Authorizations

ApiKeyAuthApiKeyAuth

api-key string

NOWNodes API key passed in the api-key header.

ApiKeyAuthApiKeyAuth

X-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.

Ethereum-like transactions have one vin and one vout, tokenTransfers, ethereumSpecific execution data, and optional addressAliases.

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

live-verified behavior:

Live capture: Komodo transaction (version 4, lockTime carried over from the zcash design); the normalized shape has vin with script hex and vout with addresses; size/vsize are omitted by this build. hex truncated in the example for readability.

Parameters

txidstringrequiredpath

Transaction id/hash.

spendingbooleanquery

Include spending transaction metadata for UTXO outputs when available.

Response

200OK

Normalized transaction.

400Bad Request

Public API error (JSON).

401Unauthorized

Missing or invalid API key (plain text).
