If you’re trying to use Amazon Bedrock and encounter issues with activating an Anthropic Claude model, here’s a simple solution to help you understand and resolve the problem.
When you activate the Anthropic Claude model in Amazon Bedrock for the first time, the system automatically starts a subscription through the AWS Marketplace. This process creates a subscription under your account automatically. However, for this to happen smoothly, the IAM role that you’re using to make the request must have specific permissions—namely, aws-marketplace:ViewSubscriptions and aws-marketplace:Subscribe.
If you see an error message saying “INVALID_PAYMENT_INSTRUMENT,” it probably means the subscription process is failing because of a payment validation problem. This issue goes beyond permissions and is often related to how payments are handled in your account, especially if you are using an AWS account with special arrangements like AISPL or have AWS Activate credits.
Currently, there’s limited public information about whether AISPL accounts have restrictions when subscribing to Anthropic models or if AWS Activate credits automatically cover usage costs for these models. It’s also unclear whether alternative billing options are available for these accounts.
Since you’ve already reached out for support, the best next step is to continue working with AWS Support. They can look into your specific account details and help identify why the payment validation is failing. They can also tell you if there are any special steps or account setups needed to use Anthropic models with your account type.
When communicating with support, make sure to include all relevant details, such as the specific error message you’re seeing and that your account is an AISPL one with AWS Activate credits. Providing this information will help them troubleshoot more effectively.
In summary, your best approach is to contact support directly, provide detailed information, and ask them to assist with resolving the payment validation issue for your account. They can guide you on any special requirements or arrangements necessary to access Anthropic models via Amazon Bedrock successfully.
