Pay for Claude Opus 5
with crypto.
Use Claude Opus 5 through OpenLimits. Pay from your wallet, then connect your coding tools.
Connect your Opus 5 workflow after payment
For an OpenLimits project that requests Opus 5, use anthropic/claude-opus-5 as the public model ID. You can save that setting in your coding tool independently of how you pay for account access.
Crypto checkout gives you an invoice for the selected access period. Once settlement is verified, sign in and follow the Claude Code setup guide or Messages API documentation. The purchase belongs to your OpenLimits account, not a direct Anthropic subscription.
From your wallet to your workspace
An email, a plan, and a one-time invoice. No automatic crypto renewals.

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
Can I renew access without changing my Opus 5 project settings?
Yes. Renewing your OpenLimits plan does not require a different public model ID. Keep the OpenLimits endpoint and account key configured in your tool.
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.
