Introduction

The GET /offers endpoint now returns the best competing offer found on external marketplaces for each of your offers.

This gives sellers direct access to competitive pricing data without leaving the API.

What changed?

A new externalCompetingOffer object has been added to the offer response. When available, it exposes the best competing offer detected on an external marketplace, including pricing details and a price index relative to your own offer.

The object includes the following fields:

  • marketplaceName — the external marketplace where the competing offer was found (e.g. AMAZON)
  • price — the competitor’s base price
  • deliveryCost — the competitor’s delivery cost
  • totalPrice — the competitor’s total price (base price + delivery)
  • priceIndex — your offer’s total price expressed as a percentage of the competitor’s total price. A value above 100 means your offer is more expensive; below 100 means you are cheaper
  • updatedAt — the timestamp of the last competitive data refresh

The field is absent when no external competing offer has been detected for a given product.

Example

"externalCompetingOffer": {
  "marketplaceName": "AMAZON",
  "price": 42.49,
  "deliveryCost": 0,
  "totalPrice": 42.49,
  "priceIndex": 101.98,
  "updatedAt": "2026-07-13T16:11:30Z"
}

In this example, the seller’s total price is approximately 2% higher than the best Amazon offer at the time of the last data refresh.

Why it matters

Sellers can now integrate competitive pricing signals directly into their repricing workflows, ERP, or OMS — without relying on separate market monitoring tools. By exposing the priceIndex, the API makes it straightforward to identify offers that are losing ground on price and act accordingly.
