Know what you are paying for

One access period

Day: 24 hours. Week: 7 days. Max and Ultimate: 30 days with crypto. Compare current plan prices and model access before purchase. The final fiat price and crypto amount appear in checkout.

Your own OpenLimits account

Payment purchases OpenLimits access. It does not fund a provider account or activate a ChatGPT or Claude website subscription. OpenLimits is an independent service.

Before you send a payment

Why might a cryptocurrency be unavailable for my plan?

Each asset and network can have a minimum payment. Checkout checks that minimum against your plan price. Choose another available currency or plan if the amount is too small.

Which cryptocurrencies can I use?

Checkout shows the currently available assets, networks, and minimum payment amounts. Check there for Bitcoin, Ethereum, USDT, USDC, or another preferred asset; availability varies. Send only the currency on the network specified by your invoice, with any required memo or tag.

Is crypto a recurring subscription?

No. Crypto purchases are one-time payments for the selected access term. There is no automatic wallet debit. Day access lasts 24 hours, Week lasts 7 days, and Max and Ultimate crypto purchases last 30 days.

When does my access start?

Access activates after the full payment has been verified. The invoice displays payment status while confirmations are processed. New users receive a sign-in link at the email supplied during registration.

Do discount codes or referral rewards apply?

Crypto checkout uses the full configured plan price. Promotional discounts and referral rewards are available with eligible Stripe purchases only.

What if I send too little or use the wrong network?

Do not make another transfer blindly. Keep the invoice and transaction details and contact support. Partial payments do not activate access until settlement is verified; sending on another network may prevent the payment from being detected.
