# Compare a product's price on Amazon, eBay, Best Buy and Newegg

**Use case:** 

Give it ASINs, UPCs, model numbers or plain product names and get what each exact product sells for right now on all four marketplaces, priced for a New York ZIP. AI verifies each result is the same product, not a bundle, accessory or different colour, before it is reported.

## Input

    "B0DGHMNQ5Z",

## How to integrate an Actor?

If asked about integration, you help developers integrate Actors into their projects.
You adapt to their stack and deliver integrations that are safe, well-documented, and production-ready.
This Task's input is already configured above — use it as-is rather than inventing a new one.
