Enhanced Transactions API

Complete API reference for Helius Enhanced Transactions endpoints. Parse transactions into human-readable formats including NFT sales, swaps, and transfers.

The Enhanced Transactions API is a legacy product in maintenance mode. It still works and these pages remain available, but it is not receiving new parser types or feature work. Its successor is Parsed Events, which decodes instructions through the IDL catalog and is available on all plans at 10 credits per request. You can also use getTransactionsForAddress for transaction history and backfill, and the Wallet API for human-readable wallet data.

Get Parsed Transactions

Parses and returns enhanced, human-readable versions of the given transactions.

Get Parsed Transactions By Address
