> Arc API method that returns information about a transaction by block number and transaction index position. Arc via Chainstack.

Arc API method that returns information about a transaction by block number and transaction index position.

## Parameters

* `blockNumber` — the block number (hex) or tag (`latest`, `earliest`, `pending`)
* `transactionIndex` — the transaction index position (hex)

## Response

* `result` — the transaction object, or `null` if not found:
  * `hash` — transaction hash
  * `nonce` — sender's transaction count
  * `blockHash` — hash of the containing block
  * `blockNumber` — block number
  * `transactionIndex` — index in the block
  * `from` — sender address
  * `to` — recipient address (null for contract creation)
  * `value` — value transferred in wei
  * `gas` — gas limit
  * `gasPrice` — gas price
  * `input` — transaction data
  * `v`, `r`, `s` — signature values
