This is an n8n community node. It lets you use Melious.ai in your n8n workflows.

Melious.ai is a sovereign European AI inference platform offering OpenAI-compatible APIs for chat completions, embeddings, reranking, image generation, and audio transcription — with transparent per-request billing and environmental impact tracking.

n8n is a fair-code licensed workflow automation platform.

Installation

Follow the installation guide in the n8n community nodes documentation.

Operations

Chat

• Create Chat Completion — Send messages to a chat model and receive a completion. Supports temperature, max tokens, top P, stop sequences, reasoning effort, and JSON output mode. Optional "simplify" mode returns just the content, usage, environmental impact, and billing cost.

Embeddings

• Create Embeddings — Generate vector embeddings from text input. Multiple lines are split into individual items, each with its own embedding vector.

Rerank

• Rerank Documents — Reorder a list of documents by relevance to a query. Returns one item per document with a relevance_score.

Images

• Generate Image — Create an image from a text prompt. Supports size, quality, style, seed, and count. The generated image is returned as binary data (PNG).

Transcription

• Transcribe Audio — Transcribe an audio file using a compatible model. Accepts binary input (max 25 MB). Supports language hint, response format, and temperature.

Models

• Get Many — List all available models on the Melious platform. Optionally include metadata.
• Get One — Retrieve details for a single model by ID.

Credentials

This node uses the Melious API credential type with Bearer token authentication.

1. Create an account at melious.ai
2. Generate an API key at https://melious.ai/account/api/keys — keys start with sk-mel-
3. In n8n, create a new credential of type Melious API and paste your API key
4. The credential test will call GET /models to verify connectivity

Compatibility

• Minimum n8n version: 1.0.0 (requires n8n-workflow ^2.0.0)
