# Availability and payment methods

> Where the service can be used, and how to pay when card networks are unavailable.

_Source: https://aiprimetech.io/docs/resources/supported-countries/ · Home > Docs > Resources_

The API itself has no geographic restriction — it is a standard HTTPS endpoint reachable anywhere with internet access. What varies is payment.


## Paying

| Method | Availability | Notes |
|---|---|---|
| Bank card | Most countries | Processed by our payment provider; some issuers decline cross-border AI purchases |
| Crypto (USDT, BTC, ETH) | Everywhere | The reliable route where card payments are blocked, and it carries the credit bonus |

Crypto is the common path for users whose region cannot complete card checkout with the upstream providers directly. Current bonus rates are on [Pricing](/docs/billing/pricing/).


## If a card is declined

1. Check the issuer did not block it as an international or high-risk merchant transaction.
2. Try a different card, or switch to crypto.
3. Contact [support@claudeapikey.dev](mailto:support@claudeapikey.dev) with the approximate time of the attempt — never send full card details.

> You are responsible for complying with the laws applicable to you, and with the acceptable-use policies of the underlying model providers.
