Market Capture
Market Capture is a standalone Chrome extension (v0.6) that captures Amazon product-detail-page evidence into a JSON package. It is independent of AP4, never modified by the Hosted Build OS, and has no field for a Shopify store's own brand -- everything it captures is evidence, not confirmed Product Truth.
1. Install the extension (local/unpacked)
- Download the extension folder: Download market-capture-extension.zip
- Unzip it somewhere on your machine.
- Chrome →
chrome://extensions→ enable Developer mode. - Click Load unpacked → select the unzipped
market-capturefolder.
No Chrome Web Store package exists yet -- this is the only install path in this phase.
2. Capture one product
- Open a supported Amazon product page (amazon.com/.ca/.co.uk/.de/.co.jp, a
/dp/,/gp/product/, or/clp/URL). - Click the toolbar icon to open the side panel → Capture Current Page.
- Review the capture card (View JSON / Copy JSON), or click Add to Batch to keep going.
3. Capture a batch
- Repeat "Capture Current Page → Add to Batch" across as many Amazon products as you want.
- The batch list at the bottom of the side panel shows every product captured so far.
- Click Download Batch JSON for one file containing every captured product (
market_capture_batch_v1).
4. Upload to a project
Upload either a single-product JSON (market_capture_v1) or a batch JSON (market_capture_batch_v1) -- the importer auto-detects which shape you gave it.
