LibreChat API: FreeTheAI Custom Endpoint (librechat.yaml)

LibreChat adds FreeTheAI as a custom endpoint in librechat.yaml. With fetch on, it lists every model your key can use.

Steps

Add your key to .env
Put your key in LibreChat's .env file.
bash
```
FREETHEAI_API_KEY=ftai_your_key_here
```

Add the endpoint to librechat.yaml

Add FreeTheAI under endpoints.custom.

yaml

endpoints:
  custom:
    - name: 'FreeTheAI'
      apiKey: '${FREETHEAI_API_KEY}'
      baseURL: 'https://api.freetheai.org/v1'
      models:
        default: ['glm-5.3']
        fetch: true
      titleConvo: true
      titleModel: 'current_model'
      modelDisplayLabel: 'FreeTheAI'

Restart LibreChat
Restart the server (or the Docker containers) so it reads the new config, then pick FreeTheAI in the endpoint menu.

How this guide was checked: Checked against LibreChat's librechat.example.yaml (custom endpoints) on 2026-09-29.

Tips

With Docker, make sure librechat.yaml is mounted into the container.

Troubleshooting

LibreChat does not show the FreeTheAI endpoint. Why?

LibreChat only reads librechat.yaml at startup. Restart it and check the logs for YAML errors.

Common errors

401: the key is wrong or incomplete. Paste the whole key.
403: follow a provider of the model, or confirm your email.
404: the model ID or URL is wrong.
429: daily limit reached, or too many requests at once.
