Anthropic bans Claude resale and proxy access

Anthropic has updated its Usage Policy, introducing strict new restrictions aimed at preventing abuses related to the commercial resale of access to the Claude AI models. These changes affect developers and businesses utilizing the platform globally.

The new provisions are set to take effect on November 12, targeting various unauthorized practices and third-party intermediaries attempting to monetize personal accounts.

• Anthropic banned profiting from personal accounts and reselling subscriptions through third-party proxies.
• Unauthorized acquisition of paid features using stolen data, fake payment details, and payment workarounds is prohibited.
• The policy applies to Claude.ai and Claude Code users, as well as API clients and cloud platform customers.
• Violators face warnings, rate limiting, suspension, or complete termination of service.

Key restrictions and crackdown on intermediaries

The first restriction targets shadow resellers who monetize personal accounts or establish proxy services to provide unauthorized access to Anthropic models. Developers and integrators are now barred from misrepresenting product details or end-users when embedding the technology into third-party apps.

This update significantly alters the landscape for unofficial middlemen offering discounted access outside official subscription channels. The company aims to organize its ecosystem and protect its business interests.

Payment security and preventing fraud

The second major change focuses on preventing unauthorized access to paid features. The ban covers the use of stolen credentials, fake payment details, and any other technical or organizational methods designed to bypass payment.

These measures are designed to reduce fraudulent transactions and protect the infrastructure from overloading caused by bad actors attempting to access premium features for free.

Scope of the updated platform policy

The revised policy covers a wide range of participants, from regular users of the Claude.ai web interface and Claude Code development tool to corporate clients utilizing APIs, cloud platforms, and authorized resellers.

Notably, this marks the second tightening of platform rules since September 2025, demonstrating the company's commitment to strictly controlling the usage of its technologies amidst growing popularity.

Penalties for violators and business impact

Anthropic reserves the right to take enforcement actions against violators, ranging from formal warnings and rate-limiting to the temporary or permanent suspension of service.

This means developers and businesses must strictly adhere to official integration guidelines to avoid service disruptions and account bans.
