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:

1. Import the workflow JSON into your n8n instance

2. Configure Anthropic API credentials:

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

3. (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

4. Customize the form (optional):

   • Edit form fields in “On form submission” node
   • Add industry-specific questions
   • Adjust required fields based on your needs

5. Test the workflow:

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

6. Customize agent prompts (optional):

   • Adjust system messages for industry-specific requirements
   • Modify scoring criteria in Agent 3
   • Add custom validation rules in Agent 2

7. 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)
