Get a transaction by hash

POST

https://vinu.nownodes.io/

Authorizations

ApiKeyAuthApiKeyAuth

api-key string

NOWNodes API key passed in the api-key header.

Returns the transaction with the given hash, or null if the node does not know it.

Changed in the 29 August 2026 network upgrade.

authorizationList is returned on EIP-7702 set-code transactions (type: "0x4"), supported since the 29 August 2026 upgrade.
feeRefund is now omitted when the node has no refund value for the transaction - most visibly on transactions still in the pool, where "0x0" used to be returned. Treat a missing feeRefund as unknown, not as zero.
