Gonka AI Trial Key + Pricing Web Form | n8n Workflow

Get a Gonka trial key, live model list, and pricing—then wire it into an n8n AI chat agent

This n8n workflow automatically generates a Gonka AI Trial Key via a web form, pulls available model IDs and current token pricing, and then sets you up with an AI Agent routed through an Anthropic Chat Model using Gonka’s base URL.

What this workflow does

• Collects user input through an n8n Form submission where the user selects a fuel option.
• Requests a trial API key by calling the Gonka MCP endpoint to retrieve a trial key (e.g., gc-…) and recommended model details.
• Fetches current pricing by calling the Gonka MCP endpoint again to obtain up-to-date token pricing.
• Combines setup details into a single formatted “receipt” object containing: the trial key, model availability, limits/expiry info, and pricing.
• Shows a completion screen with the trial key, the OpenAI/Anthropic base URLs, available models, pricing, and a signup link for a permanent key.
• Exposes a public chat endpoint that forwards incoming chat messages into an n8n AI Agent powered by an Anthropic Chat Model.

Use cases

• Launch a self-serve onboarding flow for customers who need a Gonka trial key plus pricing visibility.
• Provision an AI chat experience quickly by combining key generation + model/pricing display + a ready-to-use webhook.
• Test and validate Gonka model availability inside n8n before switching from trial to permanent keys.

Technical details

• Integrations/nodes: form, form trigger, http request, code, sticky note, and n8nn8n-nodes-langchainagent (AI Agent).
• Gonka MCP endpoints: used to request trial key + retrieve pricing information.
• Anthropic Chat Model configuration: set Base URL to https://gate.joingonka.ai and paste your Gonka key (trial gc-… or permanent jg-…).
• Chat entry point: use the public chat webhook URL from the chat trigger as the message endpoint for the AI Agent.
