What it returns

The native-coin transfers one transaction made through internal calls — a contract paying out, forwarding or refunding coin, creating a contract with a balance, or self-destructing — in execution order, each with whether it went through. Only calls that moved value are listed; calls that moved nothing are not. The same amount to the same address can appear twice: those are two separate calls. transaction is null when the chain does not know the hash (never sent, or not mined yet), and internalTransfers is null with it. For a transaction mined in the last 15 minutes with no transfers found, internalTransfers is null too, because the list may not be complete yet; an empty list [] means there were none.

Request

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

Parameters
Parameter	Description
`chain` path · string · required	Ethereum, BNB, Base, Stable or RHC; every other chain returns 400.
`hash` path · string · required	The transaction hash: 0x followed by 64 hexadecimal characters. Not a Solana signature (base58) — Solana is not served by this resource.

Response fields

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

Response fields of Native coin moved inside a transaction
Field	Type	Description
`hash`	string	The transaction hash, lowercase.
`transaction`	object \| null	The transaction, or `null` when the chain does not know the hash.
`transaction.blockNumber`	integer	The block it was mined in.
`transaction.timestamp`	integer	Unix seconds of that block.
`transaction.status`	string \| null	Whether the transaction itself succeeded. A failed transaction moves nothing, whatever its calls report. `null` when the chain records no status.
`internalTransfers`	object[] \| null	In execution order. `[]` when the transaction moved no coin through internal calls; `null` when it is unknown or too recent to tell.
`internalTransfers[].from`	string	The contract that made the call.
`internalTransfers[].to`	string	The recipient; on a create, the contract the call created.
`internalTransfers[].valueWei`	string	Native coin moved, in wei, as a decimal string. Never zero.
`internalTransfers[].type`	string	How the value moved: a call, a contract creation, or a self-destruct paying out its balance.
`internalTransfers[].success`	boolean	`false` when the call reverted — the value then did NOT move.
`internalTransfers[].error`	string \| null	Why the call reverted, when known, e.g. `"Reverted"`. `null` on success and when no reason is known.
