Authorizations

ApiKeyAuthApiKeyAuth

api-key string

NOWNodes API key passed in the api-key header.

Returns balances and transactions of an address. Transactions are sorted by block height with newest blocks first. Response size is controlled by the details parameter.

At details=basic, mempool transactions are not aggregated: unconfirmedBalance, unconfirmedSending, and unconfirmedReceiving are omitted, and unconfirmedTxs reports the raw mempool index size for the address.

Load estimate: Variable; basic is low, token/tokenBalances and txids/txslight are medium, and txs can be high as it grows with pageSize, transactions, token rows, filters, and protocol enrichment.
