​
Purchasing Plans

The free plan includes limited credits and request rates suitable for development and testing. For production applications, consider a paid plan for higher limits, staked connections, and enhanced APIs. See our pricing page for detailed comparisons.
We accept both traditional payment methods (credit cards) and cryptocurrency (USDC on Solana). You can set up payment during plan selection or change payment methods in your billing dashboard.
Updates may take up to an hour. If nothing changes after that, please reach out to Support.
If payment fails, you’ll receive notifications and have a grace period to update your payment method. Your service may be temporarily downgraded to free tier limits until payment is resolved. Update payment details in your billing dashboard.

​
Paying with Crypto

Contact Support and we’ll help you transition.
• Helius pulls the required USDC from your Solana wallet at the start of each billing cycle.• The charge succeeds only if your wallet holds enough USDC.• You can revoke the authorization any time in your wallet or in Billing → Manage Authorization Limit.
Manual payments aren’t supported. You can, however, revoke the authorization right after each charge by setting the limit to 0 under Manage Authorization Limit.

​
Downgrades

You can downgrade your plan from the billing dashboard.
Crypto downgrades happen immediately. You’ll receive a prorated credit as a discount on your next subscription billing cycle for the unused portion of your current plan.
You can cancel your subscription from the billing dashboard. Your service will continue until the end of your current billing period, then revert to free tier limits.

​
Autscaling

Enable autoscaling in your project settings under the autoscaling section. This automatically purchases additional credits when you exceed your plan limits. See our autoscaling guide for details.
Autoscaling purchases additional credits when you exceed your plan limits, which appear as overages on your invoice. This is expected behavior - autoscaling prevents service interruption by automatically buying the credits you need.

​
Overages

If you exceed your credit limit, you can enable autoscaling or purchase additional prepaid credits. Learn more on the Additional Credits page.
Check for active webhooks, automated scripts, or background processes that might be making API calls. Review your usage dashboard to identify the source of credit consumption.
Your API key may have been compromised, or a webhook might be running in the background. To resolve this:
  1. Delete the current API key and create a new one.
  2. Check your webhooks from the dashboard and disable any that shouldn’t be active.
  3. If the issue persists, contact support for assistance.
To help prevent key leaks in the future, consider setting up a proxy as described in this guide.

​
Refunds

We’re unable to offer refunds on automated subscription renewals if you’ve already used the service. This follows the standard practice on most platforms.
