Example request
“Compare prices for the same items across these stores. Show the differences and when each price was checked.”
How it works
- Define the comparison. Choose the services, items, location, and fields to collect. Use the same filters for each source so the results are comparable.
- Collect and normalize. Read the supported search or detail endpoints. Keep source IDs and timestamps, normalize units, and mark missing values instead of filling them in.
- Build the report. Calculate differences and export a table or chart. Repeat the same query over time to track changes, keeping failed requests separate from real changes.
What you’ll need
Search and detail operations for your sources, plus your own storage and reporting code. Data coverage and request limits depend on the connector.
Check supported sites for service availability, then make your first authenticated request.
