Setup Instructions

PREREQUISITES: Anthropic API key (Claude Sonnet 4.5 access) PostgreSQL/MySQL database (optional, for auto-execution) n8n version 1.0+ with LangChain nodes

CONFIGURATION STEPS:

Import the workflow JSON into your n8n instance

Configure Anthropic API credentials: Add your Anthropic API key in n8n credentials Connect all 4 AI model nodes to your credential

(Optional) Configure database connection: In "Execute SQL in PostgreSQL" node, add your database credentials Use a TEST/SANDBOX database, never production Or disable this node if you prefer manual execution

Customize the form (optional): Edit form fields in "On form submission" node Add industry-specific questions Adjust required fields based on your needs

Test the workflow: Use the form URL to submit a test request Check execution time and quality Verify all agents are responding correctly

Customize agent prompts (optional): Adjust system messages for industry-specific requirements Modify scoring criteria in Agent 3 Add custom validation rules in Agent 2

Deploy: Share the form URL as your lead magnet Embed in website or landing pages Set up email notifications for submissions

COST CONSIDERATIONS: Each execution costs ~$0.15-0.30 in API calls Failed attempts (retries) increase cost Consider rate limiting for public forms

Requirements

REQUIRED: Anthropic API Key (Claude access) n8n version 1.0+ LangChain nodes enabled

OPTIONAL: PostgreSQL/MySQL database connection (for auto-execution) Email service (for result delivery) CRM integration (for lead capture)
