Dynamic Restaurant Menu Pricing with Claude & QR Menu API

Dynamic restaurant menu pricing—approved by Claude, delivered via your QR menu API

This n8n workflow recalculates restaurant dish prices every 15 minutes using POS order velocity, local weather, and nearby events/foot-traffic signals—then sends proposed changes to Anthropic Claude to flag brand-damage risk before pushing approved prices to your QR-code digital menu via API.

What this workflow does

• Runs on a 15-minute schedule to start each pricing cycle automatically.
• Fetches real-time inputs via HTTP APIs:
  • POS order-velocity data
  • Current local weather
  • Nearby events and foot-traffic data
• Derives per-dish demand features (e.g., velocity ratio plus weather and event multipliers).
• Applies an elasticity-based pricing model to propose dish price changes within defined surge/discount caps.
• Submits proposed changes to Anthropic Claude to approve, cap, or reject each update with a short risk rationale.
• Parses Claude’s JSON decisions with a safety fallback that keeps current prices if the AI output can’t be parsed.
• Posts final approved prices to the QR/digital menu platform’s price-update API.

Use cases

• Restaurants with high demand variance (lunch vs. dinner, weekends, event nights) that want pricing to react to velocity and local context.
• Operators testing promotion strategies while enforcing caps to prevent overly aggressive discounting or surges.
• Teams aiming for safer automated updates by using Claude as a brand-damage guardrail before QR menu price changes go live.

Technical details

• n8n nodes/tools: code, wait, merge, sticky note, http request, and n8n-nodes-langchainagent (LangChain agent wrapper).
• Integrations: HTTP APIs for POS, weather, and events/foot-traffic; Anthropic Claude for approval/risk review; QR/digital menu price-update API for publishing results.
• Setup inputs: configure Anthropic API credential and select the Claude model; provide POS/weather/events API endpoints and bearer tokens (e.g., YOUR_POS_API_KEY, YOUR_WEATHER_API_KEY).
