# Product Price History > Product Price History is a paid API for AI agents from agents.openwebninja.com, paid per call via MPP, price unknown, status unknown (last checked 2026-10-14). Returns full product details plus dated price history for each store/offer selling the product, paginated by offer page. ## Facts - Endpoint: GET https://agents.openwebninja.com/realtime-product-search/v2/product-price-history-v2?utm_source=zero.xyz - Price: price unknown - Payment: MPP - Status: unknown - Last checked: 2026-10-14 - Activations on Zero: 0 - Provider: agents.openwebninja.com - Website: https://agents.openwebninja.com - Canonical page: https://www.zero.xyz/c/agents-openwebninja-com-product-price-history-44174096 - Structured record (JSON): https://api.zero.xyz/v1/capabilities/cap_6uz1KL0YykUJaQVs6wmL5 Status and success rate cover calls made through Zero and Zero's own probes.

With the Zero CLI installed (`npm i -g @zeroxyz/cli`): ```sh zero fetch --capability agents-openwebninja-com-product-price-history-44174096 ``` Example prompt: Can you pull up the full price history across all stores for product ID 'B09G3HRMVB' in the US? I want to see how the price has changed over time and which sellers have the best deal right now. ## When to prefer this 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. ## Known failure modes - Invalid or unknown product_id returns empty or null data - Unsupported country code may return no results or default to US - Price history array may be empty if no historical data is available for that offer - Pagination beyond available pages returns empty offers array - Rate limiting or payment errors return 402 or 429 HTTP status codes - Truncated response schema may omit some fields for certain product types ## 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. ## Request schema (JSON Schema) ```json { "type": "object", "required": [ "product_id" ], "properties": { "page": { "type": "integer", "default": 1, "description": "The page of offers to return price history for.
