Agent Linking Different Receipt Product Names to the Same Item Across Stores

This is an example of comparing shopping carts where the agent finds and links existing items when product names on receipts differ by store.

n8n

How it works

  1. Connect receipt data, a stored product search tool, and records for price comparison.
  2. The agent repeatedly calls the stored product search tool to link product names that differ by store to existing items.

Results

The intended outcome in the public example is receipt items linked as the same product.

Notes

The agent's role is to verify product identity. Calculating and comparing personal prices and the US CPI are separate code steps and do not use South Korean price data. The author reports that public settings and tool connections were checked, but the process was not executed directly.

Goal: Find the same products on receipts to compare prices in the shopping cart.

Input & Environment: [Sample receipt], [Product list], [Product search connection], [Currency & quantity units].

Reference original: https://n8n.io/workflows/20532

With the public configuration from the original, prepare the settings and connections so a test environment can be created. If there are missing sub-workflows, APIs, or account permissions, mark them as incomplete until actually connected.

Connections and data to prepare: Connect receipt data, a stored product search tool, and records for price comparison.

Agent behavior to implement: The agent repeatedly calls the stored product search tool to link product names that differ by store to existing items.

Scope of operation: The agent's role is to verify product identity. Calculating and comparing personal prices and the US CPI are separate code steps and do not use South Korean price data.

The result is receipt items linked as the same product. Please also organize the required setup steps and actual execution method. After checking the results returned by the tool, choose the next task, and separately note any data that could not be accessed or tasks that could not be executed.

Verification: Distinguish between products with similar names but different sizes, and if a match is unclear, do not confirm as a new product but leave it for review. Show the input used for verification, the actual output, and distinguish any items not yet verified.
