Prerequisites
You need an AskArc API key to use this node:

- You can also add your own custom models through the portal
Credentials
| Field | Description |

When you add credentials, n8n will test them automatically by calling the List Models endpoint.

List Models
Returns all available AI models. Each model is emitted as a separate n8n item with fields: id, name, provider, pricing, contextWindow, and supportsImages.
AI Agent Compatibility
This node has usableAsTool: true, so it can be used as a tool inside n8n AI Agent nodes. The Chat Completion operation works as a tool that AI agents can call to get responses from AskArc models.
