Use OpenRouter Models Parameter

Questions

Describe the problem/error/question

I want to use the models parameter in the open router note but I only find a model parameter. (Model Routing | Dynamic AI Model Selection and Fallback | OpenRouter | Documentation)

How can I use this. This is a really important parameter.

It looks like your topic is missing some important information. Could you provide the following if applicable.

  • n8n version:
  • Database (default: SQLite):
  • n8n EXECUTIONS_PROCESS setting (default: own, main):
  • Running n8n via (Docker, npm, n8n cloud, desktop app):
  • Operating system:

Hey @Dimitrij_Ovtcharov, the OpenRouter node does not support the models parameter (but you already know that, hopefully it will one day). But as a workaround you can make a direct API request using n8nā€™s HTTP Request node:

  • Method: POST
  • URL: https://openrouter.ai/api/v1/chat/completions
  • Headers:
{
  "Authorization": "Bearer YOUR_API_KEY",
  "Content-Type": "application/json"
}
  • Body (JSON):
{
  "models": ["mistral", "gpt-4-turbo", "claude-3-opus"],
  "messages": [
    {"role": "system", "content": "[YOUR SYSTEM PROMPT"},
    {"role": "user", "content": "[YOUR USER PROMPT]"}
  ]
}

Can this option be used in any way to replace the model node in an AI agent?
