How can I pay for an AI API like Claude or GPT with crypto and no credit card?

Last updated October 26, 2026 by the APIClaw team

APIClaw takes cryptocurrency through NOWPayments, so you can buy a Claude or GPT API plan with no credit card. Pick a plan from $19 to $129 a month in the dashboard, pay in a supported coin, and the plan activates once the payment is confirmed. A 50-request free trial comes first.

Why people look for an AI API without a card

Most AI APIs assume you have a credit or debit card in your name, issued in a country the vendor supports. That leaves out a lot of capable developers: people whose banks decline AI-related charges, people without access to international cards, students, freelancers who keep project spending separate, and anyone who simply prefers not to put a card on file with another service. For them, "AI API no credit card" is a practical requirement, not a preference.

APIClaw is built around crypto payment for that reason. You can get a key that works with Claude, GPT, Gemini, DeepSeek, Qwen, Kimi, GLM and other models, and pay for it without a card at any point.

How the checkout works

Payments run through NOWPayments, a third-party crypto payment processor. The flow at a high level looks like this:

The checkout shows the supported currencies, and that list is the source of truth, so look there rather than relying on a list written on a web page. The same applies to network fees and confirmation times: they depend on the currency you choose and the state of the network, so APIClaw does not quote them here. If a payment seems stuck or you paid the wrong amount, contact Telegram support with your payment details.

Try it first, with no payment at all

You do not need to pay to find out whether the service fits your workflow. The free trial gives you 50 requests, no card and no crypto, across the available models. That is enough to run a Claude Code session, a few Cursor agent tasks or a handful of API calls and see how the requests, the weights and the response speed feel. Only buy a plan once the trial has shown that the setup works for you.

What you get after paying

Plans are priced in USD per month with a daily request quota. Cycles run for 30 days and you can cancel at any time.

For more than 8,000 requests a day, ask for a custom plan through Telegram support. The quota resets every day at 00:00 UTC. There is no per-token billing, no 5-hour window and no weekly cap, and no limit on tokens per request beyond the model's own limit. Heavier models count as more than one request: Claude Sonnet counts as 2, and Claude Opus and GPT-6 Sol count as 3. The model hub shows the current weights.

Using Claude with crypto

The question "can I pay for the Claude API with crypto" has a simple answer on APIClaw: yes, and you get an Anthropic Messages endpoint as well as an OpenAI-compatible one. Claude Code uses the base URL https://apiclaw.biz (no /v1) and your APIClaw key:

export ANTHROPIC_BASE_URL="https://apiclaw.biz"
export ANTHROPIC_AUTH_TOKEN="YOUR_APICLAW_KEY"
claude

The Claude Code setup guide lists the model IDs, such as claude-sonnet-5-5 and claude-opus-5-5. Cursor agent mode uses https://apiclaw.biz/cursor, with model IDs prefixed by apiclaw/, covered in the Cursor guide. Any OpenAI-compatible client uses https://apiclaw.biz/v1.

APIClaw is independent. It is not affiliated with Anthropic, OpenAI, Google or Cursor, and it routes requests to models available through publicly available sources and provider APIs.

What to know before you pay in crypto

Crypto payments behave differently from card payments, and a few habits help. Send the exact amount the checkout shows, since an underpayment can delay activation. Do not close the checkout page before you have copied the payment details. Keep your transaction reference until the plan shows as active. And remember that crypto payments are generally not reversible the way a card chargeback is, so use the free trial to confirm the service works before you buy a plan.

Privacy and practical notes

Paying in crypto avoids handing a card number to yet another service, but it is not the same as anonymity. You still sign up with an account, your requests are tied to your key, and the payment processor sees the payment. Treat your API key like a password, rotate it if it leaks, and do not paste it into public repositories or shared screenshots.

Budgeting is simple because the price is fixed. Plans are quoted in US dollars per month, so you know the cost of a cycle before you pay, and you can cancel any time before the next 30-day cycle. There is no per-token meter running in the background, so a long agent session cannot produce a surprise invoice. The exchange rate between your coin and the dollar price is handled at the checkout, which shows the amount due for that order.

Is it worth it compared with paying per token?

Paying with a card on a per-token API is the right choice when your volume is low. If you make only a few dozen modest calls a day, per-token billing is often cheaper than $19 a month. A flat plan starts to make sense when you run long coding-agent sessions every day, because the tokens per request do not change the price. The comparison page lays out APIClaw next to OpenRouter, direct APIs and Claude Pro and Max, and the Claude Max alternative page covers the subscription angle in more detail.

Next steps

Start with the free trial, then follow the docs to connect your tool. When you are ready to pay, open the plans in your dashboard and complete the NOWPayments checkout. If you also want to see how the flat price is built, the flat-rate OpenAI-compatible API page explains it.
