Shein Price & Stock Monitor

Monitor Shein product prices and stock from a watchlist of product page URLs. Each run fetches the current sale price, retail price, discount percentage, flash-sale status, and per-variant stock for every URL in your list. Price changes are detected by comparing to the previous run.

Built for dropshippers, resellers, and pricing analysts running scheduled monitoring workflows.

What it does

• Fetches each Shein product detail page (PDP) via Bright Data Web Unlocker — the only path that clears Shein's Halo anti-bot server-side
• Extracts sale price, retail price, discount percentage, flash-sale price and end time, in-stock status, per-variant stock map, and low-stock hints
• Detects price changes by comparing sale_price to the previous run's recorded price (stored in the run's Key-Value store)
• Emits one dataset record per URL with price_changed (bool) and price_delta (number) fields

Scheduling for continuous monitoring

This actor is designed to be run on a schedule (e.g. every 6 or 24 hours). Each run compares prices to the previous run's values and populates price_changed and price_delta. Use Apify's built-in scheduler or an external cron job to automate.

On the first run, price_changed will be false and price_delta will be 0 for all records (no previous data to compare against).

Region support

The region input controls the currency code in the currency output field. URLs must match the selected region's Shein domain (e.g. us.shein.com for us, shein.co.uk for uk). The actor auto-detects the region from the URL hostname if not specified.

Supported regions: us (USD), uk (GBP), de / fr / es / it (EUR), au (AUD), ca (CAD).

Limitations

• Only product detail pages (PDP) are supported — not category or search pages
• Each URL consumes one Bright Data Web Unlocker request
• Price history is limited to the previous run's values; longer history requires external storage
