n8n

Call any model from n8n workflows.

n8n's OpenAI credential accepts a custom base URL, which makes every evolved.to model available to your workflows.

Create a credential

  1. Add a new credential

    In n8n, open Credentials, click Create, and choose OpenAI.

  2. Fill in the details

    Paste your evolved.to key as the API Key and set Base URL to https://api.evolved.to/v1. Save, and n8n tests the connection automatically.

Use it in a workflow

Add an OpenAI Chat Model node (or an AI Agent with a chat model), select the credential, and set the model By ID, for example gpt-5-mini for high-volume steps or claude-sonnet-5 for heavier reasoning.
