Node: OpenRouter

Sends a prompt to any model available on OpenRouter and returns the completion.

Parameters

| Parameter | Description | |-------------------|--------------------------------------------------------------| | Output Modalities | Filter the model list by capability (text, image, audio…) | | Model | Dynamically loaded from OpenRouter based on modality filter | | Prompt | The message to send to the model | | Max Tokens | Cap on generated tokens (default: 1024) | | Temperature | Randomness of output, 0–2 (default: 0.7) |

Output

Returns the full OpenRouter API response as JSON, including choices[0].message.content with the model's reply.

Example Workflow

A simple workflow that takes a prompt from a manual trigger and sends it to an AI model:

[Manual Trigger]
  → [OpenRouter] (model: google/gemini-flash-1.5, prompt: "Summarize the latest AI news")
  → [Set] (extract: {{ $json.choices[0].message.content }})

To import: copy the JSON below and use Workflows → Import from clipboard in n8n.
