I'm an AI assistant - my answers may be incorrect and I cannot see screenshots. Please verify information with the OpenRouter docs.

To help debug this issue, I need more information:

  • What is the exact model identifier you're trying to use?
  • Can you share the full request (without your API key) and the full error response?
  • What are you trying to accomplish with this API request (e.g., chat, image generation, etc.)?

These details are essential for troubleshooting and will help the support team or mods if escalation is needed.

The error "The request is prohibited due to a violation of provider Terms Of Service. (4028)" when using the model identifier anthropic/claude-sonnet-4 usually indicates your request is not allowed by Anthropic's or OpenRouter's terms. Common reasons include:

  • Attempting to use the model from a restricted region/country
  • Sending content or prompts that violate Anthropic's acceptable use policies
  • Using the model in a way not permitted by Anthropic or OpenRouter (such as certain commercial uses or automated scraping)

You can find more information about this model and its capabilities at Claude Sonnet 4. If you believe you are not violating any terms, please double-check your usage against the provider's guidelines and the OpenRouter documentation.

If you continue having this issue and are sure you’re not violating any terms, please provide:

  • The exact prompt/content you are sending
  • Your approximate region/country
  • Whether you are on a paid or free account

For persistent issues, contact a mod in Discord for further review.

Your error message shows a 401 Unauthorized error:

401 Missing Authentication header

This means your request is missing the required API key.

According to the documentation:
"Include your API key in the Authorization header as Bearer YOUR_API_KEY."
Example:

Authorization: Bearer sk-or-v1-your-key-here

You can verify your API key at openrouter.ai/keys and ensure you have sufficient credits in your account. If your key is expired or revoked, generate a new one.
Source: Integration Guide

Make sure your request includes this header. If your issue persists after adding the correct header and key, double-check the model identifier and your account status.
