# Get a normalized transaction.

`GET /api/v2/tx/{txid}`

Returns normalized transaction data with the same general structure for
all supported coins. Coin-specific fields that do not fit the common
shape are omitted here; use getTransactionSpecific for backend-native
JSON.

Bitcoin-like confirmed transactions include blockHash, confirmations,
blockTime, size/vsize, value/valueIn, fees, and hex. Unconfirmed
transactions can include confirmationETABlocks and
confirmationETASeconds.

Ethereum-like transactions have one vin and one vout, tokenTransfers,
ethereumSpecific execution data, and optional addressAliases. Parsed
input data is included when the 4byte signature can be resolved.

For mined transactions, blockTime is the block timestamp. For mempool
transactions, blockTime is when this Blockbook instance first learned
about the transaction and can differ between instances.

Load estimate: Medium; grows with inputs, outputs, token transfers,
address aliases, and spending=true extra lookups.
