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.
Your plan activates once your payment is confirmed (for crypto, once the transaction is confirmed on-chain). If it doesn’t appear shortly after, reach out to our support team.
Payment is due when the invoice is issued. If a card charge fails, you get an email with a link to pay or update your card, and a reminder 24 hours before suspension. If the invoice is still unpaid after 3 days, your project is suspended until it’s paid; once your open invoices are paid, service is restored within seconds. After 14 days unpaid, the subscription is cancelled and the project moves to the Free plan. See Unpaid Invoices for the full timeline.
Raw shreds are sold as seats in your Helius dashboard. These seats are separate from your plan’s monthly credits.To subscribe to raw shreds, open the Shreds tab in your dashboard, click + Add Seat, choose a payment method, and enter your server’s IP address.Each seat is $1,000 USD/month per IP on all plans ($800 USD/month per IP on Pro plans).Raw shreds do not consume credits. See our plans and pricing and How to Subscribe to Raw Shreds for full details.
You can remove a seat or change the IP bound to a seat self-serve from the Shreds tab in your Helius Dashboard.Seat removals are not refunded. The seat remains billed through the end of the current billing cycle, then is not renewed.Changing the IP address issues a new token for that seat. Use it to activate the new feed. The old feed is then canceled.

​
Paying with Crypto

When a payment is due, you’ll receive a payment link by email and in your dashboard. Open the link, connect your wallet or scan the QR code, and complete the payment in USDC. Once the transaction is confirmed on-chain, your payment is applied and your subscription continues.
All crypto payments are made in USDC on Solana.
You can change your payment method yourself on your Billing page. If you run into any issues, reach out to our support team.

Credits

If you have consumed all of your credits, you won’t be able to make new API requests until you have added more credits to your account through autoscaling or prepaid credits. Otherwise, a request will result in a 429 max usage reached error.
The method depends on your payment type:
  • Fiat payments: Credits are purchased through autoscaling, which automatically adds credits as needed, up to a cap
  • Crypto payments: You’ll need to purchase prepaid credits manually
Autoscaling is a credit management system that automatically purchases additional credits when you have used up your monthly allocation. This happens on-demand, meaning that credits are only purchased if they are needed to complete your requests. This ensures that your application continues running without interruption. Autoscaling is only available to fiat users. If you pay with crypto, you must purchase prepaid credits. See our autoscaling guide or guide on buying prepaid credits for details.
Enable autoscaling on your Usage page: open the Autoscaling spend card and click Enable. Autoscaling is only available to fiat users.
Autoscaling purchases additional credits when you exceed your plan’s limits, which appear as autoscaling charges on your invoice. This is expected behavior — autoscaling prevents service interruption by automatically buying the credits you need.Autoscaling charges may be billed at any time during your billing cycle, not only at the end. Amounts billed during the cycle are deducted from the end-of-cycle bill, so you’re never charged twice for the same usage. See when you’re billed for details.
Unlike autoscaling, prepaid credits are credits you purchase in advance of their usage. You manually purchase a specific amount whenever you need to add credits to your account. This is only available to crypto users. Read this guide on prepaid credits for more details.
Go to your Usage page and click Add credits on the Prepaid credits card. Choose the amount you want to buy and complete the purchase in USDC. Prepaid credits are only available to crypto users. If you pay with fiat, please set up autoscaling.

​
Unexpected Usage

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.
