Helius API uses API keys to authenticate requests. Every API request must include your API key as a query string parameter (api-key=YOUR_API_KEY) to verify your identity and permissions.

​
Getting an API Key

  1. Create an account on the Helius Dashboard
  2. Navigate to the API Keys section
  3. Click Create New API Key and provide a descriptive name for your project

​
Security Best Practices

  • Never expose your API key in client-side code, public repositories, or browser-accessible areas
  • Store your API key securely using environment variables or secret management services
  • Set up IP restrictions for your API keys when available in the dashboard
  • Monitor your API usage in the Helius Dashboard to detect unusual patterns
  • Consider using different API keys for development and production environments

​
Rate Limits

API key usage is subject to rate limits based on your subscription plan. Monitor your usage in the Helius Dashboard to ensure you stay within your allocated limits.
