The leading Solana RPC and infrastructure platform. Fast, reliable APIs for building on Solana.

## Getting Started

1. Sign up at https://dashboard.helius.dev
2. Get your API key
3. Start building with any of our APIs below

## Getting Started (Agents)

Programmatically create a Helius account and generate an API key.

### Step 4: Signup and Get API Key

```bash
helius signup --json
```

#### Success Response (exit code 0):

```json
{
  "status": "SUCCESS",
  "wallet": "YourWalletAddress...",
  "projectId": "project-uuid",
  "projectName": "Project Name",

https://www.helius.dev/docs/api-reference/zk-compression/llms.txt

### Deprecated APIs

| Deprecated | Use Instead | Reason |
|------------------|-------------|--------|
| `mintCompressedNft` | Use Metaplex Bubblegum SDK directly | Helius mint API is deprecated |
| `queryMetadataV1` | `getAsset` or `searchAssets` (DAS API) | Token Metadata API is deprecated |

## Common Use Cases

| I'm building... | Use these Helius products |
|-----------------|---------------------------|
| Trading bot | Helius Sender (fast tx submission) + Priority Fee API + LaserStream (real-time prices) |
| Wallet app | DAS API (getAssetsByOwner) + getTransactionsForAddress (complete history with token accounts) or Wallet API for REST endpoints|
| NFT marketplace | DAS API (searchAssets, getAssetsByGroup) + Webhooks (track sales/listings) |
| Token launcher | Helius Sender + Priority Fee API + Webhooks (monitor new token) |
| Analytics dashboard** | Enhanced Transactions API + getTransactionsForAddress (historical data) |
| DeFi protocol | LaserStream (real-time account updates) + Helius Sender + Priority Fee API |
| Sniper/MEV bot | LaserStream gRPC (lowest latency) + Helius Sender (staked connections) |
| Portfolio tracker | DAS API (getAssetsByOwner with showFungible) + Enhanced Transactions |
| Airdrop tool | AirShip (95% cheaper with ZK compression) |
| Jupiter/swap integration | Helius RPC + Helius Sender for transaction submission |

## Which API should I use?

| Need | API |
|------|-----|
| Get wallet NFTs and tokens | DAS API |
| Parse transaction history | Enhanced Transactions |
| Real-time event notifications (HTTP) | Webhooks |
| Real-time streaming (WebSocket) | WebSockets |
| Lowest latency streaming | LaserStream gRPC |
| Standard Solana RPC calls | RPC |
| Estimate priority fees | Priority Fee API |
| Work with compressed accounts | ZK Compression |
| Simple REST endpoints for querying Solana wallet data | Wallet API |

## Don't Confuse These

| If you want to... | Use this | NOT this | Why |
|-------------------|----------|----------|-----|
| Get wallet's NFTs and tokens | `getAssetsByOwner` (DAS API) | `getTokenAccountsByOwner` | `getTokenAccountsByOwner` returns raw accounts, not token metadata |
| Get complete transaction history | `getTransactionsForAddress` | `getSignaturesForAddress` | `getTransactionsForAddress` includes token accounts and `getSignaturesForAddress` does not |
| Get transaction history for cNFTs | `getSignaturesForAsset` (DAS API) | `getSignaturesForAddress` | `getSignaturesForAddress` doesn't work for compressed NFTs |
| Stream real-time data (new projects) | LaserStream gRPC | Yellowstone gRPC on dedicated nodes | LaserStream is simpler, provides 24-hour replay, supports auto-reconnects | 
| Send transactions reliably | Helius Sender (dual routes to validators + Jito) | Standard `sendTransaction` | sendTransaction uses a single path and has lower landing rates |
| Get priority fee estimates | `getPriorityFeeEstimate` | `getRecentPrioritizationFees` | `getRecentPrioritizationFees` requires manual calculation |
| Search NFTs by collection | DAS API `getAssetsByGroup` or `searchAssets` | `getProgramAccounts` | `getProgramAccounts` is expensive, slow, and data could be unindexed |
| Get real-time data | Enhanced WebSockets or LaserStream gRPC | Polling for real-time data | Polling is inefficient, higher latency, uses credits |

## Key Concepts

| Term | Definition |
|------|------------|
| DAS (Digital Asset Standard) | Standardized API for querying NFTs, tokens, and compressed assets with a unified interface |
| cNFT (Compressed NFT) | NFTs stored in merkle trees instead of individual accounts; 1000x cheaper to mint |
| ZK Compression | Technology to reduce on-chain storage costs by 98% using zero-knowledge proofs |
| Helius Sender | Ultra low latency transaction submission service routing through staked connections (via Solana's largest validator) and Jito simultaneously |
| LaserStream | Helius's managed gRPC streaming service with historical replay and auto-reconnection |
| Yellowstone gRPC | Open-source Solana Geyser plugin for streaming; available on Helius dedicated nodes |
| Priority Fee | Additional fee (in microlamports) to prioritize transaction inclusion in blocks |
| Staked Connections | Direct connections to validators through stake-weighted routing for faster and more reliable transaction landing |
| Associated Token Account (ATA) | The standard token account address derived from a wallet + mint; holds tokens on behalf of wallet |
| Commitment Level | Transaction finality: `processed` (fastest, may revert), `confirmed` (basically final), `finalized` (guaranteed) |
