💰 Pricing

You pay $0.40 per 1,000 results ($0.0004 per product, review or monitor row), plus a small platform usage fee for compute and proxy traffic. In our tests that fee was about $0.001 for 1,000 listed products and about $0.008 for 1,000 full product pages.

Example: 1,000 products from a category ≈ $0.40 + $0.001 = about $0.40. Rows that are filtered out, not found or unchanged in monitor mode are never charged. Set a maximum cost per run and the scraper stops cleanly when it is reached.

❓ FAQ

Is it legal to scrape iHerb? The scraper only reads public data that any visitor can see without logging in. Check iHerb's terms and your local laws for how you use the data, especially reviewer names.

Do I need an account, cookies or a proxy? No account or cookies. Datacenter proxies are on by default and work well; if iHerb ever refuses them, the run switches to US residential proxies by itself.

How many results can I get? A whole category or search (iHerb lists up to about 45,000 products), and up to 10,000 reviews per product for each language, star rating and order.

Why is a field empty? iHerb does not publish everything for every product: stockQuantity only appears when stock is low, expiryDate only for products with a best-by date, upc and supplement facts only in full details mode.

How does the monitor work? Run the scraper in monitor mode on a schedule. Each run compares prices and stock with the previous run for the same country and currency and saves new_item, price_drop, price_increase, out_of_stock, back_in_stock or removed rows. Up to 30 checks of history are kept per product.

Can I schedule it or use the API? Yes. Schedule runs in the console, call the run API, and connect the results to webhooks and integrations.

⚠️ Limits

• Country stores sell different products: a product that is not sold in the selected country is skipped and reported in the run summary.
• Review pages go up to 10,000 reviews per product for each filter combination.
• iHerb does not display every currency in every market; when it falls back to US dollars, the prices are US dollars.
• soldLast30Days is iHerb's rounded figure (for example 50,000+), not an exact count.
• The monitor keeps one history per country and currency in your account storage; delete the iherb-price-monitor store to start over.
• Questions and answers, and per-review comments, are not scraped.
