Missing "Base URL" Setting in OpenRouter Chat Model Node

Questions
1

Hi,
Thanks for adding the OpenRouter Chat Model node.

Describe the problem/error/question

I couldn’t find the “Base URL” setting mentioned in the documentation. It’s not available in the node itself or in the OpenRouter credentials. This setting could be useful, for example, when using OpenRouter with Helicone.

Information on your n8n setup

  • n8n version: 1.77.3
  • Running n8n via n8n cloud

Is there a way to set it up?

Thanks.

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:

I am also facing this issue

Just ran into this problem too.

Base URL is missing from OpenRouter and an option to add custom headers (also missing from the OpenAI node). Helicone-Auth Header is needed in the requests.

Just to clear this up, this isn’t a bug it just isn’t implemented. Is there a reason why OpenRouter would need a base url?

Most services implement the OpenAI spec and the OpenAI node does have the url option available.
