Hey @LiviaH! 👋 I'm here to assist you with bug fixes, answer your questions, and help you become a contributor. Let's tackle this issue together!

I couldn't find specific information about the status code 402 in the context of Dify's OpenRouter integration. However, I did find a similar closed issue related to setting the OpenAI API key, which might provide some insights or potential solutions. You can check the closed issue here and see if any of the discussions or solutions there are applicable to your situation [1].

If the issue persists, consider checking if there are any recent changes or updates in Dify version 0.11.0 that might affect the OpenRouter API key validation process, as this could be a contributing factor.

To continue talking to Dosu, mention @dosu.

issue #1526 is not similar, you mix OpenRouter and OpenAI integration which are different cases. I assume the OpenRouter specific implementation needs to reviewed.

Hi, @LiviaH. I'm Dosu, and I'm helping the Dify team manage their backlog. I'm marking this issue as stale.

Issue Summary:

  • Bug reported in Dify version 0.11.0 regarding OpenRouter setup.
  • Error encountered: "Credentials validation failed with status code 402" when saving an API key.
  • I suggested checking a similar issue, but you clarified the difference and pointed out the need for a review of the OpenRouter-specific implementation.
  • The issue remains unresolved, requiring further investigation into the OpenRouter integration.

Next Steps:

  • Please confirm if this issue is still relevant to the latest version of the Dify repository. If so, you can keep the discussion open by commenting here.
  • If there is no further activity, this issue will be automatically closed in 15 days.

Thank you for your understanding and contribution!

Still the same behavior in dify.ai 14.2. openrouter is on the list of model providers but is not usable. Adding the API Key is not possible and produces an error with the message "Credentials validation failed with status code 402"

This issue is still encountered in Dify version 0.15.3, i.e., the OpenRouter API Key cannot be configured, but a single model can be added successfully
