Get a normalized transaction.

GET

Authorizations

ApiKeyAuthApiKeyAuth

api-key string

NOWNodes API key passed in the api-key header.

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.

Parameters

txidstringrequiredpath

Transaction id/hash.

spendingbooleanquery

Include spending transaction metadata for UTXO outputs when available.

Response
