n8n

Reviewed by Proof · Updated

Definition

n8n is a workflow automation tool whose OpenAI credential has a Base URL field, so its OpenAI nodes can call luv13.

Key takeaways

  • Create an OpenAI credential in n8n and set Base URL to https://api.luv13.ai/v1.
  • Paste your luv13 key into API Key. Leave Organization ID empty.
  • Use that credential in chat-based OpenAI nodes, such as the OpenAI Chat Model node, and pick a luv13 model id like luv13/glm-5.3-flash.
  • Nodes that need endpoints luv13 doesn't serve, such as embeddings, images or audio, won't work with it.
  • The field names come from n8n's own OpenAI credential definition.

Setup

  1. In n8n, go to Credentials and add a new OpenAI credential.
  2. Fill in:
    • API Key: your luv13 key
    • Organization ID: leave blank
    • Base URL: https://api.luv13.ai/v1
  3. Save the credential.
  4. Add a chat node that uses OpenAI credentials, such as OpenAI Chat Model in an AI Agent or chain workflow, and select your luv13 credential.
  5. Set the model to a luv13 id, such as luv13/glm-5.3-flash.

What works and what doesn't

luv13 serves GET /v1/models and POST /v1/chat/completions. Features that call other OpenAI endpoints, such as the Embeddings OpenAI node or image and audio actions, return errors because luv13 doesn't serve those paths. See Endpoints.

Check your settings first

If a workflow fails, test the same key and model outside n8n:

curl https://api.luv13.ai/v1/chat/completions \
  -H "Authorization: Bearer $LUV13_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{"model": "luv13/glm-5.3-flash", "messages": [{"role": "user", "content": "Hi"}]}'
