📊 Keepa API — Daily BSR Auto-Refresh
Keepa's API fetches live BSR, pricing, ratings, and 30/60/90-day history for all your ASINs automatically.
Data will refresh on your chosen schedule without you having to upload a file manually.
📍 API credentials are stored on this device only. They need to be entered once per device/browser.
Your Keepa key is at keepa.com → Account → API.
After entering credentials, click ☁️ Push Creds to Worker so the worker can run 24/7 without the page open.
Keepa API Access Key *
Get your key at keepa.com/#!api →
Account → API Access Key. Keys look like a 64-character alphanumeric string.
Keepa API costs ~$19/mo for 1 M tokens (each ASIN product query uses ~1–2 tokens).

🏪 Amazon Vendor Central API — Real-Time Sales Data
Connect to Amazon's Selling Partner API (SP-API) with Vendor Central credentials to pull
real-time ordered revenue, shipped units, and ASIN-level sales data directly into each product card.
📍 Where to put your Amazon SP-API credentials: Fill in all four fields below. These are found in your
Vendor Central
account under Settings → Account Info → Developer API access, or via the
SP-API Developer Console.
All credentials are stored locally in your browser only.
Client ID (LWA) *
Login With Amazon (LWA) Client ID from SP-API Developer Console
Client Secret (LWA) *
Login With Amazon Client Secret. Keep this private.
Refresh Token *
Generated during SP-API OAuth authorization flow. Starts with Atzr|
Marketplace ID *
Select your marketplace above, or type a custom ID. The ID must match the marketplace your vendor account is registered in. Still getting marketplace errors? Your vendor account may be registered to a region-specific sub-marketplace.
Contact your Amazon Vendor Manager and ask: "What is the SP-API marketplaceId for my vendor account amzn1.vg.4035400?"

Step 3 — Register Amazon notification endpoint:

https://little-sun-1ec4.alex-28a.workers.dev/notify?secret=YOUR_SECRET
How to get your SP-API credentials:
1Log into Vendor Central → Settings → Account Info → Developer Central
2Create a new SP-API application (or use existing). Note the Client ID and Client Secret
3Run the OAuth authorization flow to generate a Refresh Token for your Vendor account
4Paste all three values above + save. The dashboard exchanges your refresh token for access tokens automatically.
⚠️ CORS note: Amazon's SP-API requires server-side token exchange. If you're running this file locally,
the API calls will be blocked by CORS. To use live SP-API data, host this dashboard on a small proxy server or use
AWS API Gateway as a pass-through.
The credentials panel will still save and store your keys — toggle "Demo Mode" below to preview with sample data.
