How this service works
Get a product's full details along with the price history of each offer/store selling it. The response mirrors the Product Details endpoint, with every entry in the `offers` array additionally enriched with its dated `price_history`. Use the `page` parameter to page through the offers (page 1 returns the top offers, subsequent pages return additional stores/offers).
Output
A JSON object containing full product details mirroring the Product Details endpoint, with the offers array enriched so each offer includes a price_history array of dated price points. Each offer also contains current price, original price, sale status, shipping details, store name, store rating, store review count, payment methods, product condition, and a link to the offer page. Results are paginated; page 1 returns top offers and subsequent pages return additional stores.
Example use cases
Spot a price drop before buying
“I'm thinking of buying this product — its ID is B08N5WRWNW. Can you check the price history across stores in the US so I can see if the current price is actually a good deal or if it usually sells cheaper?”
Monitor seasonal pricing trends
“I want to understand how the price of product ID 12345678 has fluctuated over the past year across different retailers. Can you get me the full price history for all offers in the US?”
Validate a claimed sale discount
“This listing says it's 40% off but I'm skeptical — can you pull the price history for product ID B07XJ8C8F5 and tell me what the original price was and whether it's actually lower than usual right now?”
Technical details
Endpoint
GEThttps://agents.openwebninja.com/realtime-product-search/v2/product-price-history-v2?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need to see how a product's price has changed over time across multiple stores, not just the current price. It is the right choice when evaluating whether a current price is a genuine discount, when tracking price volatility for a product, or when comparing historical price trends across sellers. Prefer this over the basic Product Details endpoint whenever temporal price data is needed rather than just a snapshot.
