# Use AxForge with n8n

    n8n builds automations out of nodes. Its OpenAI
    credential takes a **Base URL**, so every OpenAI node in your workflows (chat models, AI agents) can run on
    AxForge.

    **Before you start**

        - An AxForge API key. Get one (a minute).

        - n8n, on n8n Cloud or your own machine. This guide was tried with n8n 2.43.7 on 2026-10-17, started
        with Docker:

```
docker run -it --rm -p 5678:5678 -v n8n_data:/home/node/.n8n docker.n8n.io/n8nio/n8n
```

## Set it up

### Make an OpenAI credential for AxForge

In n8n go to **Credentials** → **Create credential**, choose **OpenAI**. Paste your key in
        **API Key** and change **Base URL** to `https://api.axforge.ai/v1`. Press
        **Save**.

### n8n tests it

On save, n8n calls AxForge with the key. **Connection tested successfully** means it works.

### Build a chat workflow

In a new workflow add the trigger **When chat message received**, then an **AI Agent** node. On
        the agent's **Chat Model** connector add **OpenAI Chat Model**.

### Choose the credential and the model

Open the **OpenAI Chat Model** node. **Credential**: the one from step 1. **Model**: n8n lists
        our models; pick `qwen3.8-27b-nvfp4`. **Use Responses API** may stay on: AxForge serves that
        API too.

### Open the chat and ask

Press **Open chat** under the canvas and type a question. The answer comes from AxForge, and the log
        beside it shows each step.

## The settings

        | Field | Value |  |

        | Credential type | OpenAI |  |

        | API Key | your AxForge key |  |

        | Base URL | https://api.axforge.ai/v1 |  |

        | Model | qwen3.8-27b-nvfp4, glm-5.3-flash or mimo-v2.6-flash |  |

Which model for what: `qwen3.8-27b-nvfp4` is the
    everyday default and reads images, `glm-5.3-flash` thinks before it answers,
    `mimo-v2.6-flash` is the fastest. The same credential works in n8n's other OpenAI nodes.

## Check that it works

    The credential says **Connection tested successfully**, the model list shows our models, and
    the chat gets an answer. The calls show in the console under
    API Keys → Recent calls within a minute.

## When it does not work

      | What you see | What it means | Fix |  |

        | "Couldn't connect with these settings" | the Base URL or the key | the URL is `https://api.axforge.ai/v1`; paste the key again, whole |  |

        | OpenAI's models in the model list | the node uses another credential | choose the AxForge credential in the node |  |

        | The test chat does not answer on a self-hosted n8n | n8n's own address is not the one in your browser | start it with `WEBHOOK_URL` set to the address you open it on |  |

    Test a call says in one click whether a problem is your key,
    your balance or us.
