The official Helius AI tooling repository — everything you need to interact with Helius and Solana from the command line, from AI assistants like Claude, or autonomously as an agent.

## helius-cli
A CLI built for developers and LLM agents to manage Helius accounts, query Solana blockchain data, and automate workflows.
### Installation
bash
npm install -g helius-cli
# or
pnpm add -g helius-cli
### Quick Start
#### Existing Helius users
If you already have an API key, just set it and go:
bash
helius config set-api-key
Get your key from dashboard.helius.dev. That's it — skip the steps below.
#### New users — create an account
Step 1 — Generate a keypair
bash
helius keygen
This creates a new Solana keypair and saves it to ~/.helius/keypair.json. The public key is printed to the terminal — you'll need it for the next step.
Step 2 — Fund the keypair (only for autopay)
Skip this step if you'll pay through the hosted payment link (the default). For autopay (--pay), send the following to the public key from step 1:
$10 USDC (the Agent plan, one-time)
A small amount of SOL to cover transaction fees (~0.001 SOL is sufficient)
You can use any wallet or exchange to send funds.
Step 3 — Create your Helius account
Every new account needs an email, first name and last name. The wallet is only used to pay.
bash
# Default: prints a hosted payment link; pay with any wallet, then finalize
helius signup --email you@example.com --first-name Jane --last-name Doe
helius signup --resume
# Or autopay from the funded keypair
helius signup --pay --email you@example.com --first-name Jane --last-name Doe
Step 4 — Start using the CLI
bash
# Query a wallet balance
helius balance
# Parse a transaction
helius tx parse
### Features
Account & Auth — Generate keypairs, create and upgrade Helius accounts, manage projects and API keys
Blockchain Queries — SOL and token balances, transaction parsing and history, digital assets (NFTs) via the DAS API, account info, block data, network status, and priority fee estimation
Webhooks — Create, update, and delete webhooks for transaction monitoring
Real-time Streaming — WebSocket subscriptions for accounts, logs, slots, signatures, and programs
Staking — Create and manage stake accounts, stake and unstake transactions
ZK Compression — 24+ commands for working with compressed accounts and tokens
Transaction Sending — Use Helius Sender for low-latency sends
### Configuration
The CLI stores configuration at ~/.helius/config.json. API keys are resolved in this order:
1. --api-key flag
2. HELIUSAPIKEY environment variable
