• Important reminder: Anthropic API use compliance guidance

Recently, a number of developers have reported abnormal restrictions or bans on Claude API accounts. After studying the Anthropic official service terms, we found that the following acts could trigger platform wind control, resulting in restricted or permanently blocked API access.

Anthropic Specificly Prohibited Acts

1. Building competitive products

According to the Anthropic commercial service clause D.4:

Prohibited acts:Services may not be used to build competitive products or services, including training competitive AI models, or resale services (unless explicitly authorized by Anthropic).

This means:

  • No products directly competing with other AI models based on Claude API
  • Do not train your AI model with Claude output
  • API access rights may not be resold to third parties

2. Reverse engineering

Prohibited acts:No reverse engineering or reproduction of services may be performed.

These include:

  • No attempt to extract internal parameters from Claude model
  • Model structure cannot be extrapolated by extensive searching
  • Do not develop tools to circumvent restrictions

Violations of the use policy

According to the Anthropic use policy, the following are strictly prohibited:

  • Illegal activitiesFor any purpose contrary to the law
  • Harmful contentGenerating malware, fishing content, spam
  • FraudCounterfeiting others, generating false information for fraudulent purposes
  • Sensitive data: processing of protected health information (PHI) or specific personal data
  • High-risk usesFor high-risk decisions such as medical diagnosis, legal advice, financial investment

4. Abuse of API resources

  • Rate limit violation: exceeding API call frequency limit
  • Automation abuse: Massive content generated using scripts
  • Account Sharing: Share API Key to multiple users or teams
  • Area restrictions: Use of services in countries/areas not supported by Anthropic

Recommendations for compliance

1. Clear use of scenarios

  • Only Claude API for internal tool development
  • Avoid developing a common AI assistant for the public
  • Not implying competition with Anthropic in product name or publicity

2. Data use norms

  • Do not store Claude output for model training
  • Proper filtering of user input and model output
  • Compliance with data privacy regulations (GDPR, CPCA, etc.)

3. Technical realization recommendations

  • Implementation of an appropriate human resources coordination review mechanism
  • Specify content in application generated by AI
  • Establish user feedback and error reporting mechanisms
  • Periodically review API usage mode

4. Account security

  • Secure API Key, uncoded on client
  • Regular rotation API Key
  • Monitor abnormal API call mode
  • Timely reporting on account security issues

Post-sealed complaints process

If the account number is unfortunately sealed, the following steps can be tried:

  1. View Mail:Anthropic usually sends a violation note
  2. Review of use: Check for irregularities against the use policy

    3. Submission of complaints: complaint submitted through official support channels indicating the use of the scene

  3. Provision of evidence: preparation of materials such as logs, business notes, etc.
  4. Pending review: usually 3-7 jobs required Day

Alternatives

If Claude API is restricted, the following alternatives may be considered:

  • OpenAI GPT-4/GPT-3.5Powerful alternatives
  • Google Gemini: Multiple Modular Capability
  • Open source modelLocal deployment: Llama 3, Mistral, Qwen
