What it returns

The newest calls contracts made on one chain — call, delegatecall, staticcall, callcode, create, create2 and selfdestruct — with no wallet, token or transaction in the question. Most recent first: by block, then transaction index, then the call's index, all descending. A single page of the newest 50, no pagination: to walk further back, read block-internal-transactions block by block. Reverted calls are listed, with success false. RHC, ETH, OP and SCROLL.

Parameters
Parameter	Description
`chain` path · string · required	RHC, ETH, OP or SCROLL; every other chain returns 400, because no wired source publishes a chain-wide feed of internal calls for it.

Response fields

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

Response fields of Newest internal calls on a chain
Field	Type	Description
`internalTransactions`	object[]	Newest first by (block, transaction index, index).
`internalTransactions[].transactionHash`	string	The transaction that made the call, lowercase.
`internalTransactions[].blockNumber`	integer	The block the transaction was mined in.
`internalTransactions[].transactionIndex`	integer	The transaction's position in its block, from 0.
`internalTransactions[].index`	integer	The call's position among its transaction's internal calls, from 1 in execution order.
`internalTransactions[].type`	string	The EVM call kind. delegatecall, staticcall and callcode are reported as types of their own, not as a plain call.
`internalTransactions[].from`	string	The contract that made the call, lowercase.
`internalTransactions[].to`	string \| null	The callee, lowercase. null on a create or create2, whose address is createdContract.
`internalTransactions[].createdContract`	string \| null	The contract a create or create2 made, lowercase. null on every other type.
`internalTransactions[].valueWei`	string	Native coin sent with the call, in wei, as a decimal string. "0" is a real zero.
`internalTransactions[].gasLimit`	string	Gas the call was given, as a decimal string.
`internalTransactions[].success`	boolean	false when the call reverted: its value did not move and its effects were undone.
`internalTransactions[].error`	string \| null	Why the call reverted, when that is known (e.g. "execution reverted", "Parent reverted").
`internalTransactions[].timestamp`	integer	Unix SECONDS of the block.
