Formspree → Claude API → Two-Path Email Automation (Carriers OR Customer)

I need an automation that does this: Trigger: Customer submits booking via Formspree webhook Step 1: Send to Claude API: My full carrier list 800+ carriers with name, email, location Pickup ZIP and Delivery ZIP from the form Vehicle type Prompt for Claude: "Here are my carriers. Here is a route from pickup_zip to delivery_zip for a vehicle_type. Which carriers from this list would realistically run this route? Return their names and emails in JSON format. Step 2: Based on form field booking_type: If standard: Email each matched carrier asking for rate and availability If direct_access: Email the CUSTOMER a list of matched carriers with their contact info Important: I do NOT have carriers pre-mapped by coverage area. Claude figures it out naturally from names, locations, and context. This must work without pre-mapping. Tech stack preferred: n8n has native Claude node or Make.com Deliverables: Working automation Both email templates editable by me Documentation Budget: $300-400
