Price Monitor

Pricing Analytics for Amazon Sellers

Connect your Amazon seller account to get real-time pricing context, change alerts, and price history for the listings in your own catalog. Price Monitor accesses Amazon SP-API data on behalf of the authorized seller — we do not aggregate, store, or resell data across multiple sellers. Free for a limited time.

Authorize with Amazon

You'll be redirected to Amazon Seller Central to authorize access. We only request read-only pricing data scoped to your own catalog.

What You Get

Pricing Context for Your Listings

Track pricing context for the ASINs in your own catalog. See how the offers competing on your listings change over time, retrieved on your behalf via SP-API.

Price Change Alerts

Get notified when pricing on your watchlisted ASINs crosses your thresholds. React to changes on your own listings as they happen.

Pricing Analytics

Access pricing trends and analytics for your own catalog to make smarter pricing decisions on the listings you own.

Large Catalog Support

Monitor your full catalog, regardless of size. Our infrastructure handles pricing data for the seller's own listings — whether that's hundreds or hundreds of thousands of SKUs.

Free for a Limited Time

No credit card, no trial period. Paid tiers coming later — early users get grandfathered rates.

Read-Only, Scoped to Your Catalog

We only access SP-API pricing data scoped to your own catalog on your behalf. We never modify your listings, inventory, or account settings, and we do not aggregate or resell data across sellers.

How it works

  1. Click "Authorize with Amazon" above. You'll land on Amazon Seller Central's consent screen.
  2. Review the permissions. We request read-only pricing data scoped to your own catalog — no ability to modify listings, inventory, or orders.
  3. Approve and return here. Amazon sends you back to our app with a secure authorization code.
  4. We set up your account. Within minutes, the ASINs in your own catalog start appearing in your dashboard with real-time offer tracking on those listings.
  5. Get alerts immediately. Price changes on your listings hit your inbox (and dashboard) as they happen.

Setup takes less than 60 seconds. Free for a limited time.
