Description

@opperai/n8n-nodes-opper

This is an n8n community node for Opper — the AI gateway for agents. It gives your n8n workflows access to 300+ AI models (Anthropic, OpenAI, Google, Mistral, and many more) through one EU-hosted, GDPR-compliant gateway, with unified billing, tracing, and Opper’s control plane (Route, Observe, Steer, Guard, Comply).

n8n is a fair-code licensed workflow automation platform.

Installation

Follow the installation guide in the n8n community nodes documentation:

Settings → Community Nodes → Install and enter @opperai/n8n-nodes-opper.

Nodes

Opper Chat Model

A chat-model sub-node, used the same way as the built-in OpenAI / OpenRouter chat model nodes: attach it to an AI Agent, Basic LLM Chain, or any other node that accepts a language-model connection.

  • The model dropdown is loaded live from Opper’s catalogue — pick any of 300+ models by their Opper ID (e.g. anthropic/claude-sonnet-4-6, openai/gpt-5-nano, mistralai/mistral-large-eu).
  • Supports the standard sampling options (temperature, top-p, penalties, max tokens), JSON mode, timeouts, and retries.
  • Credentials

    Create an Opper API credential:

    | Field | Value |
    |—|—|
    | API Key | Your Opper API key (op-…) from platform.opper.ai |
    | Base URL | https://api.opper.ai/v3/compat (default — leave as is) |

    The credential test calls Opper’s OpenAI-compatible GET /models endpoint.

    Why Opper?

  • EU-hosted, GDPR-compliant: inference routed and processed in the EU.
  • One key, 300+ models: no per-provider accounts or keys.
  • Unified billing and cost tracking across all providers.
  • Control plane: routing, observability/evals, steering, guardrails, and compliance controls on top of every call.
  • Compatibility

    Requires n8n version 1.94.0 or later (community sub-node support). Node.js 20.15+.
