Leverage the full power of Solana
Our powerful APIs, webhooks, and RPCs save you the headache of dealing with cryptic on-chain data & expensive indexers, so you can focus on your product.
Built for Developers
Helius was built to make your life easier. No need to worry parsing on-chain data, spinning up your own RPC nodes, or staying up-to-date with program changes anymore.
Webhooks
Build event-driven systems and on-chain automation. Watch for on-chain events and trigger our built-in actions (PagerDuty, smart-contracts, custom endpoints).
import axios from "axios";
const apiURL = "https://api.helius.xyz/v0/webhooks?api-key=<your-key>";
axios.post(apiURL, {
transactionTypes: ["TOKEN_TRANSFER", "DEFI_SWAP", "NFT_SALE"],
accountAddresses: ["<any_solana_address>"],
webhookURL: "my-server.com/my-endpoint"
});
Websockets
Subscribe to account changes or new transaction events for your favorite Solana accounts. No more polling. Built for ultra-low latency.
{
"events" : {
"type" : "NFT_SALE",
"amount" : "230000000",
"buyer" : "<some_solana_address>"
}
}
We provide the most powerful Solana RPC hardware around. We offer the fastest speeds at the lowest prices possible. We also provide private RPCs for serious users.
Stream on-chain events on up to 100k addresses for free.
NFT API
Quickly build bots, analytics, marketplaces, portfolio or wallet trackers using our extensive REST API and webhooks.
Write 90% less code using our services.
We decode cryptic on-chain transactions and reverse-engineer all programs and annotate them for you.
We allow you to query historical data by multiple dimensions including transaction types (DAO votes, NFT Mints, DeFi Swaps, etc) or underlying protocols (Jupiter, Magic Eden, etc).
