed 1125899906842624 (2^50) on every block — a real value, not a limit blocks approach.
`blocks[].baseFeePerGasWei`	string \| null	Base fee per gas in wei, as a decimal string. "0" is real (BNB); null means not published.
`blocks[].miner`	string \| null	The address the block names as its miner — see the endpoint description for what it is per chain.
