What is Parsed Events?

Parsed Events returns parsed Solana transaction data from raw transaction signatures or address history. It returns the same parsed transaction model that Parsed Streams delivers, as REST JSON. Instructions are decoded through the same IDL catalog that powers Parsed Streams: named instruction arguments, named accounts, and inner (CPI) instructions. Parsed Streams pushes matching transactions to you in real time over WebSocket; Parsed Events parses signatures and address history on demand. If the decoding model is new to you, read the Parsed Streams mental model first. Parsed data includes:
  • decoded instruction names, accounts, and arguments;
  • transaction and instruction summaries;
  • native SOL transfers;
  • SPL Token and Token-2022 transfers;
  • structured summary data (parsedData) for supported protocols;
  • decoded custom program errors when program metadata is available;
  • the original raw transaction payload when requested.

​
Methods

Parsed Events has two REST methods.

How it compares

vs Parsed Streams

Parsed Streams pushes decoded transactions over WebSocket as they land, filtered server-side at the instruction level. Parsed Events parses signatures and address history on demand over REST.

vs Enhanced Transactions

Enhanced Transactions is the previous-generation parse and history API built on fixed event types. Parsed Events decodes instructions through the IDL catalog into named arguments and accounts.

​
Access and pricing

Parsed Events is generally available on all plans, including Free. It replaces the legacy Enhanced Transactions API, which stays in maintenance mode. Get your API key from the Helius Dashboard and send requests to https://mainnet.helius-rpc.com. Authenticate with your project’s API key, passed as the api-key query parameter. Each request costs 10 credits. See Credits for the full price list. Credit metering starts on September 24, 2026. Projects that used Parsed Events before that date are not charged until October 1, 2026.
